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.
