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 MLDv1/v2 Listener Done 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 mvr6 vlan group command.
Example
The following enables immediate leave on a receiver port.
Console(config)#interface ethernet 1/5
Console(config-if)#mvr6 domain 1 immediate-leave
Console(config-if)#
mvr6 type This command configures an interface as an MVR6 receiver or source port. Use the
no form to restore the default settings.
Syntax
mvr6 domain domain-id type {receiver | source}
no mvr6 domain domain-id type
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. Note that the
source port must be manually configured as a member of the MVR6 VLAN
using the switchport allowed vlan command.
Default Setting
The port type is not defined.
