Configuration Guide 326
Configuring Layer 2 Multicast Configuring MLD Snooping
The following example shows how to enable Fast Leave on port 1/0/3:
Switch#configure
Switch(config)#ipv6 mld snooping
Switch(config)#interface gigabitEternet 1/0/3
Switch(config-if)#ipv6 mld snooping
Switch(config-if)#ipv6 mld snooping immediate-leave
Switch(config-if)#show ipv6 mld snooping interface gigabitEthernet 1/0/3 basic-config
Port MLD-Snooping Fast-Leave
---- ------------- ----------
Gi1/0/3 enable enable
Switch(config-if)#end
Switch#copy running-config startup-config
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
| 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
]] 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.
