Configuring Port Storm Control


Port Storm Control prevents traffic on a LAN from disruption by a broadcast, multicast, or unicast storm on a port. A LAN storm occurs when packets flood the LAN, creating excessive traffic and degrading network performance.


Use the port-storm-control-modify to modify the percentage of total available bandwidth that can be used by broadcast, multicast, or unicast traffic.


CLI (network-admin@Leaf1) > port-storm-control-modify port 11 unknown-ucast-level 1.1


Use the port-storm-control-show command to display the configuration:


CLI (network-admin@Leaf1) > port-storm-control-show


switch   port speed unknown-ucast-level unknown-mcast-level broadcast-level    vlag           trunk
