As discussed above, the configuration is very complex and for each and every interface, routing method or loopback and even login ID and password settings we need to follow a very lengthy process. 5. #3) The login command is used to verify if the password is enabled or not to login into the Router. It is very important to be able to identify quickly the various components of our configuration. This information can be extracted from the manual of the router. Explanation: A hostname can be configured with upper or lower case characters and should end with a letter or digit, not a special character. This will be very helpful, especially when you're troubleshooting things. To verify the configuration, we use the show running-config command and the output will appear similar to as shown in the below figure. Method Status Protocol, FastEthernet0/0 192.168.10.1 YES manual up up, FastEthernet0/1 10.1.5.2 YES manual up up, Interface Status Protocol Description, Fa0/0 up up ### LAN ###, Fa0/1 up up ### Internet ###, How to Set User and Password on Cisco Router, Medium-size Switched Network Construction. Running configuration files can not be deleted nor are they saved automatically. There is one privileged mode command that you will find yourself using extensively. At all times, for every line that I type into or copy into the command-line interface and hit Enter, that configuration command is going to be active and available in the running configuration. Which functionality is provided by DHCP?
Now by using the second network cable, connect the LAN port of the router to the PC’s network port. Branch#copy running-config startup-configDestination filename [startup-config]?Building configuration...[OK]Branch#, Branch#write memoryBuilding configuration...[OK]. Finally, when you shut down the interface, it will show as administratively down. #5) Now define the hostname ( router name ) and password. Explanation: The enable secret command secures access to the privileged EXEC mode of a Cisco router or switch. How to Execute command in Privileged mode ? My-Router(config-if)# ip nat outside My-Router(config-if)# exit. The below figure represents the configuration in the command line on a Gigabit Ethernet interface: Defining the loopback IP address is very crucial as it provides default routing statistics.
#2) To access the Web Interface: For accessing the router’s web interface we need to know the router’s login IP address, password, and the router’s URL.
When users access the router either remotely via telnet or via the console terminal then this kind of passwords prompts the users for authentication. It should Fail, How to Execute command in Privileged mode, use authorize— > Instructs the module to enter privileged mode on the remote device before sending any commands.authorize – yes / no – This parameter enters privileged mode on the Cisco device if authorize:yes, Your email address will not be published. The default SVI on a Cisco switch is VLAN1. To view and change the configuration of the router you have to enter into the privileged mode by entering the enablecommand. to copy an existing configuration into RAM. The first command there could mitigate the exposure caused by lack of physical security. To display entries in the ARP table, use the switch show arp command in privileged EXEC mode.

Here, please make a mark that the serial interface will not come in up state until the serial interface on Router2 is also configured and made up. routers, as well as many different protocols and features that can be used to establish a network. Please find below the generic process of installation and configuration: #1) Setting the hardware: We need a desktop PC to make a connection with the router and two network cables. We will see configuration examples for basic interface components including IP addresses and then an overview of the show commands to verify proper configuration and operations. The shut down command in interface configuration mode disables the interface, while the no version of the same command will enable the interface.
Another command that may come handy is how to break, or abort, certain things. For this reason, it is very important that changes to live production devices are always carefully planned before being implemented. The steps of configuring RIP on routers are as follows: 1) Firstly go to the configure terminal mode. #6) To find out from the remote end if the far end IP of the router, switch or any other host is reachable or not, we use “Ping” command. Here is an example of how to apply these commands: At the interface configuration mode, you can apply an IP address and subnet mask to an interface using the ip address command. Always use the ? Permalink. For this, the command is as below: RouterX (config)# router rip.
