Configuring Link Failure Reflection in Linecard-Aware Mode

The
linecard-aware-mode
option is an additional extension of the link failure reflection feature for use
in MGSCP topologies. Use this option when the subscriber-side interface and the corresponding
network-side interface of the same link are connected to the same linecard in the router.
This mode reflects a failure of one port to the other three ports of the SCE platform differently,
depending on different failure conditions, as follows:
•
One interface of the SCE8000 is down: Link failure is reflected to the all other SCE platform ports.
•
Two reciprocal ports of the SCE8000 are down simultaneously, indicating a possible problem in the
linecard of the router to which the SCE platform is connected: In this case the failure is not reflected
to any of the other interfaces. This allows the second link in the SCE platform to continue
functioning without interruption.
Use the
no
form of this command with the
linecard-aware-mode
keyword to disable the linecard aware
mode without disabling link failure reflection itself.
How to Enable Linecard-Aware Mode

From the SCE(config if)# prompt, type

How to Disable Linecard-Aware Mode
Step 1

and press
Enter
