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 port-storm-control-modify to modify the percentage of total available bandwidth that can be used by broadcast, multicast, or unicast traffic. However, to configure storm control on trunk ports, use the command, trunk-modify.
CLI network-admin@Leaf1 > port-storm-control-modify port 11 unknown-ucast-level 1.1
CLI network-admin@Leaf1 > trunk-modify port 10
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
