Mode Global Config
Acceptable values are:
100h 100BASE-T half-duplex
100f 100BASE-T full duplex
10h 10BASE-T half duplex
10f 100BASE-T full duplex
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 “Broadcast Storm Recovery
Thresholds” table) 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
“Broadcast Storm Recovery Thresholds” table.

Mode Global Covnfig
no storm-control broadcast
This command disables broadcast storm recovery mode.
The threshold implementation follows a percentage pattern. If the broadcast traffic on any Ethernet
port exceeds the high threshold percentage (as represented in “Broadcast Storm Recovery
Thresholds” table) of the link speed, the switch discards the broadcasts traffic until the broadcast
