Command
Description
mvr type
Sets the MVR port type.
mvr group
Statically sets a port to receive multicast traffic sent to the IP multicast
address.
mvr immediate
Enables the Immediate Leave state on a port.
no mvr
Disables the MVR on the configured port.
Setting the MVR Port Type
The
mvr type
command, in Interface Configuration mode, sets the MVR port type. The type can
be either receiver port or source port.
The
source
port is a port to which the source of the multicast traffic is connected. Subscribers
cannot be directly connected to source ports. All source ports belong to the single multicast VLAN.
The
receiver
port represents a port to which a subscriber is connected. The receiver port is a
member of a VLAN other than the multicast (MVR) VLAN. After sending an IGMP Join message,
the subscriber starts receiving the multicast data, and after sending a Leave message, the subscriber
stops receiving the multicast data.
NOTE
The receiver ports should be added to the MVR VLAN as untagged members and
the default VLAN (PVID) of the receiver port should be different.
