Disabling an FPC with Degraded Fabric Bandwidth
You can bring an FPC with degraded fabric bandwidth offline
to avoid causing a null route in the chassis for an extended time.
To configure the option to disable an FPC with degraded bandwidth,
use the offline-on-fabric-bandwidth-reduction statement
at the [edit chassis fpc slot-number] hierarchy level:
[edit chassis]
fpc slot-number {
offine-on-fabric-bandwidth-reduction;
}
The fabric manager checks the number of current active planes periodically. If the number of active planes is lower than the required number of active planes for a particular router, the system waits 10 seconds before it takes any corrective action. If the reduced bandwidth condition persists for an FPC and if this feature has been configured for the FPC, the system brings the FPC offline.
