Command Usage
◆
Immediate leave applies only to receiver ports. When enabled, the receiver port
is immediately removed from the multicast group identified in the leave
message. When immediate leave is disabled, the switch follows the standard
rules by sending a group-specific query to the receiver port and waiting for a
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 only 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 with the
mvr vlan group command.
Example
The following enables immediate leave on a receiver port.
Console(config)#interface ethernet 1/5
Console(config-if)#mvr immediate
Console(config-if)#
mvr type
This command configures an interface as an MVR receiver or source port. Use the
no form to restore the default settings.
Syntax
[ no ] mvr type { receiver | source }
receiver - Configures the interface as a subscriber port that can receive
multicast data.
source - Configures the interface as an uplink port that can send and
receive multicast data for the configured multicast groups.
Default Setting
The port type is not defined.
Command Mode
Interface Configuration (Ethernet)
Command Usage
◆
A port which is not configured as an MVR receiver or source port can use IGMP
snooping to join or leave multicast groups using the standard rules for
multicast filtering.
