Cisco Cisco IOS Software Release 12.0(19)S

Channelized line cards allow each physical port to be configured into “channels”. This feature allows 
multiple connections to be configured over a single physical port. Each of these channelized interfaces 
utilizes a portion of the port’s available bandwidth. The entire bandwidth of a port can also be configured 
as a single channel, if required.

To configure the channels on an ISE channelized line card, the controller for each card is first configured 
to define framing type (SONET or SDH) and related parameters. When this is done, the controller is 
enabled and the system clock for that card is configured.

After the line card controller is configured, the individual channel interfaces are defined. Finally, those 
interfaces are configured for encapsulation and other parameters. 

For information on the configuration and use of Bit Error Rate Testing (BERT), refer to the 
appropriate hardware installation publications as specified in

This section contains instructions to configure the attributes that apply to all traffic on the controller 
(physical port). 

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

This section describes the commands used to select a controller and modify the parameters. This section 
also includes the default settings of each command. Each task in the list is identified as either required 
or optional.
