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

 

and IP learning is not possible. In addition to this, tagged frames can-

 

not be routed between VLANs.

 

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

 

Allocate network resources (such as servers) to groups

 

For a more comprehensive explanation of the VLAN concept, refer

 

to the online help.

Warning when using STP

It is important to be aware of problems that may arise when using

 

Spanning Tree and VLANs. The Spanning Tree can use alternative

 

paths (such as different ports) to get messages to their destination.

 

VLANs specify which ports can receive messages (see “Spanning

 

Tree”, p. 55).

 

Warning When using the Spanning Tree facility, use only one

 

VLAN. If you use two or more VLANs, unexpected

 

changes in your network topology may occur.

Policy-based VLANs

The switch or stack uses “Policy-based VLANs”. This means that the

 

devices attached to the switch/stack can be grouped by any combina-

 

tion of MAC address, IP address, IP net and port number; therefore,

 

devices can belong to one or more VLANs.

Policy hierarchy

To avoid conflicts between two VLANs, a strict priority of the poli-

 

cies is used:

 

1. MAC address

 

2. IP address and IP net
