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 Tabl e 1) of the 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 the Table 1.
