Mvr Immediate - Edge-Core ES4524M-PoE Management Manual

4
Command Line Interface
• One or more interfaces may be configured as MVR source ports. A source
port is able to both receive and send data for multicast groups which it has
joined through IGMP snooping or which have been statically assigned using
the group keyword.
• 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 a allow a subscriber to dynamically join or
leave an MVR group (see ip igmp snooping on page 4-253). Note that only
IGMPv1/v2 multicast report messages or IGMPv2 leave messages sent by
IGMPv1/v2 hosts are supported by the current MVR standard.
Example
The following configures one source port and several receiver ports on the switch,
enables immediate leave on one of the receiver ports, and statically assigns a
multicast group to another receiver port:
Console(config)#interface ethernet 1/5
Console(config-if)#mvr type source
Console(config-if)#exit
Console(config)#interface ethernet 1/6
Console(config-if)#mvr type receiver
Console(config-if)#mvr immediate
Console(config-if)#exit
Console(config)#interface ethernet 1/7
Console(config-if)#mvr type receiver
Console(config-if)#mvr group 225.0.0.5

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.

Command Usage
• This option only applies to an interface configured as an MVR receiver (see
the mvr interface command on page 4-263).
• 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
