About VLAN Assignments
A client is assigned to a VLAN by one of several methods. There is an order of precedence by which VLANs are
assigned. The assignment of VLANs are (from lowest to highest precedence):
1. The default VLAN is the VLAN configured for the WLAN (see “Virtual APs” on page105).
2. Before client authentication, the VLAN can be derived from rules based on client attributes (SSID, BSSID,
client MAC, location, and encryption type). A rule that derives a specific VLAN takes precedence over a rule
that derives a user role that may have a VLAN configured for it.
3. After client authentication, the VLAN can be the VLAN configured for a default role for an authentication
method, such as 802.1x or VPN.
4. After client authentication, the VLAN can be derived from attributes returned by the authentication server
(server-derived rule). A rule that derives a specific VLAN takes precedence over a rule that derives a user role
that may have a VLAN configured for it.
5. After client authentication, the VLAN can be derived from Microsoft Tunnel attributes (Tunnel-Type,
Tunnel Medium Type, and Tunnel Private Group ID). All three attributes must be present. This does not
require any server-derived rule.
6. After client authentication, the VLAN can be derived from Vendor Specific Attributes (VSA) for RADIUS
server authentication. This does not require any server-derived rule. If a VSA is present, it overrides any
previous VLAN assignment.
Assigning a Static Address to a VLAN
You can manually assign a static IP address to a VLAN on the controller. At least one VLAN on the controller
must be assigned a static IP address.
Using the WebUI
1. Navigate to the Configuration > Network > IP > IP Interfaces page on the WebUI. Click Edit for the
VLAN you just added.
2. Select the Use the following IP address option. Enter the IP address and network mask of the VLAN interface.
If required, you can also configure the address of the DHCP server for the VLAN by clicking Add.
3. Click Apply.
Using CLI
interface vlan <id>
ip address <address> <netmask>
Configuring a VLAN to Receive a Dynamic Address
A VLAN on the controller obtains its IP address in one of the following ways:
z Manually configured by the network administrator. This is the default method and is described in “Assigning
a Static Address to a VLAN” on page60. At least one VLAN on the controller must be assigned a static IP
address.
