Cisco Cisco IOS Software Release 12.0(19)S

The 

 provides a variety of 

examples for defining SONET channels on the line cards.

After the SONET or SDH channels have been defined, you must activate the channels using the 
configuration command microcode reload slot. This command is also used to activate the channels after 
a change has been made to the channelization configuration. 

This command reloads the line card in the specified slot. Traffic is disrupted on all interfaces for that 
slot. 

To modify the existing channels on a line card controller, complete the following steps:

In channelized ISE line cards configured for APS, the channelizations for the working and protect 
ports must be identical. If the channel configuration is changed for a working port, those same 
changes must be made to the protection port (and vice versa). If the channelization configurations on 
the working and protect ports are different when a protection switch occurs, the traffic carried by any 
mis-matched interface will be lost. 

Router# configure terminal

Enters configuration mode, if necessary.

Router(config)# microcode reload slot

Activate the interfaces on each port for the line 
card in the specified slot. After entering the 
command, wait for the microcode reload to 
complete.

slot is the physical location of the ISE line card.

Router(config)# show controller provision slot

Displays the active interfaces for the line card in 
that slot. Use this command to verify that the 
defined interfaces are activated.

Router(config)# end

Exits configuration mode.
