Configuring A Host Statically To Join A Group - Cisco Catalyst 2950 Software Configuration Manual

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 [vlan vlan-id]
Step 5
show ip igmp snooping mrouter [vlan vlan-id]
Step 6 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 and verify the configuration:
Switch# configure terminal
Switch(config)# ip igmp snooping vlan 200 mrouter interface gigabitethernet0/2
Switch(config)# end
Switch# show ip igmp snooping mrouter vlan 200

Configuring a Host Statically to Join a Group

Ports normally join multicast groups through the IGMP report message, but you can also statically
configure a host on an interface.
Beginning in privileged EXEC mode, follow these steps to add a port as a member of a multicast group:
Command
Step 1
configure terminal
Step 2
ip igmp snooping vlan vlan-id static
mac-address interface interface-id
Step 3 end

Purpose
Enter global configuration mode.
Specify the multicast router VLAN ID. For vlan-id, the range is
1 to 4094 when the enhanced software image is installed and
1 to 1005 when the standard software image is installed. Do not
enter leading zeros.
Specify the interface to the multicast router.
Return to privileged EXEC mode.
Verify that IGMP snooping is enabled on the VLAN interface.
Display information on dynamically learned and manually
configured multicast router interfaces.
(Optional) Save your entries in the configuration file.

Gi0/2(static)
Purpose
Enter global configuration mode
Statically configure a port as a member of a multicast group:
• vlan-id is the multicast group VLAN ID.
• mac-address is the group MAC address.
• interface-id is the member port.
Return to privileged EXEC mode.
