Configuring a Host Statically to Join a Group
Hosts or Layer 2 ports normally join multicast groups dynamically, but you can also statically configure
a host on an interface.
Beginning in privileged EXEC mode, follow these steps to add a Layer 2 port as a member of a multicast
group:
To remove the Layer 2 port from the multicast group, use the no ip igmp snooping vlan vlan-id static
mac-address interface interface-id global configuration command.
This example shows how to statically configure a host on an interface and verify the configuration:
Switch# configure terminal
Switch(config)# ip igmp snooping vlan 1 static 224.1.2.3 interface gigabitethernet1/0/1
Switch(config)# end
Switch# show ip igmp snooping multicast
Vlan Group Address Type Ports
---- ------------- ---- -----
1 224.1.2.3 USER Gi1/0/1
Command Purpose
Step 1
configure terminal Enter global configuration mode
Step 2
ip igmp snooping vlan vlan-id static ip_address
interface interface-id
Statically configure a Layer 2 port as a member of a multicast
group:
• vlan-id is the multicast group VLAN ID.
• ip-address is the group IP address.
• interface-id is the member port. It can be a physical
interface or port channel (1 to 12).
Step 3
end Return to privileged EXEC mode.
Step 4
show ip igmp snooping multicast Verify the member port and the IP address.
Step 5
copy running-config startup-config (Optional) Save your entries in the configuration file.
