9.2 Storm Control Commands

This section describes commands you use to configure storm control and view storm-
control configuration information. The storm-control feature measures traffic activity on
the physical ports and blocks traffic on the port when the amount of traffic reaches the
threshold. Blocking the port helps maintain network performance.

9.2.1 storm-control broadcast

This command enables broadcast storm recovery mode. If the mode is enabled, broadcast
storm recovery with high and low thresholds is implemented.
The threshold implementation follows a percentage pattern. If the broadcast traffic on any
Ethernet port exceeds the high threshold percentage (as represented in
link speed, the switch discards the broadcasts traffic until the broadcast traffic returns to
the low threshold percentage or less. The full implementation is depicted in
Table 9-1. Broadcast Storm Recovery Thresholds
