The following is an example of the CLI commands:
Storm Control
When Broadcast, Multicast, or Unknown Unicast frames are received, they
are duplicated, and a copy is sent to all possible egress ports. This means that
in practice, they are sent to all ports belonging to the relevant VLAN. In this
way, one ingress frame is turned into many, creating the potential for a storm.
Storm protection provides the ability to limit the number of frames entering
the switch, and to define the types of frames that are counted towards this
limit.
When a threshold (limit) is configured on the device, the port discards traffic
when that threshold is reached. The port remains blocked until the traffic rate
drops below this threshold. It then resumes normal forwarding.
To configure Storm Control:
1
Click Switching > Ports > Storm Control in the tree view to display the
Storm Control: Summary page.
Storm control parameters are displayed for all ports.
2 To configure Storm Control on a port, click Edit.
