A Quick Overview of The Running Configuration

A configuration that is in the router’s memory is called a running configuration. The interface of this config can be changed by changing the setting of the router.

Network communication defines a set of protocols that allow application programs to communicate with each other regardless of the hardware or operating system on which they are running. 

The network communication system is a collection of individual telecommunications systems, transmission systems, relay stations, substations, and terminals, which can usually be connected and operated together to form an integrated whole. 

Types of Network Communication 

Network connections work differently under each command, which allows the application program to define the actions performed. Some types of network connections are: 

  • Local Area Network (LAN) 
  • Metropolitan Area Network (MAN) 
  • Wide Area Network (WAN) 
  • Wireless. 
  • Inter-Network (Internet) 

Network Configuration 

When you enter a command in global configuration mode, the command is saved in the current configuration. The running configuration is in the device’s RAM. Therefore, when the device is powered, all configured commands are lost. 

To avoid getting your command lost, you need to copy the current configuration to the starting configuration. The startup configuration is stored in the device’s non-volatile memory. This means that all configuration changes are retained in the event of a device power failure. 

How to Open Startup Configuration? 

The startup-config command is stored in the device’s non-volatile memory. That is, all configuration changes are retained in the event of a device failure. To copy the current configuration to the startup configuration, you need to enter the command copy running-configuration or startup-configuration. 

A persistent copy of the Cisco router configuration file is called the startup-config file. The startup-config file is kept in NVRAM, and the contents of the startup-config file are kept after a reboot. 

What Does Startup Configuration Do? 

The startup configuration file is stored in NVRAM and contains the commands needed to initially configure the router. It also creates an execution configuration file that is stored in RAM. 

Some of the main purposes of startup config command are: 

  • to provide the basic function of the hardware of a device. 
  • to initiate the commands that are used to configure a router on startup. 
  • to contain the config commands that the router IOS is currently using. 
  • to provide a limited backup version of the IOS, in case the router cannot load all the features. 

Overview of Running Configuration 

Configuration changes made in global configuration mode only to affect the current configuration of the router. Rebooting the router will reset the settings to their previous settings. This is because the router pulls the configuration from NVRAM at boot time. This configuration is called startup-config. If you want your configuration changes to be permanent, you need to save them to NVRAM. 

The current configuration is volatile information. All changes to the switch are displayed in the current configuration. The Cisco switch stores this configuration file in memory instead of NVRAM. So, when the light goes out, it goes out too. Use the show running-config command to display the running configuration. 

How to Configure Router and Switch

Making changes to the settings of your router could be an overwhelming task. However, as many IT experts know that default settings don’t always represent the most secure even if adhering to the default settings requires no effort or effort. The default settings are generally unsafe and aren’t the most effective option to support networking connectivity. Similar to all devices and software, there are always hidden capabilities waiting to be made use of by an aspiring IT expert. Making adjustments to your IT infrastructure settings is essential to optimize and secure your network, no matter if it’s the corporate or small business setting.

In reality you don’t need to be an expert or tech-savvy to get the most benefit from the router settings options that are available to you. With the right information at hand, you can adjust the settings of your router to meet the specific needs of your company.

In this article I’ve provided a list of guidelines to help you discover how to configure the routers or switches you have. I’ve also emphasized the basic configurations for those who are just beginning to tweak the hardware of your network. If you’re planning to further expand this knowledge I recommend investing in a tool such as SolarWinds (r) Network Configuration Manager as an automated program goes to a great extent in optimizing and managing changes to network configurations and configurations particularly for larger networks.

The benefits of a Router and Switch Configuration

One of the major benefits of switching and router configuration is that you can enhance security in many ways. The first thing that you could do is alter the password for your router from default to something more secure and distinctive. This stops hackers from gaining access to the router’s settings. By using the router, hackers might be able to disable the wireless security of your network, which could allow them to gain access to sensitive or private company data without even.

Changing the service set Identifier (SSID) or called the network name, is another alternative. The change in your SSID helps identify your network faster. Additionally, certain routers use a default SSID to indicate the type of router utilized, making it easier for hackers to penetrate your network. Although it’s only a minor change changing your default SSID is still at the top of your list of things to do.

You can also set router settings to conceal the IP address of your local network. You can alter your IP address through tweaking your settings. The primary reason to do this is to ensure your privacy on the internet, which makes it difficult to have your activities traced back to your identity. This is a further useful security feature, but not always a top priority in business.

You can also configure settings to allow multi-SSID as well as guest Wi-Fi. The majority of modern wireless routers are capable of broadcasting multiple access points simultaneously. A single access point may be used by well-known and reliable devices, and a different access point is available to accommodate guests. One of the main benefits of this is that you do not need to share your primary Wi-Fi password with anyone else or guests, which reduces the chance of over-use or overloading. You can also set the settings of your router to display who is connected. This is useful since the possibility of someone stealing your bandwidth could result in fluctuating or low internet speeds.

The router’s programming lets you switch Wi-Fi channels and bands which can enhance the Wi-Fi speed and coverage significantly. Most wireless routers will select the right channel automatically for you when you first install them. The selection doesn’t match your specific wireless network and often leads to delays or interference.

Certain routers allow you to create “parental control” or restrict employees from accessing certain kinds of sites. If you’re managing an at-home, personal network, the setting up of parental controls will protect your children from online dangers, preventing them from being exposed to inappropriate or adult content. For corporate networks, it is possible to block specific types of websites, such as video streaming or online shopping websites–to boost productivity of employees. In any case the controls fall into two categories which are Monitoring and Filtering. Filtering lets you decide which users have access to access and monitor lets you see which websites users are able to access.

Furthermore, a lot of people are unaware that you can turn on remote management through your configurations of the router (if your router supports this feature) which allows you to control your router from any location, through your phone or other device. Remote management is disabled by default.

With these advantages in mind, I’ll describe how to adjust router settings to maximize the options that are available. Before I get started I’ll briefly define the concept of a switch and the reason you might be thinking about switching configuration.
