mvr immediate
This command causes the switch to immediately removes 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
[no] mvr immediate
Default Setting
Disabled.
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
• This option only applies to an interface configured as an MVR
receiver (see the mvr interface command on page 35-26).
• 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 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.
- The immediate leave command applies to all MVR domains.
Example
The following enables immediate leave on a receiver port.
Console(config)#interface ethernet 1/5
Console(config-if)#mvr immediate
Console(config-if)#
