1. On the Cisco 2901 router, the numbering format for configuring an asynchronous interface is 0/slot/port. To configure the line associated with an
asynchronous interface, simply use the interface number to specify the asynchronous line. For example, line 0/1/0 specifies the line associated with
interface serial 0/1/0 on a WIC-2A/S in slot 1. Similarly, line 0/2/1 specifies the line associated with interface async 0/2/1 on a WIC-2AM in slot 2.
2. MGF = multi-gigabit fabric
3. Applies only to Cisco 2951, Cisco 3925, and Cisco 3925E routers.
4. Applies only to Cisco 3945 and Cisco 3945E routers.
5. Applies only to Cisco 2951, Cisco 3925, and Cisco 3925E routers.
6. Applies only to Cisco 3945 and Cisco 3945E routers.
7. Applies only to Cisco 2951, Cisco 3925, and Cisco 3925E routers.
8. Applies only to Cisco 3945 and Cisco 3945E routers.

Command Purpose
Step 1
interface gigabitethernet slot/port
Example:
Router(config)# interface gigabitethernet 0/1
Router(config-if)#
Enters the configuration mode for a Gigabit
Ethernet interface on the router.
Step 2
ip address ip-address mask
Example:
Router(config-if)# ip address 192.168.12.2
255.255.255.0
Router(config-if)#
Sets the IP address and subnet mask for the
specified GE interface.
