fault-finder multicast-storm

switch(config)# fault-finder multicast-storm
action                Configure the action taken when a fault is detected.
[ethernet] PORT-LIST  The ports on which to enable Multicast Storm Control.
sensitivity           Configure the fault sensitivity level.

switch(config)# fault-finder multicast-storm ethernet
PORT-LIST             Enter a port number, a list of ports or 'all' for all
                    ports.

switch(config)# fault-finder multicast-storm ethernet 1/1
action                Configure the action taken when a multicast storm is
                    detected.

switch(config)# fault-finder multicast-storm ethernet 1/1 action
warn                  Log an event only.
warn-and-disable      Log an event and disable the port.

switch(config)# fault-finder multicast-storm ethernet 1/1 action warn-and-disable

SECONDS               Configure the number of seconds for which the port
                    remains disabled. A value of 0 means that the port will
                    remain disabled until manually re-enabled.

switch(config)# fault-finder multicast-storm ethernet 1/1 action warn-and-disable 10

percent               Configure the number of inbound multicast packets per
                    second that is considered a multicast storm. This
                    threshold is computed assuming a size of 64 bytes per
                    incoming multicast packet.
pps                   Configure the number of inbound multicast packets per
                    second that is considered a multicast storm.

switch(config)# fault-finder multicast-storm ethernet 1/1 action warn-and-disable 10 percent

<1-100>               The percentage that is considered a multicast storm.
