Multicast Filtering Commands
4-395
4
• The IP address range from 224.0.0.0 to 239.255.255.255 is used for multicast
streams. MVR group addresses cannot fall within the reserved IP multicast
address range of 224.0.0.x.
• IGMP snooping must be enabled to allow a subscriber to dynamically join or
leave an MVR group (see ip igmp snooping on page 4-375). Note that only
IGMP version 2 or 3 hosts can issue multicast join or leave messages.
Example
The following configures one source port and several receiver ports on the switch,
statically assigns a multicast group to a receiver port using the MVR VLAN, and then
statically assigns an MVR receiver group to the MVR receiver VLAN:
mvr immediate
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 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 4-394).
• 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.
