Syntax

    action (log-only | restart | offline | restart-then-offline);
    no-fabric-switchover;
    percentage (1-99);

Description

Configure a FPC to take a specific action once bandwidth degradation reaches a certain percentage to avoid causing a null route in the chassis.

Note:

This configuration statement is mutually exclusive with the offline-on-fabric-bandwidth-reduction statement. If both statements are configured, the commit check fails and returns an error.

Note:

MX Series devices will count fabric planes in the offline or fault state as part of the bandwidth degradation percentage calculation. On PTX Series devices, when a fabric plane is offline it won't be counted in the bandwidth degradation percentage calculation.

Options

log-only

A message gets logged in the chassisd and message files when the fabric degradation threshold is reached. No other actions are taken.

restart

The FPC with a degraded fabric plane is restarted once the threshold is reached.

offline

The FPC with a degraded fabric plane is taken offline once the threshold is reached. The FPC requires manual intervention to be brought back online. This is the default action if no action attribute configured.

restart-then-offline

The FPC with a degraded fabric plane is restarted once the threshold is reached, and if fabric plane degradation is detected again within 10 minutes, the FPC is taken offline. The FPC requires manual intervention to be brought back online.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 15.1.
