Link Failure Reflection
When recovering from the failure state, the forced down ports (the other link) are brought up only after
the first failed port (link) has recovered. In addition, the reflection algorithm will not try to reflect failure
for this link again for the next 15 seconds, to avoid link stability problems on auto-negotiation.

The following options are available:

The default value is disabled.

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 Cisco SCE platform differently,
depending on different failure conditions, as follows:

The on-all-ports keyword enables reflection of a link failure to all ports.
Use the no form of this command to disable failure reflection to all ports (the on-all-ports keyword
is not used in the no form of the command).

One interface of the Cisco SCE 8000 is down: Link failure is reflected to the all other Cisco SCE
platform ports.
Two reciprocal ports of the Cisco SCE 8000 are down simultaneously, indicating a possible problem
in the linecard of the router to which the Cisco 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 Cisco SCE platform
to continue functioning without interruption.
