NOTE
If the queries and the multicast data are received from different ports, configure
the port from which the queries are received as the source port.
Command Syntax
device-name
(config-if
UU/SS/PP
)#
mvr type
{
source
|
receiver
}
Argument Description
source
Sets the port as an uplink port that can receive multicast data for the configured
multicast groups. More than one source port can be defined.
receiver
Sets the port as a subscriber port that can receive multicast data.
Setting an MVR Port IP Multicast Group
The
mvr group
command, in Interface Configuration mode, defines the allowed subset of
multicast groups on the configured interface. This subset is the multicast group IP address that the
port is allowed to join. When the
mvr group
command is used without specifying an IP address,
all groups are allowed to join.
The
no
form of this command, with an IP address specified, disallows the receiver from joining the
specified groups. If no IP address is specified, the no form of this command disallows the receiver
(subscriber) from joining any of the groups.
By default, no IP address will be allowed to join the multicast group.
NOTE
Receiver ports can also dynamically join multicast groups by using IGMP join and
leave messages.
Command Syntax
device-name
(config-if
UU/SS/PP
)#
mvr
group
[
A.B.C.D
]
device-name
(config-if
UU/SS/PP
)#
no mvr
group
[
A.B.C.D
]
Argument Description
A.B.C.D
(Optional). The MVR group IP multicast address.
Setting the MVR Port to Immediate Leave State
The
mvr immediate
command, in Interface Configuration mode, enables the Immediate Leave
state on a port. The
no mvr immediate
command disables the Immediate Leave state.
By default, the Immediate Leave state is enabled on all ports.
