Cisco Cisco IOS Software Release 12.0(19)S

After the channels have been defined as outlined in 

, the 

parameters for the individual interfaces (channels) can be set. Each channelized interface operates as a 
separate connection, and can be configured as outlined in this section.

By default, all interfaces are disabled. To enable an interface, you must first choose the interface, and 
then issue the no shutdown command. When an interface on the line card is enabled with no additional 
configuration, the default interface configuration parameters are used. 

This section describes the commands used to select an interface and modify the parameters. This section 
also includes the default settings of each command. 

 

Enter one of the following commands to select the appropriate interface. After the interface is selected, 
continue to the appropriate interface configuration section.
