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 Table 21) of the link
speed, the switch discards the broadcast traffic until the traffic returns to the low threshold
percentage or less. The full implementation is depicted in the table below.
