2.2.4 Configuring Hosts to Statically Join a Group
Hosts or Layer 2 ports normally join multicast groups dynamically, but you can also
configure hosts to statically join a group.
Follow these steps to configure hosts to statically join a group:
Step 1 configure
Enter global configuration mode.
Step 2 ip igmp snooping vlan-config
vlan-id-list
static
ip
interface { fastEthernet
port-list
|
gigabitEthernet
port-list
| ten-gigabitEthernet
port-list
| port-channel
lag-list
}
vlan-id-list:
Specify the ID or the ID list of the VLAN(s).
ip:
Specify the IP address of the multicast group that the hosts want to join.
port-list
/
lag-list:
Specify the ports that is connected to the hosts. These ports will become
static member ports of the group.
Step 3 show ip igmp snooping groups static
Show the static MLD Snooping configuration.
Step 4 end
Return to privileged EXEC mode.
Step 5 copy running-config startup-config
Save the settings in the configuration file.
The following example shows how to configure port 1/0/1-3 in VLAN 2 to statically join the
multicast group 239.1.2.3:
