Link Failure Reflection
Configuring Link Failure Reflection in Linecard-Aware Mode
• How to Enable Linecard-Aware Mode, page 7-8
• How to Disable Linecard-Aware Mode, page 7-8
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
Step 1 From the SCE(config if)# prompt, type link failure-reflection on-all-ports linecard-aware-mode and
press Enter.
Enables failure reflection to all ports with linecard aware mode.
How to Disable Linecard-Aware Mode
Step 1 From the SCE(config if)# prompt, type no link failure-reflection linecard-aware-mode and press
Enter.
Disables linecard aware mode.
Note This command does not disable link failure reflection on all ports.
