Vlan; Chapter 9 Vlan; Overview; What You Can Do - ZyXEL Communications GS2210 Series User Manual

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
• Use the VLAN Detail screen
of the VLAN group.
• Use the Static VLAN screen
parameters for the Switch.
• Use the VLAN Port Setting screen
802.1Q) settings on a port.
• Use the Subnet Based VLAN screen
to group traffic into logical VLANs based on the source IP subnet you specify.
• Use the Protocol Based VLAN screen
to group traffic into logical VLANs based on the protocol you specify.
• Use the Voice VLAN screen
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
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
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)
