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
