Configuring the Connection
In link reflection on all ports mode, all ports of the SCE platform are forced down and the link state of
the first port is reflected on all the ports.
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.
Options
The following options are available:
•
•
The default value is disabled.
How to Enable Link Failure Reflection on All Ports
From the SCE(configif)# prompt, type link failure-reflection on-all-ports and press Enter.
Step 1
Enables failure reflection to all ports.
How to Disable Link Failure Reflection on All Ports
From the SCE(config if)# prompt, type no link failure-reflection and press Enter.
Step 1
Disables failure reflection to all ports.
Configuring Link Failure Reflection in Linecard-Aware Mode (SCE 2000 only)
•
•
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 of the SCE 2000 platform are connected to the same linecard in
the router.
OL-7827-12
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).
