General Configuration Guidelines for MVR
1. Enable MVR globally on the switch, select the MVR VLAN, and add the multicast
groups that will stream traffic to attached hosts (see “Configuring Global MVR
Settings” on page 3-252).
2. Set the interfaces that will join the MVR as source ports or receiver ports (see
“Configuring MVR Interface Status” on page 3-256).
3. Enable IGMP Snooping to a allow a subscriber to dynamically join or leave an
MVR group (see “Configuring IGMP Snooping and Query Parameters” on
page 3-239). Note that only IGMP version 2 or 3 hosts can issue multicast join or
leave messages.
4. For multicast streams that will run for a long term and be associated with a stable
set of hosts, you can statically bind the multicast group to the participating
interfaces (see “Assigning Static Multicast Groups to Interfaces” on page 3-257).
Configuring Global MVR Settings
The global settings for Multicast VLAN Registration (MVR) include enabling or
disabling MVR for the switch, selecting the VLAN that will serve as the sole channel
for common multicast streams supported by the service provider, and assigning the
multicast group address for each of these services to the MVR VLAN.
Command Usage
IGMP snooping and MVR share a maximum number of 255 groups. Any multicast
streams received in excess of this limitation will be flooded to all ports in the
associated VLAN.
