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.
Ruijie# configure terminal
Ruijie(config)# interface GigabitEthernet 1/1
Ruijie(config-if)# storm-control multicast 4096
Ruijie(config-if)# end
