COMMAND USAGE
â—† General Configuration Guidelines for MVR:
1. Enable MVR globally on the switch, and select the MVR VLAN.
2. Set the interfaces that will join the MVR as source ports or receiver
ports.
3. If you are sure that only one subscriber attached to an interface is
receiving multicast services, you can enable the immediate leave
function.
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 leave messages. Immediate leave therefore
cannot be used for IGMP version 1 clients.
PARAMETERS
