The following Cisco Aironet Series APs are supported in the Cisco Mobility Express network:

Note	APs listed under primary APs can also function as subordinate APs. The software on the APs listed under primary APs can be converted from Cisco Mobility Express to CAPWAP Lightweight AP software and vice versa. For ordering information, visit the Cisco Aironet Access Points Ordering Guide

Depending on the primary AP in the Cisco Mobility Express network, the maximum number of APs and clients supported varies.

Note	If there are more than 25 Access Points in a Mobility Express network, the primary AP(running the Wireless LAN controller function) can service a maximum of 20 clients. This limit only applies to primary AP and not any other Access Point in the Mobility Express network.

  • Cisco Aironet 1540 Series

  • Cisco Aironet 1815m

• Support for Communications Assistance for Law Enforcement Act (CALEA)

• Support for centralized NAT configuration

The following table lists the Cisco Wireless Release software for Cisco Aironet APs that are Cisco Mobility Express capable (primary APs).

Note

Choose the appropriate AP software based on the following: Cisco Mobility Express software to be used for converting the AP from the unified wireless network CAPWAP lightweight AP to a Cisco Mobility Express-capable AP (primary AP) AP software image bundle to be used either for upgrading the Cisco Mobility Express software on the primary AP or for updating the software on the subordinate APs or both

Known Limitations

• Internet Group Management Protocol (IGMP)v3 is not supported on Cisco Aironet Wave 2 APs.

• If the Cisco AP has a Cisco Mobility Express software image, it will not support link aggregation groups (LAG) even if it is 802.3ad (LACP)-compliant.

• Over-the-DS fast BSS transition and fast transition PSK authentication are not supported.

Caveats

Caveats describe unexpected behavior in the Cisco Mobility Express network solution. Severity 1 caveats are the most serious while Severity 2 caveats are less serious. Severity 3 caveats are moderately serious and only select severity 3 caveats are listed here.

The and sections list the caveats in the Cisco Mobility Express network solution for Cisco Wireless Release . The following information is provided for each caveat:

• Identifier—Each caveat is assigned a unique identifier (ID) with a pattern of CSCxxNNNNN, where x is any letter (a-z) and N is any number (0-9). These IDs are frequently referenced in Cisco documentation, such as Security Advisories, Field Notices and other Cisco support documents. Technical Assistance Center (TAC) engineers or other Cisco staff can also provide you with the ID for a specific caveat.

• Description—A description of what is observed when the caveat occurs.
