About the Link Mode
The SCE platform has an internal hardware card used to maintain the links even when the SCE platform
fails. This hardware card has three possible modes of operation:
• bypass
• forwarding
• cutoff
Normally, the link mode is selected by the SCE platform software according to the configured
connection-mode. However, the link mode command can be used to enforce a specific desired mode.
This may be useful when debugging the network, or in cases where we would like the SCE platform just
to forward the traffic.
Note This is only relevant to inline topologies even though the configuration is available also when in
receive-only mode.)
Options
The following link mode options are available:
• Forwarding — forwards traffic to the SCE platform for processing.
• Bypass — stops all forwarding of traffic to the SCE platform. Traffic still flows through the SCE
platform, but is not processed by it in any way.
This does not affect the redundancy states.
• Cutoff — completely cuts off flow of traffic through the SCE platform.
Recommendations and restrictions
The following recommendations and restrictions:
• For the Cisco SCE8000 platform, the link mode setting is global, and cannot be set for each link
separately. Therefore the all-links keyword must be used.
