Global Configuration
C OMMAND U SAGE
MVR source ports can be configured as members of the MVR VLAN using
the switchport allowed vlan command and switchport native vlan
command, but MVR receiver ports should not be statically configured as
members of this VLAN.
E XAMPLE
The following example sets the MVR VLAN to VLAN 1:
Console(config)#mvr6 domain 1 vlan 1
Console(config)#
mvr6 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.
S YNTAX
[no] mvr6 domain domain-id immediate-leave
domain-id - An independent multicast domain. (Range: 1-5)

◆ 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 mvr6 vlan group command.
