Multicast VLAN
This chapter describes the
Multicast VLAN
screens.
22.1 Multicast VLAN Overview
Multicast VLAN allows one single multicast VLAN to be shared among different subscriber
VLANs on the network. This improves bandwidth utilization by reducing multicast traffic in
the subscriber VLANs and simplifies multicast group management.
When the IES-1248 forwards traffic to a subscriber port, it tries to forward traffic to a normal
PVC with the same VLAN ID. If this PVC does not exist, the IES-1248 uses the super channel
instead. This applies to all downstream traffic, not just multicast traffic.
It is suggested to use a super channel for multicast VLAN. If a normal PVC is used and the
multicast VLAN ID is not the same as the PVC’s VID, the IES-1248 does not forward traffic
to this PVC even if the subscriber’s port has joined the multicast VLAN.
Since the IES-1248 might change the subscriber’s VLAN ID to the multicast VLAN ID, both
the subscriber’s port and the Ethernet port should join the multicast VLAN.
