Too many broadcast, multicast or unicast packets received on a port may
cause storm and thus slow network and increase timeout. Protocol stack
implementation errors or wrong network configuration may also lead to
such storms.
A device can implement the storm suppression to a broadcast, a
multicast, or a unicast storm respectively. When excessive broadcast,
multicast or unknown unicast packets are received, the switch temporarily
prohibits forwarding of relevant types of packets till data streams are
recovered to the normal state (then packets will be forwarded normally).
Use show storm-control to display configuration.
The following example enables the multicast storm suppression on
GigabitEthernet 1/1 and sets the allowed rate to 4M.
DES-7210# configure terminal
DES-7210(config)# interface GigabitEthernet 1/1
DES-7210(config-if)# storm-control multicast 4096
DES-7210(config-if)# end
Command
show storm-control
