Setting Description Factory Default

VID range from 1

to 4094

This field will be active only when selecting the Trunk

port type. Set the VLAN IDs that will not be supported

by this trunk port. Use commas to separate different

VLAN Table

In 802.1Q VLAN table, you can review the VLAN groups that were created, Joined Access Ports,

and Trunk Ports, and in Port-based VLAN table, you can review the VLAN group and Joined port.

NOTE The physical network can have a maximum of 64 VLAN settings.

Using Multicast Filtering

Multicast filtering improves the performance of networks that carry multicast traffic. This section

explains multicasts, multicast filtering, and how multicast filtering can be implemented on your

PT-7728.

The Concept of Multicast Filtering

What is an IP Multicast?

A multicast is a packet sent by one host to multiple hosts. Only those hosts that belong to a

specific multicast group will receive the multicast. If the network is set up correctly, a multicast

can only be sent to an end-station or a subset of end-stations on a LAN or VLAN that belong to the

multicast group. Multicast group members can be distributed across multiple subnets, so that

multicast transmissions can occur within a campus LAN or over a WAN. In addition, networks

that support IP multicast send only one copy of the desired information across the network until

the delivery path that reaches group members diverges. To make more efficient use of network

bandwidth, it is only at these points that multicast packets are duplicated and forwarded. A

multicast packet has a multicast group address in the destination address field of the packet’s IP

header.
