Configuring IGMP Snooping
Beginning in privileged EXEC mode, follow these steps to enable a static connection to a multicast
router:
Command
Step 1
configure terminal
Step 2
ip igmp snooping vlan vlan-id mrouter
interface interface-id
Step 3
end
Step 4
show ip igmp snooping mrouter [vlan vlan-id] Verify that IGMP snooping is enabled on the VLAN interface.
Step 5
copy running-config startup-config
To remove a multicast router port from the VLAN, use the no ip igmp snooping vlan vlan-id mrouter
interface interface-id global configuration command.
This example shows how to enable a static connection to a multicast router:
Switch# configure terminal
Switch(config)# ip igmp snooping vlan 200 mrouter interface gigabitethernet0/2
Switch(config)# end
Configuring a Blade Server Statically to Join a Group
Blade servers that are connected to Layer 2 ports normally join multicast groups dynamically. You can
also statically configure a Layer 2 port, to which a blade server is connected, so that the port joins a
multicast group.
Beginning in privileged EXEC mode, follow these steps to add a Layer 2 port as a member of a multicast
group:
Command
Step 1
configure terminal
Step 2
ip igmp snooping vlan vlan-id static ip_address
interface interface-id
Step 3
end
Step 4
show ip igmp snooping groups
Step 5
copy running-config startup-config

Purpose
Enter global configuration mode.
Specify the multicast router VLAN ID and the interface to the
multicast router.
The VLAN ID range is 1 to 1001 and 1006 to 4094.
•
The interface can be a physical interface or a port channel.
•
The port-channel range is 1 to 48.
Return to privileged EXEC mode.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Statically configure a Layer 2 port as a member of a multicast
group:
vlan-id is the multicast group VLAN ID. The range is 1 to
•
1001 and 1006 to 4094.
ip-address is the group IP address.
•
interface-id is the member port. It can be a physical
•
interface or a port channel (1 to 48).
Return to privileged EXEC mode.
Verify the member port and the IP address.
(Optional) Save your entries in the configuration file.
