MVR for IPv4
– 708 –
mvr immediate-leave
This command causes the switch to immediately remove an interface from a
multicast stream as soon as it receives a leave message for that group. Use the
no
form to restore the default settings.
Syntax

immediate-leave
domain-id
- An independent multicast domain. (Range: 1-5)
by-host-ip
- Specifies that the member port will be deleted only when
there are no hosts joining this group.
Default Setting
Disabled
Command Mode
Interface Configuration (Ethernet, Port Channel)
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.
◆
If the “by-host-ip” option is used, the router/querier will not send out a group-
specific query when an IGMPv2/v3 leave message is received (the same as it
would without this option having been used). Instead of immediately deleting
that group, it will look up the record, and only delete the group if there are no
other subscribers for it on the member port. Only when all hosts on that port
leave the group will the member port be deleted.
◆
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
command.
Example
The following enables immediate leave on a receiver port.
Console(config)#interface ethernet 1/5
Console(config-if)#mvr domain 1 immediate-leave
Console(config-if)#
