COMMAND USAGE
â—† 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 422).
2. Set the interfaces that will join the MVR as source ports or receiver
ports (see "Configuring MVR Interface Status" on page 424).
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 Multicast
Groups to Interfaces" on page 427).
â—† 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.
