Command Reference Guide – Multicast Chapter 4 IGMP Configuration Commands
4-7
vlan-id: Specifies the ID for the VLAN to which the port belongs.
Description
Use the igmp group-policy vlan command to set the filter of multicast groups on a
port to control the access to the IP multicast groups.
Use the undo igmp group-policy vlan command to remove the configured filter.
By default, no filter is configured, that is, a host can join any multicast group.
This command has the same function with the igmp group-policy command. Note
that the configured port must belong to the specified VLAN, and the IGMP protocol
must be enabled on this port; otherwise, the configuration does not function.
Related command: igmp group-policy, igmp host-join vlan, and igmp host-join
port.
Example
# Configure that only the hosts matching ACL 2000 rules on Ethernet1/0/1 in
VLAN-interface10 can be added to the multicast group.
