General Configuration Guidelines for MVR:
1.
Enable MVR for a domain on the switch, and select the MVR VLAN (see
“Configuring MVR Domain Settings” on page 558 ).
2.
Create an MVR profile by specifying the multicast groups that will
stream traffic to attached hosts, and assign the profile to an MVR
domain (see “Configuring MVR Group Address Profiles” on page 560 ).
3.
Set the interfaces that will join the MVR as source ports or receiver
ports (see
“Configuring MVR Interface Status” on page 562 ).
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 MVR Multicast Groups
to Interfaces” on page 565 ).
•
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. Since IGMP version 1
hosts do not support leave messages, they are timed out by the switch.
