Hierarchy Level


Configure options that apply to degraded chassis fabric conditions.


  • action-fpc-restart-disable—Allow the user to disable restarting of the FPCs during healing from a degraded fabric condition. The device can automatically recover from degraded fabric conditions by restarting both the fabric planes and the FPCs. If the action-fpc-restart-disable statement is configured, the healing attempt is limited to restarting the fabric planes only.

    The system will detect a null-route filtering condition and try to heal the system.

  • degraded-fabric-detection-enable—Enable detection of an FPC with degraded fabric.

  • degraded-fpc-bad-plane-threshold number-bad-planes—Configure the number of bad planes that indicate an FPC is degraded.

    Options: number-bad-planes—Number of bad planes.

    Range: The range could vary depending on the platform.

    Default: 4
