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
[no] mvr [domain domain-id] immediate-leave
domain-id - An independent multicast domain. (Range: 1-5)
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.
• 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 domain 1 immediate-leave
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 [domain domain-id] type {receiver | source}
domain-id - An independent multicast domain. (Range: 1-5)
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.
