CHAPTER 9
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.
9.1.1 What You Can Do
• Use the VLAN Status screen (Section 9.2 on page 109) to view and search all VLAN groups.
• Use the VLAN Detail screen (Section 9.2.1 on page 110) to view detailed port settings and status of the
VLAN group.
• Use the Static VLAN screen (Section 9.5 on page 113) to configure and view 802.1Q VLAN parameters
for the Switch.
• Use the VLAN Port Setting screen (Section 9.6 on page 116) to configure the static VLAN (IEEE 802.1Q)
settings on a port.
• Use the Subnet Based VLAN screen (Section 9.7 on page 118) to set up VLANs that allow you to group
traffic into logical VLANs based on the source IP subnet you specify.
• Use the Protocol Based VLAN screen (Section 9.8 on page 121) to set up VLANs that allow you to
group traffic into logical VLANs based on the protocol you specify.
• Use the Voice VLAN screen (Section 9.9 on page 123) to set up VLANs that allow you to group voice
traffic with defined priority and enable the switch port to carry the voice traffic separately from data
traffic to ensure the sound quality does not deteriorate.
• Use the MAC Based VLAN screen (Section 9.10 on page 125) to set up VLANs that allow you to group
untagged packets into logical VLANs based on the source MAC address of the packet. This
eliminates the need to reconfigure the switch when you change ports. The switch will forward the
packets based on the source MAC address you setup previously.
• Use the Port-Based VLAN screen (Section 9.11 on page 126) to set up VLANs where the packet
forwarding decision is based on the destination MAC address and its associated port.
9.1.2 What 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 field of the Ethernet frame) and two bytes of TCI (Tag
Control Information, starts after the source address field of the Ethernet frame).
