Source/Receiver Port
You need to specify the source and receiver ports for MVR. The followings are the defini-
tions 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.
Command
mvr port PORTS type { receiver |
source }
no mvr port PORTS
MVR Helper Address
When being in a different network from an MVR group's, a multicast router sends the mul-
ticast traffic to each MVR group. In such an environment, when an IGMP packet from a
subscriber is transmitted to the multicast router via the MVR group (multicast VLAN inter-
face), 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.
Command
mvr vlan VLAN helper A.B.C.D
no mvr vlan VLAN helper
