Configuring Max Group and Overflow Action on the Port
Step 1 configure
Enter global configuration mode.
Step 2 interface {fastEthernet
port
| range fastEthernet
port-list
| gigabitEthernet
port
| range
gigabitEthernet
port-list
| ten-gigabitEthernet
port
| range ten-gigabitEthernet
port-list
| port-
channel
port-channel-id
| range port-channe
port-channel-list
}
Enter interface configuration mode.
Step 3 ipv6 mld snooping max-groups
maxgroup
Enter the number of multicast groups the port can join. The range is 0 to 1000.
Step 4 ipv6 mld snooping max-groups action {drop | replace}
Specify the action towards the new multicast group when the number of multicast groups the
port joined exceeds max group.
drop: Drop all subsequent membership report messages, and the port join no more new
multicast groups.
replace: Replace the existing multicast group with the lowest multicast MAC address with the
new multicast group.
Step 5 show ipv6 mld snooping interface [fastEthernet [
port | port-list
] | gigabitEthernet [
port |
port-list
] |
ten-
gigabitEthernet [
port | port-list
]] max-groups
Show the IGMP group limitation on the specified port(s) or of all the ports.
Step 6 end
Return to privileged EXEC mode.
Step 7 copy running-config startup-config
Save the settings in the configuration file.
The following example shows how to configure the Max Group as 500 and the Overflow
Action as Drop on port 1/0/3:
Switch#configure
Switch(config)#ipv6 mld snooping
Switch(config)#interface ten-gigabitEthernet 1/0/3
Switch(config-if)#ipv6 mld snooping
Switch(config-if)#ipv6 mld snooping max-groups 500
Switch(config-if)#ipv6 mld snooping max-groups action drop
Switch(config-if)#show ipv6 mld snooping interface ten-gigabitEthernet 1/0/3 max-
groups
