Problem Description

When a Wireless Control System (WCS) version 4.0, Wireless LAN (WLAN) template is applied to controllers running version 4.0 and Wi-Fi Protected Access WPA or WPA2 is selected as the Layer2 security policy, the Wireless LAN provisioned using this template is programmed without any 802.1x security policy. This problem does not affect individual WLAN configurations using WCS version 4.0.

Background

WLAN template Layer2 security policy options Wi-Fi Protected Access WPA or WPA2 were introduced for controllers with version 3.x. For controllers with version 4.0, customers are advised to use WPA1 or WPA2 Layer2 security policy in the WLAN template. Version 3.x Layer2 security policy options were carried over into version 4.0 software release to maintain backward compatibility between WLC version 3.x and WLC version 4.0 releases.

See the Cisco Wireless Control System Configuration Guide for more information.

Problem Symptoms

When a Wireless Control System (WCS) version 4.0 WLAN template is applied to controllers running version 4.0 and WPA or WPA2 is selected as the Layer2 security policy, the WLAN provisioned using this template is programmed without any 802.1x security policy.

Workaround/Solution

  1. Only apply a WPA1 or WPA2 WLAN template Layer2 security policy to controllers running version 4.0 software.

  2. Use a WPA or WPA2 WLAN template Layer2 security policy to Controllers running version 3.x software.
