Configuring and Managing VLANs 89

You assign a user to a VLAN by setting one of the following attributes on the RADIUS servers or in the local user database:

„Tunnel-Private-Group-ID— This attribute is described in RFC 2868, RADIUS Attributes for Tunnel Protocol Support.

„VLAN-Name— This attribute is a 3Com vendor-specific attribute (VSA).

You cannot configure the Tunnel-Private-Group-ID attribute in the local user database.

Specify the VLAN name, not the VLAN number. The examples in this chapter assume the VLAN is assigned on a RADIUS server with either of the valid attributes. (For more information, see Chapter 21, “Configuring AAA for Network Users,” on page 433.)

VLAN Names

To create a VLAN, you must assign a name to it. VLAN names must be globally unique across a Mobility Domain to ensure the intended user connectivity as determined through authentication and authorization.

Every VLAN on a WX switch has both a VLAN name, used for authorization purposes, and a VLAN number. VLAN numbers can vary uniquely for each WX switch and are not related to 802.1Q tag values.

You cannot use a number as the first character in a VLAN name.

Roaming and VLANs

WX switches in a Mobility Domain contain a user’s traffic within the VLAN that the user is assigned to. For example, if you assign a user to VLAN red, the WX switches in the Mobility Domain contain the user’s traffic within VLAN red configured on the switches.

The WX switch through which a user is authenticated is not required to be a member of the VLAN the user is assigned to. You are not required to configure the VLAN on all WX switches in the Mobility Domain. When a user roams to a switch that is not a member of the VLAN the user is assigned to, the switch can tunnel traffic for the user through another switch that is a member of the VLAN. The traffic can be of any protocol type. (For more information about Mobility Domains, see Chapter 8, “Configuring and Managing Mobility Domain Roaming,” on page 153.)
