Configuring the Interfaces
The following sections describe how to configure interfaces and also provide examples of configuring the router interfaces:
Configuring the Interfaces: Example
The following example shows the interface gigabitEthernet command being used to add the interface and set the IP address. 0/0/0 is the slot/subslot/port. The ports are numbered 0 to 3.
Router# show running-config interface gigabitEthernet 0/0/0
Building configuration...
Current configuration : 71 bytes
!
interface gigabitEthernet0/0/0
no ip address
negotiation auto
end
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# interface gigabitEthernet 0/0/0Viewing a List of All Interfaces: Example
In this example, show interfaces summary command is used to display all the interfaces:
Router# show interfaces summary
*: interface is up
IHQ: pkts in input hold queue IQD: pkts dropped from input queue
OHQ: pkts in output hold queue OQD: pkts dropped from output queue
RXBS: rx rate (bits/sec) RXPS: rx rate (pkts/sec)
TXBS: tx rate (bits/sec) TXPS: tx rate (pkts/sec)
TRTL: throttle count

Viewing Information About an Interface: Example
The following example shows how to display a brief summary of an interface's IP information and status, including the virtual interface bundle information, by using the show ip interface brief command:
Router# show ip interface brief
