ICTNWK612 - Plan and Manage Troubleshooting Advanced Integrated Systems

Plan to monitor and manage the IP network to optimise its performance and reliability 

Purpose: Monitoring a network serves many purposes, the most important of which are to offer insurance and to investigate the presentation of the computer and networking system in order to determine whether or not something is wrong or not if anything needs to be traded. In addition, do improvement testing for each and all users or clients who would want an easily accessible component of the system's assets.

Time Frame: It is suggested that this plan of action be carried out over the course of a period of three months in order to construct a research-based institution of learning, put the concepts into action, create a training, and compile a risk analysis.

Person responsible: These implementations are the responsibility of a large number of individuals. Between the three of them, we may refer to them as the talent acquisition and retention team, the team that assists with information technology, and the finance team.

Supervised by: The owner of the company as well as the engineers working for it are the ones in charge of providing oversight.

Parameters: It is advised that the firm that is being studied should begin using new kinds of gadgets as part of their operations. This organisation is connected with details on the structure, the difficulty of adhering to it, the obligations, and the positions that are assigned. The provision of customers, non-open support, and collaborators with reliable access to newly released items is the major goal of arrangement plans, and this target applies regardless of the physical location of the business in question. It might refer to a single site or a number of different places.

Identify the critical devices on your network

Routers, firewalls, switches, web servers, file servers, load balancers, intrusion detection systems, domain name systems servers, and storage area networks are examples of essential equipment. Because the majority or perhaps the whole of organisational and customer traffic is required to flow via critical equipment, these devices provide excellent targets for malevolent cyber actors.

Identify Network Data Sources

A source of data is the site where the data that is now being utilised originated from in the first place. In the most basic sense, a data source may take the form of a repository, a flat file, continuous observations from physical devices, data scraped from the web, or any one of the many static as well as streaming data services that can be found all over the internet.

The key data sources for network monitoring are:

o Flow Data: The movement of data from one system element to the next illustrates the flow of information (and other times, physical objects) across the system. The arrow may be seen as a representation of the flow. A name need to be given to the flow, and that name ought to explain what kind of information (or what kind of material) is being transported.

o Packet Data: A unit of data that is combined into a single container and sent over a specified network route is referred to as a data packet. In addition to being used by Internet Protocol (IP) communications for data that travels through the World Wide Web, data packets are also utilised by other types of networks.

o Wifi Data: One can do essentially the same thing with a data plan that one do with a Wi-Fi network, which is access the Internet wirelessly. Users may have the best of both worlds with a data-enabled smartphone, depending on how often users use the Internet and where users do it: quick and safe access to data users need when users are really on the go, as well as some leeway in terms of your total data use.

Apply the Right Network Traffic Monitoring Tool

o NetFlow Analyser: The monitoring, troubleshooting, in-depth examination, analysis, and composition of traffic flow data are all tasks that may be accomplished with the use of a tool called a NetFlow analyzer. Analyzing NetFlow not only makes capacity planning more accurate but also ensures that assets are used in the most effective manner possible in order to support corporate objectives.

o Packet Analyser: A piece of hardware or piece of software that is used to monitor the traffic on a network is called a packet sniffer. This tool is also known as both a packet analyzer, protocol analyzer, and network analyzer. Sniffers perform their function by inspecting the streams of packets of data that move between the computers that are connected to a network and between networked machines and the Internet as a whole.

o Network Monitoring Reports: The tracking system reports provide information that is essential to track patterns in resource use and to plan improvements; in addition, reports and logs offer the option to trace outcomes above certain time period.

Monitoring Traffic from Specific Network Manufacture

It should come as no surprise that monitoring traffic on the network in large, enterprise-level businesses is very unique than routing traffic in a headquarters. But even while this is true, it is still worth noting. The vast majority of large companies are active in a variety of industries, some of which include AWS, and Azure. Filtering network traffic becomes an increasingly difficult task as the network environments of big enterprises continue to expand. It is essential to have a solid understanding of how to manage network traffic if you want to make sure that your network is operating at its full potential.

Optimise Network Traffic

o Overall Network Performance Optimisation: The technology, techniques, and tactics that allow the maintenance, enhancement, and improvement of efficiency throughout all network domains are together referred to as "network optimization." These devices are used to monitor, regulate, and enhance key metrics in order to aid in providing users of the network with the highest possible quality of service.

o Optimisation Using Forensic Analysis: The following are examples of traditional approaches used in forensic analysis: cryptanalysis, reverse engineering, steganography, cryptology, and forensic engineering.

o Optimisation of Voice, Video and Unified Communications: It is a common idea that the only necessary components of a UC solution are "presence," "user interface," and "integration with voice capabilities." However, the other components give a solution that is more fully featured.

o Optimisation to Quality of Service Levels: Impose stringent restrictions, and bring into play a variety of circumstances that have the potential to affect the network's quality of service. As a result of elements such as instability, throughput, and packet loss, it is simple for the quality of service to be negatively impacted by the delaying or losing of packets.

Plan to isolate the network segments for troubleshooting 

Purpose: Network segmentation is the notion of having taken ones network as well as splitting it into processing facilities that are named VLANs (virtual network networks). These VLANs separate resources in the network as according one‘s department in an organization either according to another conceptual framework that you define to differentiate lower levels of security from greater, more restricted levels. Network segmentation is also commonly known as network isolation. Because of the growing number of companies that need to be PCI compliant, a growing percentage of enterprises are being obliged to plan, build, and implement a network that is segregated. Despite the wealth of information that is now accessible on the topic, there are still a great number of businesses who are unable to launch.

Time frame: It is advised that these projects be implemented after a period of three months to allow for development.

Parameters: The very first thing that Have you settled on the deployment of a new network, or do you want to reorganise a flat network that is already in place? When you are reorganising an existing network, it is important to keep in mind that the scale of the network itself will have a significant influence on the duration of the project.

Use the principles of least privilege and need‐to‐know

It is recommended that you address this issue by using a clearly outlined project timeframe in conjunction with a work breakdown structure (WBS). I'm not proposing that you should immediately include the Program Management Office of your company, but you certainly might (PMO). My suggestion is to use either a cloud-based project management solution that is free with optional paid upgrades or free project management Excel templates that can be downloaded from a variety of websites that focus on project management. In light of the fact that other stakeholders will be involved in this project, I propose that we use a project management system that is hosted in the cloud. This will ensure that all participants in the project have access to the project schedule as well as the tasks that have been assigned to them.

Separate Hosts and Network

A computer or other device that allows other devices to connect to it in order to have access to its resources (files) or services (web site/email/database/etc.) is referred to as a host. A collection of computers, cables, routers, switches, and other devices that are linked to one another in order to get access to and share resources is known as a network. Advantages of Being Able to Segment Your Network Performance Enhancement: Since there are fewer sites in each subnet, the amount of local traffic is reduced. Isolating broadcast traffic is possible using a local subnet. Enhanced Containment - If there is a breach in the network, the effects of the breach are confined to the local subnet.

Zooming in the Authorisation Process

OAuth integrated with Zoom. Users are authenticated and granted permission to make requests through OAuth 2.0 while using the Zoom API. You will need to build an OAuth app on the Marketplace in order to configure your app's access credentials and request scopes. Your application's server is the only place from which calls may be made to Zoom's OAuth and API endpoints.

Network Traffic Whitelisting

Commercial whitelists are a method via which an Internet service provider (ISP) would, in exchange for a pre-paid fee, either an annual or a per-message cost, let a third party to circumvent the ISP's spam filters when that third party sends email messages to the ISP's customers.

Infrastructure Testing In Cloud

Testing the infrastructure in the cloud helps to guarantee that the programme will be installed without any errors in the production environment. It is helpful to have an understanding of the application's performance, scalability, and stability. It assists in making use of the resources that may be discovered in the cloud, including any hardware, software, and infrastructure.

Network-level Testing

In its most basic form, penetration testing is a simulation of the procedure that a hacker would follow in order to start an assault on a company website, a business network, or any of the connected devices or apps on the network. The simulation's goal is to detect vulnerabilities in the system before malicious actors may find them and use them to their advantage.

Installation/Uninstallation/Deployment

Before you may deploy an application using the Uninstall action, you must first remove any previous application deployments, simulated application deployments, or task sequence deployments that contain this application. In such case, Configuration Manager may perform a fresh installation of the programme.

Test Environment Infrastructure

Testing the infrastructure in the cloud helps to guarantee that the programme will be installed without any errors in the production environment. It is helpful to have an understanding of the application's performance, scalability, and stability. It assists in making use of the resources that may be found in the cloud, which may include any hardware, software, or infrastructure.

TDD Approach

Test-driven development, or TDD for short, is a method in software development that places an emphasis on the creation of unit test cases prior to the development of the real code. In simpler terms: Programming, the development of unit testing, and refactoring are all elements that are brought together in this iterative methodology.

Network testing tools 

OpManager is a centralised location for all aspects of network testing. ManageEngine OpManager is an easy-to-use and comprehensive network testing tool that can be used to any and all networks. OpManager offers a wide variety of tools for testing networks, each of which delivers findings in real time that are accurate and up to date. Additionally, it automates network testing, which reduces the amount of resources used while simultaneously saving valuable time. The following are some of the reasons why a tool for testing networks is necessary: The most important purpose of a network is to facilitate the efficient flow of resources. It is essential to do regular network testing using technologies that have a solid reputation in order to: Recognize the current state of the network. Verify that the alterations made to the configuration are working properly.

Locate dangers on the network that have the potential to cause severe damage. Provide an outstanding experience for the final user. Administrators of information technology face a wide array of challenges. Even in a setting with few interconnected devices, running network tests is a challenging task for a network administrator due to the substantial amount of resources and human labour that are required. It takes a significant amount of time and effort to conduct a network test when many testing tools for networking are used since each tool has to be started and terminated in turn. A certain degree of administration is necessary for the network testing tools, which includes the allocation of storage space, the clearing of cache, the beginning and ending of essential services, and the upkeep of open ports. Keeping track of a few different tools at once may quickly become a burdensome task in and of itself.

Network monitoring tools 

Open-source monitoring solutions can need a significant effort and resource investment on the user's part. The intervention of the community support or an in-house IT team may be required to restore previously unavailable capabilities. The second thing to keep in mind is security, which is something that may become an issue depending on the product that you use and the security regulations that are in place at your firm. In addition, it's possible that you won't be able to acquire speedy custom solutions unless you construct them and manage them yourself, which would take time If this sounds like something you would be interested in, continue reading. ipMonitor is an easy-to-use, lightweight, and speedy solution that offers scalable network monitoring for your whole network.

ipMonitor will even provide recommendations for what aspects of each of your applications and devices you need to be keeping an eye on even before you install it. One of the reasons someone would decide to use a free network monitoring service rather than a paid one is to prevent the feeling of being overwhelmed by a premium solution. In point of fact, paid network monitoring solutions often have a far more intuitive interface than their respective free counterparts. This is particularly true when using ipMonitor, due to its user-friendly interface, which allows you to quickly notice present problems (and even prospective difficulties), enabling you to repair them before they wreak havoc on the performance of your network. The powerful and fully customizable alerting mechanism provided by ipMonitor helps to ensure that you will never miss anything important. Because it includes more than a dozen distinct notification types, ipMonitor gives you the ability to ensure that the appropriate members of your team are alerted as soon as the tool identifies a potential problem. ipMonitor also gives you the ability to customise the notifications that are sent out.

Software application to suit the network troubleshooting and monitoring sequence 

WhatsUp Gold is a powerful and user-friendly software solution for monitoring the totality of systems, including applications, networks, and other software. It gives you the ability to detect problems before they have a chance to affect the user experience. In addition to this, you may get an accurate representation of the performance of your IT infrastructure. WhatsUp Gold is equipped with a one-of-a-kind interactive map that makes it simple for users to investigate the performance of their whole network, infrastructure, and virtual environment. It provides information on the connection of network devices as well as a dynamic reaction to contacts, so guaranteeing that the response time is kept to a minimum. The snapshot of the physical, virtual, and wireless networks may be obtained via the use of the interactive maps by filtering the data in a dynamic manner. You have the option to zoom out to receive a more comprehensive view of the topic at hand or to zoom in to get a more detailed examination of certain websites or devices. The environment may be represented on a map in a variety of ways, including geographically (on a map or a building map), technically (by connection, application, or commerce), or in any other way that the designer chooses.

The surveillance setup process is significantly sped up as a result of the tool's smart discovery method, which starts with the tool's usage and begins with finding all of the devices that are connected to your network and automatically assigning them either standard or bespoke device roles. The active and passive monitors for SNMP traps, Syslog, and Windows event logs are all included in the WhatsUp Gold package. Utilization of the central processing unit (CPU), hard drive, memory, and network resources are measured by performance monitors using SNMP, SSH, or WMI. It is possible to obtain early alerts from WhatsUp Gold when clients are experiencing sluggish response times. This enables you to solve problems before customers experience total outage. These alerts might be sent to you by e-mail, text message, or via your computer browser. In addition to this, it is equipped with a network traffic analysis module that is able to collect information about bandwidth use as well as network traffic from any device on the network that supports flow. An action policy is one of the most powerful features of performance management. When it detects a state change, such as when a router fails, it immediately creates a log entry or launches an intervention script to reboot the system some many minutes later, decided to follow by an email message. This is one of the most powerful features of performance management.

Manage strategies for network monitoring structure

Understand of what devices make up your network

The term "enabling communication" refers to anything that makes it easier to move data from its point of origin to its final destination. This might be anything as simple as a network switch transferring frames between two devices on a local area network (LAN). Limiting one's ability to communicate is obstructing their ability to do so. Both a rule on a firewall that stops traffic from accessing TCP port 23 and a virtual local area network (VLAN) that divides broadcast domains are examples of this kind of separation. It should be brought to your attention that nowhere in our explanation of network devices do we use the word "hardware." This is due to the fact that a significant portion of the network's services and equipment are either virtualized or are software-based. You could, for instance, develop a virtual appliance that combines the capabilities of a router, network switch, and firewall.

Configuration & change management

Make sure the right person is alerted to problems

Monitor all your layers

In order to keep these kinds of performance-related financial losses under control, measurements are necessary. The primary goal of this process is to observe the activity and reactions of materials in various architecture and design levels of implementations in order to avoid efficiency damages suffered by trying to control things that we cannot measure or even accomplish with an assertive action plan. In order to do so, the process's main aim is to monitor the behaviour and public reaction of components in different architectural levels of implementations.

Prepare for future network expansion

Virtualization of network functions and software-defined collaboration will play increasingly important roles in the future of networking. These technologies will transform functions that were previously performed by specialised hardware or locally hosted virtualization software into software that is hosted in the cloud and executed remotely.

Ping

Ping is a network service that relates to the signal that is sent out over the networks to that other system, which then sends its own feedback signal. Ping is used to determine whether or not the other computer is online. This message, which is recorded in milliseconds (ms), will determine how long it takes for a piece of data to go from your computer to a server on the network and back again. Milliseconds are the unit of measurement for this signal.

Monitor strategies for network monitoring structure 

Simple Network Management Protocol (SNMP

When an SNMP manager queries the agent, the agent locates and transmits this information to SNMP management systems. SNMP manager—(alternatively called SNMP server) This component acts as a centralized management station for an SNMP management application running on a variety of different operating systems.

Syslog

Messages may be sent from connected devices to a logging server, which is commonly referred to as a syslog server, using a method called the syslog protocol. This method has been in use for many years. The syslog protocol has been around for a long time and is quite popular; as a result, it is supported by the majority of the main operating platforms, notably macOS, Linux, and Unix.

Leveraging the Power of Scripts

Code level monitoring is something that has to be done in order to figure out why some procedures are slow or throw difficulties, as well as what kinds of errors are there in the programme. Agents are installed on application servers in order to achieve this goal. These agents collect data on the response time as well as any problems that are linked with operations performed on the server. When an application server begins to run more slowly than usual, the developer is tasked with determining whether or not the sluggishness is the result of a fault with the program's source code. Generally speaking, the creation of a process profile offers application owners and developers the ability to go deeper into the code and get a method-level analysis of the length of the process. It is feasible to pinpoint the precise position of the line of code, database query, or call to a third party that was responsible for the lengthy execution time of a user process when the process takes a long time to finish.

Routine internetwork operating system (IOS) device maintenance plan to include monitoring of routing protocols and router configurations 

Purpose: The starting procedure of the router is the source of a collection of difficulties that occur less often but pose a greater threat. In the absence of a properly functional router, the device is practically pointless. It is essential for administrators to have a solid understanding of the actions they might take in the event that their router does not start up properly. Because of reason, it is quite important that you realise this for the examination. A configuration register is a 16-bit register that is present in Cisco devices. This register is used to govern the behaviour of routers.

The baud rate and broadcast addresses of the terminal may both be modified using this option. Nevertheless, the thing that has us the most concerned is the possibility that changing the configuration setting would have an effect on how the router starts up. When it comes to fixing difficulties that are associated with booting, this might be a very helpful tool. The first thing you'll want to do is figure out how to enter the read-only memory (ROM) Monitor mode on the router. This will allow you to make direct changes to the router's files and configuration settings without having to restart the device entirely. To enter ROM Monitor mode on your router, you need to either change the settings to 2100 or press the Ctrl-Break key simultaneously when the router boots up.

Time Frame: Over the course of the course of three months

Person responsible: Information technology systems manager

Procedure

Obtain IOS Updates:

If you are really operating in ROM Monitor mode, the IOS prompt on your current router will read rommon 1>, but the IOS prompt on older routers would just read >. After entering the ROM Monitor mode, you will be able to begin making changes to the router's configuration files and other files. The architecture of routers is built such that they are capable of performing two primary purposes: processing routable protocols and using routing protocols to identify the optimum path. Routers are equipped to execute these duties. A router may be broken down into the following four parts: Ports for input. The input port is responsible for a few different functions. Alternating between fabrics The routing device's input ports and output ports are linked together via the switching fabric. Output ports. This consists of things like the sizes of routing tables, convergence times, and failure detection... In this piece, we're going to take a look at some fundamentals that might help enhance routing. In this discussion, rather than concentrating on particular routing protocols, we will take a more generic approach.

o Run-from-Flash Routers

Find the button on the back of the router labelled "Reset" and make sure it is plugged in before you attempt to use it. To press and keep the button down for the whole 15 seconds, you need need a pin or a pencil. When you have successfully reset the router, you will see that the lights on the back of the device flash simultaneously. This is how you will know that the router has been reset.

o Run-from-RAM Routers

On a router, the random access memory (RAM) is utilised to store the running Cisco IOS Operating System as well as IOS system tables and buffers. Additionally, RAM is utilised to store routing tables, maintain ARP cache, and perform packet buffering (shared RAM). While the router is switched on, the router file name may use the memory provided by the RAM as a temporary storage location.

o Use the Flash Load Helper

Out of all the many kinds of memory that Cisco offers, flash memory has the most applications. The most important function of flash memory is to serve as a repository for bootable IOS images, which the computer system may then define and utilise to boot up. The whole Operating System Image is stored on the memory's flash drive (IOS, Internetwork Operating System). This enables you to update the operating system (OS) without having to remove any chips. The contents in flash memory are preserved even if the router is turned off and restarted.

Upgrade Run-from-RAM IOS Images

The average size of an iOS update is between 1.5 and 2 gigabytes (GB). However, in order to download and install the update, you will want a space that is twice as large. If you want to err on the side of caution, you should have around 4 gigabytes of free space on your device before attempting to install a new version of iOS. Go to Settings > General > iPhone Storage in order to see how much free space is currently available on your iPhone.

Isolate suboptimal internetwork operation

Data Link Layer addresses:

After the packet is broken up into frames at the network layer, it is given to the data link layer to process. The MAC addresses of the source and the destination are included in the header for this layer. It is the responsibility of the data link layer to first transform the data into binary digits such as 1 and 0, and then to get those digits ready for the physical layer. There are three different kinds of addresses that are defined by several link-layer protocols: unicast, multicast, and broadcast. Unicast addresses are those that are specific to a single host or interface on a router. One-to-one communication is what's meant by the term "unicasting." A frame that has a unicast address destination is only going to be sent to one of the entities that are part of the connection. In order to ensure that the data is reliably sent, the data link layer is responsible for creating data packets out of the data bits and "frames." This layer is responsible for adding information to the data stream that may identify and correct transmission issues, as well as adding the source and destination addresses.

MAC Addresses:

A media access control address, often known as a MAC address, is a one-of-a-kind identification that is given to a network interface controller (NIC) in order for it to be used as a network address in communications that take place inside a network segment. This use is typical in the vast majority of networking technologies based on IEEE 802, such as Ethernet, Wi-Fi, and Bluetooth. A media access control address, often known as a MAC address, is a unique identifier that is given to network interface devices (NICs). A physical address or a hardware address is another name for it. It is used for networking communication systems inside a network segment in addition to serving the purpose of identifying the hardware manufacturer.

Network-Layer Addresses:

Logical addresses are converted into their corresponding MAC addresses via the Network layer protocol. For instance, in a standard Internet Protocol (IP) address like 192.168.1.102, the network is 192.168.1, as well as the machine address, which is referred to as a host address in IP, is 102. In a manner analogous, IPX addresses are made up of two components: the network address and the node address.

Following IOS troubleshooting tools and techniques

· Use Router Diagnostic Commands

A reboot of the operating system may be triggered by entering the config mode and using the reboot command. This action is the same as issuing the shutdown -r command from inside a shell prompt.

· Using show Commands

Show-Command is a very helpful tool for both teaching and learning. ShowCommand is compatible with every command type, including cmdlets, functions, workflows, and CIM commands, among others. The Show-Command command, when used without any arguments, brings up a command window that shows all of the accessible commands for all of the installed modules.

· Using debug Commands

In software development, the debugging process begins when a developer locates a code error in a computer program and is able to reproduce it. ... For example, an engineer might run a JTAG connection test to debug connections on an integrated circuit.

· Using the ping Commands

Launch an interactive command prompt. After selecting the Start Menu, put "cmd" into the search field and then hit the Enter key on your keyboard. In the box that says "Command Prompt," write "ping," followed by the destination, which may be an IP Address or a Domain Name, and then hit the Enter key. The results of the ping will start to be printed into the Command Prompt after the command is executed.

· Using Cisco Network Management Tools

How exactly do the systems that monitor networks function? They often do this by sending a signal known as a ping to different system ports, which allows them to verify the activity and health of internal systems over the network.... In general, the majority of services that monitor networks do tests on the server ranging from once every hour to once every minute.

Monitor security issues related to IOS services for mission critical applications 

TDRs and OTDRs

Time domain reflectometers are at the pinnacle of the spectrum of cable-testing equipment (TDRs). An optical time domain irradiates is used in the process of measuring fiber-optic transmission (OTDR). OTDRs have the ability to correctly determine the distance of the fibre, find cable breakage, measure the attenuation of the fibre, and quantify the losses that occur at splices or connectors.

Breakout Boxes, Fox Boxes, and BERTs/BLERTs

The digital signals that are present at PCs, scanners, telephones, the multichannel service unit/digital support information (CSU/DSU), and other input / output devices may be measured with the use of testing instruments such as breakout boxes, fox boxes, and tad over the top error rate testers (BERTs/BLERTs).

Network Monitors

The usage of a system that continuously monitors a computer network for components that are running slowly or malfunctioning and that warns the network administrator (by email, SMS, or other alarms) in the event of outages or other types of difficulties is what is meant by the term "network monitoring." Network administration includes activities like monitoring the network.

Network Analysers

An instrument known as a network analyzer is one that can measure various network properties in relation to electrical networks. Network analyzer are often used in the process of characterising two-port networks, such as amplification and filters; nonetheless, these devices are versatile enough to be utilised on networks including any number of ports.

Plan the testing sequences and scenarios of network infrastructure

Purpose: Legacy IPv4 applications need to be able to continue interacting with more modern IPv6-enabled applications even when the transition from IPv4 to IPv6 is being phased in gradually. At first, businesses provide dual-stack host and router systems to their customers. A protocol stack known as a dual-stack is one that is compatible with both IPv4 and IPv6. IPv4 applications will continue to run in a dual-stack environment, which will always have at least one IPv6 interface. These applications do not need any changes or porting work to be done. IPv6 programmes that are being executed in an environment that supports both IPv4 and IPv6 may utilise both protocols at the same time.

Applications that utilise IPv6 do so by using an IPv6 address that has been mapped to an IPv4 address. As a result of the design of IPv6, it is no longer necessary to have separate programmes for IPv4 and IPv6. For instance, it is not necessary to have an IPv4 client on a dual host in order to "talk" to a server that is running on an IPv4-only host. In addition, it is not necessary to use a separate IPv6 client in order to interact with an IPv6 server. All that is necessary is for them to transfer their IPv4 client application over to the new IPv6 application programming interface. Only IPv4–enabled servers are compatible with the client's communication capabilities. Moreover, the client may communicate with IPv6 servers which were either or dual IPv6–only. These servers may be IPv6–only.

Legacy IPv4 applications need to be able to continue interacting with more modern IPv6-enabled applications even when the transition from IPv4 to IPv6 is being phased in gradually. At first, businesses provide dual-stack host and router systems to their customers. A protocol stack known as a dual-stack is one that is compatible with both IPv4 and IPv6. IPv4 applications will continue to run in a dual-stack environment, which will always have at least one IPv6 interface. These applications do not need any changes or porting work to be done. IPv6 programmes that are being executed in an environment that supports both IPv4 and IPv6 may utilise both protocols at the same time. Applications that utilise IPv6 do so by using an IPv6 address that has been mapped to an IPv4 address. As a result of the design of IPv6, it is no longer necessary to have separate programmes for IPv4 and IPv6.

For instance, it is not necessary to have an IPv4 client on a dual host in order to "talk" to a server that is running on an IPv4-only host. In addition, it is not necessary to use a separate IPv6 client in order to interact with an IPv6 server. All that is necessary is for them to transfer their IPv4 client application over to the new IPv6 application programming interface. Only IPv4–enabled servers are compatible with the client's communication capabilities. Additionally, the client may communicate with IPv6 servers that are either dual-host or IPv6–only. These servers may be IPv6–only. The address that the client acquires from the name server is what determines whether IPv6 or IPv4 will be used. For example, if the name server gives a server an IPv6 address, it indicates that the server is able to communicate via IPv6. The following table provides a concise summary of the interoperability that exists between IPv4 clients and servers and IPv6 servers and clients. The table operates on the assumption that the dual-stack host has both an IPv4 address and an IPv6 address in the respective name service databases.

Parameter

Description

Test period

System testing is described as testing performed on a software product that is both comprehensive and completely integrated. This testing comes under the category of black-box testing, which does not need the testing team to have prior knowledge of the internal design of the code and is carried out by the testing team. In contrast to the other test application scenarios, the system update test has its own unique characteristics. statistical comparisons should be made between ongoing test runs and those from a very long time ago.

Host

A physical device is considered to be a host if it is able to provide network access in any of the following ways: via a user interface, specialised software, a network address, a protocol stack, or in any other way. Just a few examples of these kinds of devices are computers, portable devices, thin players, and devices with several functions.

Port

When it comes to the physical components of a computer, something called a port acts as an interface between the main computer and other computers or other peripheral devices. A port is the component of a computing equipment that may be used to connect to peripherals like input and output devices. This is the most common definition of the word "port" in the world of computers.

WSDL Port

A web service is able to carry out one or more connected actions if the WSDL file containing its definition has a port type. GetQuote is an operation that serves as an example. The WSDL Editor is compatible with the following types of operational categories: Request-response. A message is taken in as an input to the operation, and another message is sent out as the final result.

OS Username and OS Password

A password and a username almost usually go hand in hand with one another. The combination of a username and a password is considered to as a login, and users are often needed to have one in order to access certain websites. For instance, in order to access personal e-mail via the website, you will be asked to provide your username as well as your password.

Confirm Password

When generating a password, many people believe it is important to add a section to validate the password.... If users enter their password incorrectly, they won't be able to use it. Users are prompted to retype their password twice while using the confirm password feature, which helps detect mistakes.

SSL

The acronym SSL refers to the Secure Sockets Layer protocol, which is a security measure that encrypts the connection that exists in between web server and a web browser. SSL certificates are required to be added to the websites of businesses and other organisations in order to protect the privacy of their customers' information and ensure the safety of online transactions.

Test loop prevention for the VLAN based solution 

Multiple switches that can communicate with one another and with the devices they are connecting are used to construct networks. On the other hand, something that is referred to as a switching loop is produced if there is an improper connection between two switches. It is essential to have an understanding of the causes and processes behind these events in order to forestall their occurrence. It is standard practise in a local area network (LAN) to link many switches for the purpose of redundancy. This results in the possibility of more than one route being between any two switches in the network. A safety feature known as redundancy assures that the network will continue to function properly even in the event that one of its links is severed.

Having linked switches does, however, provide a possible challenge in the form of a Layer 2 switching loop. When there is more than one way that can go from the source devices to the destination devices, this is known as a switching loop or bridge loop. A broadcast storm is created when switches transmit broadcast packets over each port in their configuration. This causes the switch to constantly send broadcast messages, which floods the network and creates a broadcast storm. Switching loops continue after they have begun because the broadcast packets do not have a time-to-live (TTL) value. This means that the broadcast packets will continue to be sent back and forth between the two switches indefinitely. And this brings us to the heart of the matter: as long as the loop remains intact, the accumulation of blocked traffic between switches will only increase

Test private VLANs 

Connect to your VLAN

Enter your credentials into the switch's administrative page. Proceed to the VLAN Static Routing Wizard by selecting Routing > VLAN > Routing. Enter the ID for the VLAN, the IP address for the VLAN, and the networking mask for the VLAN... Choose the ports that you would like to add to the VLAN... Click the Apply button... Click the OK button when you are presented with the window for the World IP routing mode.

Open your packet analyser program

Make use of a specialised Wireshark profile. When I first started using Wireshark and had no prior experience analysing packet captures, I felt completely confused. Obtain initial information via the use of the three-way handshake. Determine how many data packets have been misplaced. Launch the Professional Information. Turn on the Time Grap for the Round Trip.

Scan the incoming packets

There are three different kinds of scanning: Scanning open ports and services is what port scanning is all about. Scanning of a network is done in order to compile a list of IP addresses. Scanning for vulnerabilities is a technique that may detect the existence of previously identified flaws.

Test SVI 

Make sure that the VLAN this SVI represents exists in the VLAN database

You need to use the vlan database privileged EXEC command in order to access the VLAN database configuration mode. The next step is to enter the vlan command with a new VLAN ID to establish a new VLAN; alternatively, you may input an existing VLAN ID to change an existing VLAN.

Use ‘autostate’ feature to bring the SVI up

When autostate is turned off, the VLAN interface is activated regardless of whether or not the user wants it to be. The autostate feature of the configuration mode interface may be turned off using the no autostate command. The autostate command removes the line from running-config that corresponds to the no autostate directive in order to activate the autostate functionality on the configuration mode VLAN SVI.

Make sure that the SVI vlan is allowed through the trunk

To determine whether or whether the locally and peer native VLANs are compatible, you may use the show interfaces trunk command. VLAN leakage happens when the native VLAN on both ends of the connection does not match. In order to determine whether or not a trunk connection has been made between switches, you may use the display interfaces trunk command. Whenever it is practical, always setup trunk links statically.

Test switch support of advanced services 

Basic Bit Error Rate Testing (BERT)

A bit error rate tester (BERT), also referred as a "bit error ratio tester" or bit error rate proven technology (BERTs), is a piece of electrical test equipment that is used to evaluate the quality of signal transmission of individual components or the whole of an entire system.... The pattern generator sends a predetermined test pattern to the device under test (DUT) or the testing system.

RFC 2544 Testing

RFC 2544 outlines a particular battery of tests that may be carried out in order to determine how well an item is functioning. Throughput, Latency, Frame Loss Rate, and Back-to-back frames are the four tests that are defined by this set. Local Area Networks (LANs) and Wide Area Networks (WANs) are both examples of the types of networks that RFC 2544 refers to (WAN).

Multi stream Testing

A hardware-based Ethernet tester, the Multi Stream UDP/TCP Traffic Generator and Analyzer is capable of creating multi-stream Ethernet traffic of various packet length and can also analyse loopback traffic. It is able to Generate and Analyze up to 16 UDP streams of traffic of varying packet lengths at the same time.

Troubleshoot switch configuration

First Define the problem

Recently, it has come to everyone's attention that the performance of the network is not perfect or enough for the requirements. Because of the breadth of the assignment, the performance of the network must be even higher than the baseline that has been defined in order to guarantee that all workers and users have continuous access to the entire resources of the network. Assume the responsibilities of the NathanNetwork Administrator and investigate and organise the troubleshooting of the corporate network in order to guarantee the best possible performance of the network. This helps to reduce the number of assaults on the network and also increases its performance.

Gather more information

As a result, the following activities need to be carried out throughout the process of creating the method for troubleshooting: Develop a plan for the management and monitoring of the network, and put it into action. As The activity of monitoring and maintaining networks is really a far more strategic operation than its name would suggest. Not only does it need monitoring for problems around the clock, but it also requires optimising data flow and access within a context that is always changing. Complete version of the template 1. Carry out a skills audit in addition to an audit of the network devices. Your instructor or examiner will provide you with a live network as well as all of the essential testing instruments in order for you to complete the audit 

Verify ARP cache

After typing arp -a, hit the Enter key. Keep an eye on the items in the ARP cache. There need to be a separate entry for the default gateway, complete with both its Internet Protocol (IP) address and its physical Media Access Control (MAC) address. This action is finished after you have closed the command prompt.

Verify MAC address table

Establish a connection to the switch with the use of your web browser. The IP address that is used by default is 192.168.0.1. Simply pick System Manager from the drop-down box, and then choose IP Settings.

Check MAC address table on peripheral switches

Terminal into switch S2 and inspect the MAC address table both before and after executing network connectivity tests with ping. Console into switch S2 as well as view the MAC address table. Create a console connection to S2 and go into privileged EXEC mode after you're connected. After entering privileged EXEC mode, the display mac address-table command must be followed by the Enter key. S2# display the mac address table.

Fixing Native VLAN Mismatch

At least one of the two switches has to be set up such that it operates in the transparent mode. It's possible that you don't want that, but if you have no idea what this implies, then go ahead and do it: Make the necessary adjustments to the switch's VTP domain: Switch(config)# vtp domain a unique name.
