Configuring Cisco Router Interfaces Posted: 15 Jul 2010 11:14 AM PDT One of the main elements to configure on a Cisco router is its interfaces. The router is usually equipped with Ethernet interfaces (for LAN connectivity) or Serial/ATM/T1/E1 interfaces for WAN connectivity. Below you will find three typical router interface configuration scenarios to get an idea about this important setup. Configuring Ethernet or Fast Ethernet Interfaces Router> enable Router # config terminal ! enter the interface configuration submode Router(config) # interface fastethernet 0/0 ! IP configured on the interface Router(config-if) # ip address 10.1.10.1 255.255.255.0 !bring the interface up Router (config-if) # no shutdown Router (config-if) # description lan (assign a name to the interface) Router (config-if) # exit Router (config) # * Note that the interface naming can be different. Examples are FastEthernet, Ethernet, GigabitEthernet etc. Also, the interface numbering varies from router to router, such as 0, 1, 0/0 0/1, etc. Configuring DTE Serial Interfaces Note that DTE serial interfaces receive clock from the Serial WAN modem. Router> enable Router# config terminal ! enter the interface configuration submode Router (config) # interface serial 0/0 Router (config-if) # ip address 172.16.1.1 255.255.255.252 Router (config-if) # no shutdown Router (config-if) # description WAN Network (assign a name to the interface) Router (config-if) # exit Router (config) # * Note that the interface numbering can be 0, 1, 0/0 0/1, etc. This varies by router. Configuring DCE Serial Interfaces Note that DCE serial interfaces provide clock to the connected device on the interface. Router> enable Router# config terminal Router(config) # interface serial 0 / 1 Router(config-if) # ip address 10.1.1.1 255.255.255.0 !configure the clock rate that will be provided by the router Router(config-if) # clock rate 128000 Router(config-if) # no shutdown Router(config-if) # description WAN Network (assign a name to the interface) Router(config-if) # exit Router(config) # * Note that the interface number can be 0, 1, 0/0 0/1, etc. This varies by router model.
