9.2.6.3 Source/Receiver Port
You need to specify the source and receiver ports for MVR. The followings are the
definitions for the ports.
• Source Port
This is connected to multicast routers or sources as an uplink port, which receives
and sends the multicast traffic. Subscribers cannot be directly connected to source
ports. All source ports belong to the multicast VLAN as tagged.
• Receiver Port
This is directly connected to subscribers as a subscriber port, which should only re-
ceive the multicast traffic. All receiver ports must belong to the both subscriber and
multicast VLANs as untagged for implementation reasons.
To specify a port as the source or receiver port, use the following command.
mvr port PORTS type {receiver |
source}
Specifies an MVR port.
PORTS: port number
Deletes a specified MVR port.
9.2.6.4 MVR Helper Address
When being in a different network from an MVR group’s, a multicast router sends the
multicast traffic to each MVR group using Layer 3 multicast routing. In such an
environment, when an IGMP packet from a subscriber is transmitted to the multicast
router via the MVR group (multicast VLAN interface), the source address of the IGMP
packet may not match the network address of the MVR group. In this case, the multicast
router normally discards the IGMP packet. To avoid this behavior, you can configure the
switch to replace the source address with a specified helper address. The helper address
must belong to the MVR group’s network.
To specify an MVR helper address to replace a source address of an IGMP packet, use
the following command.
mvr vlan VLAN helper A.B.C.D
Specifies an MVR helper address.
VLAN: VLAN ID (1-4094)
A.B.C.D: helper address
Deletes a specified MVR helper address.
9.2.6.5 Displaying MVR Configuration
To display an MVR configuration, use the following command.
