Configuring Port Storm Control
A traffic storm occurs when packets flood the LAN, creating excessive load and degrading network performance. When enabled, port storm control discards the excess unicast, multicast, or broadcast traffic that is detected on a port.
Use the port-storm-control-modify command to modify the percentage of total available bandwidth that can be used by broadcast, multicast, or unicast traffic.
CLI (network-admin@switch) > port-storm-control-modify
|
port-storm-control-modify |
Modify port storm control configuration. |
|
port port-list |
Specify a single port or a list of ports. |
|
unknown-ucast-level unknown-ucast-level-string |
Specify the bandwidth to be allotted for unknown unicast as a percentage of the port link speed. The default is 30%. |
|
unknown-mcast-level unknown-mcast-level-string |
Specify the bandwidth to be allotted for unknown multicast as a percentage of the port link speed. The default is 30%. |
|
broadcast-level broadcast-level-string |
Specify the bandwidth to be allotted for broadcast as a percentage of the port link speed. The default is 30%. |
To set the available bandwidth for broadcast traffic to 10% of port link speed on port 5, use the command:
CLI (network-admin@switch) > port-storm-control-modify port 5 broadcast-level 10
Use the port-storm-control-show command to display the configuration:
CLI (network-admin@switch) > port-storm-control-show
switch port speed unknown-ucast-level unknown-mcast-level broadcast-level

This setting discards broadcast traffic if it exceeds 10% of the link speed on port 5.
