R21xx-HP FlexFabric 11900 IP Multicast Command Reference

26
Parameters
vlan vlan-list: Specifies a space-separated list of up to ten VLAN items. Each item specifies a VLAN by
its ID or a range of VLANs in the form of start-vlan-id to end-vlan-id. The VLAN ID is in the range of 1 to
4094. If this option is not specified, this command takes effect for all VLANs.
Usage guidelines
This command is effective for the multicast groups that a port joins dynamically. If you configure the port
as a static member port for a multicast group, this command is not effective for the multicast group.
The global configuration is effective on all ports, but has a lower priority than the configuration made on
a specific port.
