VLAN

9.1 Overview

This chapter shows you how to configure 802.1Q tagged and port-based VLANs. The type of screen you see here depends on the VLAN Type you selected in the

Switch Setup screen.

9.1.1What You Can Do

•Use the VLAN Status screen (Section 9.2 on page 97) to view all VLAN groups.

•Use the VLAN Detail screen (Section 9.2.1 on page 98) to view detailed port settings and status of the VLAN group.

•Use the Static VLAN screen (Section 9.3 on page 99) to configure and view 802.1Q VLAN parameters for the Switch.

•Use the VLAN Port Setting screen (Section 9.4 on page 101) to configure the static VLAN (IEEE 802.1Q) settings on a port.

•Use the Subnet Based VLAN screen (Section 9.5 on page 102) to set up VLANs that allow you to group traffic into logical VLANs based on the source IP subnet you specify.

•Use the Port-Based VLAN screen (Section 9.7 on page 108) to set up VLANs where the packet forwarding decision is based on the destination MAC address and its associated port.

9.1.2What You Need to Know

Read this section to know more about VLAN and how to configure the screens.

IEEE 802.1Q Tagged VLANs

A tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identify the VLAN membership of a frame across bridges - they are not confined to the switch on which they were created. The VLANs can be created statically by hand or dynamically through GVRP. The VLAN ID associates a frame with a specific VLAN and provides the information that switches need to process the frame across the network. A tagged frame is four bytes longer than an untagged frame and contains two bytes of TPID (Tag Protocol Identifier, residing within the type/length
