Multicast Vlan - ZyXEL Communications MSC1000G User Manual

Link Aggregation Control Protocol (LACP)
The MSC supports the link aggregation IEEE 802.3ad protocol. Link aggregation (trunking) is
the grouping of physical ports into one logical higher-capacity link. You may want to trunk
ports if for example, it is cheaper to use multiple lower-speed links than to under-utilize a
high-speed, but more costly, single-port link.
IEEE 802.1Q Tagged VLAN
Your management switch card uses the IEEE 802.1Q Tagged VLAN (Virtual Local Area
Network), which allows your device to deliver tagged/untagged frames to and from its ports.

Multicast VLAN

Multicast VLAN is designed for applications (such as Media-on-Demand (MoD)) using
multicast traffic across an Ethernet ring-based service provider network. 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.
Transparent LAN Service (TLS)
Use TLS (also known as VLAN stacking) to add an outer VLAN tag to the inner IEEE 802.1Q
tagged frames that enter the network. By tagging the tagged frames ("double-tagged" frames),
the service provider can manage up to 4,094 VLAN groups with each group containing up to
4,094 customer VLANs. This allows a service provider to provide different services based on
specific VLANs, for many different customers.
PPPoA-to-PPPoE (PAE) PVC
This feature allows the system to translate PPPoA packets to PPPoE packets (and vice versa)
to allow communication between CPE clients and an access concentrator (such as a BRAS)
through the switch.
PPPoE Intermediate Agent Information
Similar to DHCP relay option82, you can set the system to insert line information into client
PPPoE Discover Initialization (PODI) packets. This allows a PPPoE termination server to
identify and authenticate a PPPoE client.
IEEE 802.1p Priority
The system uses IEEE 802.1p priority to assign priority levels to individual PVCs. The system
can also handle multiple IEEE 802.1p priority queues on a single PVC.
