Configuring IGMP Snooping Mapping
Multicast TV allows subscribers to join the same Multicast stream, even if the
subscribers are not members of the same VLAN, eliminating television traffic
duplication. IGMP snooping is supported for those transmissions.
Ports which receive Multicast Transmissions, or
Receiver Ports , can be defined in
any VLAN, and not just in the Multicast VLAN. Receiver ports can only receive
Multicast transmissions, they cannot initiate a Multicast TV transmission.
Multicast TV source ports must be a Multicast VLAN members.
IGMP messages are used to indicate which ports are requesting to join or leave
the Multicast group. The
Multicast TV VLAN-IGMP Snooping Mapping Page allows
network managers to map IGMP snooping to VLANs.
To define IGMP Snooping mapping:
STEP 1 Click Bridging > Multicast > Multicast TV VLAN-IGMP Snooping Mapping. The
Multicast TV VLAN-IGMP Snooping Mapping Page opens:
Multicast TV VLAN-IGMP Snooping Mapping Page
The
Multicast TV VLAN-IGMP Snooping Mapping Page contains the following
fields:
• VLAN — Indicates the Multicast TV VLAN for which the IGMP Snooping
mapping is enabled.
