Hierarchy Level

Release Information

Statement introduced in Junos OS Release 9.6 for EX Series switches.

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

Description

Logically shut down or temporarily disable interfaces when the storm control level is exceeded, as follows:

  • If you set both the action-shutdown and the port-error-disable statements, the interfaces are disabled temporarily and recover automatically when the disable timeout expires.
  • If you set both the action-shutdown and the recovery-timeout statements, the interfaces are disabled temporarily and recover automatically when the recovery timeout expires.
  • If you set the action-shutdown statement and do not the specify the port-error-disable 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. You must issue the clear ethernet-switching port-error command to clear the port error and restore the interfaces to service.
  • If you set the action-shutdown statement and do not the specify the 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. You must issue the clear ethernet-switching recovery-timeout command to clear the port error and restore the interfaces to service.

Note: This statement does not shut down interfaces at the link layer. The shutdown is logical only.

Default

The action-shutdown option is not enabled by default. The switch 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.
