Autonomous AP as WGB (Multiple VLAN)

In this post we will learn how to configure an autonomous AP as WGB with Multiple VLAN.

How to setup Root AP and WGB: Check this post

***I don’t have extra switch so I will force WGB to connect to clicnet in vlan 12.

***In my post WGB and Root AP both are on vlan 11(Native) and Client will get the IP in vlan 12.

*** Link between RootAP and switch is trunk.

Switch Config:

 Int fa0/24
 Switchport trunk encapsulation dot1q
 Switchport trunk native vlan 11
 Switchport trunk allowed vlan 11,12
 Switchport mode trunk

 WGB_2vlan

Remembering Points:

  1. The AP to which a WGB associates can treat the WGB as an infrastructure device or as a normal client. By default, AP treats WGB as client devices.
  1. If WGB is an infrastructure client, it can associate to an infrastructure SSID. Infrastructure SSIDs are used to authenticate Bridges, Repeaters…Etc. A WGB in by default is a “client”, not an “infrastructure client” and therefore cannot associate to an infrastructure SSID.

Use of Infrastructure-Client Command:

  1. Used for Reliable Multicast
  2. To make WGB as Infrastructure-Client so that WGB can associate to Infrastructure-SSID.

In my example WGB is connected root AP via RSCCIEW WLAN interface.

WGB authentication with LEAP-WPA2.

Normally its not recommended by cisco to use multiple vlan on WGB 🙂
