Parameter

Description

Basic Configuration Settings

Virtual AP enable

Select the Virtual AP enable checkbox to enable or disable the virtual AP.

 

 

VLAN

The VLAN(s) into which users are placed in order to obtain an IP address. Click the drop-down

 

list to select a configured VLAN, the click the arrow button to associate that VLAN with the

 

virtual AP profile.

 

 

Forward mode

This parameter controls whether data is tunneled to the controller using generic routing

 

encapsulation (GRE), bridged into the local Ethernet LAN (for remote APs), or a combination

 

thereof depending on the destination (corporate traffic goes to the controller, and Internet

 

access remains local). All forwarding modes support band steering, TSPEC/TCLAS

 

enforcement, 802.11k and station blacklisting.

 

Click the drop-down list to select one of the following forward modes:

 

• Tunnel: The AP handles all 802.11 association requests and responses, but sends all 802.11

 

data packets, action frames and EAPOL frames over a GRE tunnel to the controller for

 

processing. The controller removes or adds the GRE headers, decrypts or encrypts 802.11

 

frames and applies firewall rules to the user traffic as usual. Both remote and campus APs

 

can be configured in tunnel mode.

 

• Bridge: 802.11 frames are bridged into the local Ethernet LAN. When a remote AP or

 

campus AP is in bridge mode, the AP (and not the controller) handles all 802.11 association

 

requests and responses, encryption/decryption processes, and firewall enforcement. The

 

802.11e and 802.11k action frames are also processed by the AP, which then sends out

 

responses as needed.

 

An AP in bridge mode does not support captive portal authentication. Both remote and

 

campus APs can be configured in bridge mode. Note that you must enable the control plane

 

security feature on the controller before you configure campus APs in bridge mode.

 

• Split-Tunnel:802.11 frames are either tunneled or bridged, depending on the destination

 

(corporate traffic goes to the controller, and Internet access remains local).

 

A remote AP in split-tunnel forwarding mode handles all 802.11 association requests and

 

responses, encryption/decryption, and firewall enforcement. the 802.11e and 802.11k action

 

frames are also processed by the remote AP, which then sends out responses as needed.

 

• Decrypt-Tunnel:Both remote and campus APs can be configured in decrypt-tunnel mode.

 

When an AP uses decrypt-tunnel forwarding mode, that AP decrypts and decapsulates all

 

802.11 frames from a client and sends the 802.3 frames through the GRE tunnel to the

 

controller, which then applies firewall policies to the user traffic.

 

When the controller sends traffic to a client, the controller sends 802.3 traffic through the

 

GRE tunnel to the AP, which then converts it to encrypted 802.11 and forwards to the client.

 

This forwarding mode allows a network to utilize the encryption/decryption capacity of the

 

AP while reducing the demand for processing resources on the controller.

 

APs in decrypt-tunnel forwarding mode also manage all 802.11 association requests and

 

responses, and process all 802.11e and 802.11k action frames. APs using decrypt-tunnel

 

mode do have some limitations that not present for APs in regular tunnel forwarding mode.

 

You must enable the control plane security feature on the controller before you configure

 

campus APs in decrypt-tunnel forward mode.

 

NOTE: Virtual APs in bridge or split-tunnel mode using static WEP should use key slots 2-4 on

 

the controller. Key slot 1 should only be used with Virtual APs in tunnel mode.

 

 

Allowed band

The band(s) on which to use the virtual AP:

 

• a—802.11a band only (5 GHz).

 

• g—802.11b/g band only (2.4 GHz).

 

• all—both 802.11a and 802.11b/g bands (5 GHz and 2.4 GHz). This is the default setting.
