Release Information

Statement introduced in Junos OS Release 9.6.

Hierarchy level [edit forwarding-options] introduced in Junos OS Release 13.2X50-D10. (See Using the Enhanced Layer 2 Software CLI for information about ELS.)

Description

Logically shut down or temporarily disable interfaces when the storm control level is exceeded.

To configure the shutdown action so that the interfaces are disabled temporarily, and recover automatically after a specified period of time:

  • (MX Series, QFX Series, and EX switches that support ELS) Configure both the action-shutdown and the recovery-timeout statements. The interfaces recover automatically when the recovery timeout expires.

  • (EX switches that do not support ELS) Configure both the action-shutdown and the port-error-disable statements. The interfaces recover automatically when the disable timeout expires. (The port-error-disable statement is not supported on QFX Series switches or MX Series routers.)

If you configure the action-shutdown statement without configuring either the port-error-disable or recovery-timeout statement, the interfaces that are enabled for storm control are shut down when the storm control level is exceeded and they do not recover automatically from that port-error condition.

If you do not configure the switch for autorecovery from the disabled condition, you can bring up the disabled interfaces by running one of the following commands:

Note

On EX4300 switches, action-shutdown causes an interface to stop learning MAC addresses and it also drops all incoming packets, but does not disable the physical interface.

Default

The action-shutdown option is not enabled by default. The switching device drops packets for the controlled traffic types if the ingress rate of the combined traffic streams exceeds the specified storm control level. Depending upon the configuration, applicable traffic could include broadcast, unknown unicast, and multicast traffic.
