What are some of the options that can be configured on a Cisco wireless LAN controller (WLC) to improve its interoperability with non-Cisco devices?
A. The interoperability of a WLC can be improved through these options: • Proprietary features reduce the chance of interoperability between third party devices. These are the proprietary features of Cisco: • Aironet IE – Aironet IE contains information, such as the access point name, load, number of associated clients, and so on sent out by the access point in the beacon and probe responses of the WLAN. CCX clients use this information to choose the best access point with which to associate. • MFP: Management Frame Protection is a feature introduced to protect the management frames, such as de-authentication, disassociation, beacons, and probes wherein the access point adds a Message Integrity Check Information Element (MIC IE) to each of the management frames. Any discrepancy in the MIC IE generates an alert. These features are enabled by default for any WLAN that is created on the WLC. In order to disable these features, click the WLANs menu in the WLC.
