How do you set the IP address for the ethernet port of a router?

Following are the steps needed for setting the port address for the ethernet port of a router.

• First go into global configuration mode
  
  # conf t
  (config)#


• Now go into interface configuration mode for the port whose address you want to set as follows ...
  
  (config)# interface ethernet 0
  (config-if)#


• Here give the command to allocate an address 192.168.0.1 and a subnet mask 255.255.255.0 as follows ...
  
  (config-if)# ip address 192.168.0.1 255.255.255.0
  (config-if)#no shutdown
  (config-if)#^Z

Now if you give the command show running-config from the previledged mode, you can see that the ethernet 0 interface has been allocated the said ip address. And the no shutdown command says that the ethernet 0 interface has to be turned up.
