◆ 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
MVR Domain Settings” on page 506).
2. Set the interfaces that will join the MVR as source ports or receiver ports
(see “Configuring MVR Interface Status” on page 510).
3. 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 MVR Multicast Groups to
Interfaces” on page 512).
◆ Although MVR operates on the underlying mechanism of IGMP snooping, the
two features operate independently of each other. One can be enabled or
disabled without affecting the behavior of the other. However, if IGMP
snooping and MVR are both enabled, MVR reacts only to join and leave
messages from multicast groups configured under MVR. Join and leave
messages from all other multicast groups are managed by IGMP snooping.
Also, note that only IGMP version 2 or 3 hosts can issue multicast join or leave
messages. If MVR must be configured for an IGMP version 1 host, the multicast
groups must be statically assigned (see “Assigning Static MVR Multicast Groups
to Interfaces” on page 512).
