Link Failure Reflection

•
•
•
•
In some topologies, link failure on one port must be reflected to the related port to allow the higher layer
redundancy protocol in the network to detect the failure and function correctly.
The link failure-reflection command determines the behavior of the system when there is a link
problem. The link failure-reflection command enables reflection of a link failure. Use the [no] form of
this command to disable failure reflection on the link.
The default value is disabled.

Enabling and Disabling Link Failure Reflection on All Ports
•
•
•
The link reflection on all ports feature extends the link failure reflection feature. It allows the user to
determine whether all ports should be taken down if a single port link fails.
In certain topologies, when a failure state occurs on one link, the link state must be reflected to all ports
to signal any element using this Cisco SCE platform that the device is in a failure state, and therefore
cannot be used.
In link reflection on all ports mode, all ports of the Cisco SCE platform are forced down and the link
state of the first port is reflected on all the ports.
