4 Command Line Interface

response to determine if there are any remaining subscribers for that multicast group before removing the port from the group list.

Using immediate leave can speed up leave latency, but should only be enabled on a port attached to one multicast subscriber to avoid disrupting services to other group members attached to the same interface.

Immediate leave does not apply to multicast groups which have been statically assigned to a port.

IGMP snooping must be enabled to a allow a subscriber to dynamically join or leave an MVR group (see ip igmp snooping on page 4-212). Note that only IGMP version 2 or 3 hosts can issue multicast join or leave messages.

Example

The following configures one source port and several receiver ports on the switch, enables immediate leave on one of the receiver ports, and statically assigns a multicast group to another receiver port:

Console(config)#interface ethernet 1/5

Console(config-if)#mvr type source

Console(config-if)#exit

Console(config)#interface ethernet 1/6

Console(config-if)#mvr type receiver

Console(config-if)#mvr immediate

Console(config-if)#exit

Console(config)#interface ethernet 1/7

Console(config-if)#mvr type receiver

Console(config-if)#mvr group 225.0.0.5

Console(config-if)#

show mvr

This command shows information about the global MVR configuration settings when entered without any keywords, the interfaces attached to the MVR VLAN using the interface keyword, or the multicast groups assigned to the MVR VLAN using the members keyword.
