mvr source-port-
mode
This command configures the switch to forward only multicast streams that a
source port has dynamically joined or to forward all multicast groups. Use the no
form to restore the default setting.
Syntax
mvr source-port-mode {dynamic | forward}
no mvr source-port-mode
dynamic - Configures source ports to only forward dynamically-joined
MVR group multicast streams.
forward - Configures source ports to always forward MVR groups.
Default Setting
Forwards all multicast streams which have been specified in a profile and bound to
a domain.
Command Mode
Global Configuration
Command Usage
◆ By default, the switch forwards any multicast streams within the address range
set by a profile, and bound to a domain. The multicast streams are sent to all
source ports on the switch and to all receiver ports that have elected to receive
data on that multicast address.
◆ When the mvr source-port-mode dynamic command is used, the switch only
forwards multicast streams which the source port has dynamically joined. In
other words, both the receiver port and source port must subscribe to a
multicast group before a multicast stream is forwarded to any attached client.
Note that the requested streams are still restricted to the address range which
has been specified in a profile and bound to a domain.
Example
Console(config)#mvr source-port-mode dynamic
