Switch User Manual

In this chapter In this chapter you will learn how to use Advanced Configuration ef-

fectively. This chapter covers the Virtual LAN (VLAN) features.

You can create logical network groups (VLANs) by segmenting the

switch; for example, according to the subnetting scheme within your

network. Each VLAN is an isolated group and the switch only for-

wards traffic between members of the same group. Communication

between groups can be implemented using routers.

Note This switch is able to forward tagged frames from devices

supporting IEEE 802.1p/Q. These frames are only for-

warded to ports that are in the same VLAN.

However, IP policies cannot be used for devices using tagged VLANs

and IP learning is not possible.

VLANs (Virtual LANs)

Purpose You can use VLANs to:

• Create up to 128 separate user groups

• Limit broadcast and multicast traffic

• Increase security by limiting communication between groups
