Slot and Subslot Configuration

This chapter contains the following sections:

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 0/0/0

Viewing 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
