Disabling FPC Restart
You can disable FPC restart to limit recovery actions from a degraded fabric condition. On T640 and T1600 routers, only the fabric plane is restarted. On PTX Series systems, only the Switch Interface Boards (SIBs) are restarted. To disable the restarting of FPCs, use the action-fpc-restart-disable statement at the [edit chassis fabric degraded] hierarchy level:
[edit chassis fabric] degraded { action-fpc-restart-disable; }
Whenever FPC restart is disabled, an alarm is raised when there are unreachable destinations present in the router, and you must restart the FPCs manually.
To ensure that both the fabric planes (T640 and T1600 routers) or the SIBs (PTX Series systems) and the FPCs are restarted during the recovery process, do not configure the action-fpc-restart-disable statement at the [edit chassis fabric degraded] hierarchy level.
