Overview of Cisco Mobility Express
The Cisco Mobility Express wireless network solution comprises of at least one 802.11ac Wave 2 Cisco Aironet Series access point (AP) with an in-built software-based wireless controller (WLC) managing other APs in the network.
The AP acting as the WLC is referred to as the master AP while the other APs in the Cisco Mobility Express network, which are managed by this master AP, are referred to as subordinate APs.
In addition to acting as a WLC, the master AP also operates as an AP to serve clients along with the subordinate APs.
Cisco Mobility Express provides most features of a Cisco WLC and has the capability to interface with the following:
-
Cisco Prime Infrastructure—For simplified network management, including managing AP groups
-
Cisco Identity Services Engine—For advanced policy enforcement
-
Connected Mobile Experiences (CMX)—For providing presence analytics and guest access using Connect & Engage
For more information about the Cisco Mobility Express solution, including its setup and configuration, see the Cisco Mobility Express User Guide, Release 8.9.

Installing Cisco Mobility Express Software
For software installation instructions, see the “Getting Started” section in the Cisco Mobility Express User Guide for Release 8.9.
Limitations and Caveats
Known Limitations
-
Internet Group Management Protocol (IGMP)v3 is not supported on Cisco Aironet Wave 2 APs.
-
If you have IPv6 flex ACLs configured in the Cisco Mobility Express network, you may face issues downgrading the Cisco Mobility Express software image from Cisco Wireless Release 8.7.102.0 or newer to Cisco Wireless Release 8.6.101.0 or older.
This issue can be resolved by removing all IPv6 ACLs as these are not supported in Cisco Mobility Express, Release 8.6.101.0 or older.
-
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.
-
Starting from Cisco Mobility Express Release 8.8.111.0, when you set the Security Type for a WLAN to Central Web Auth, the required ACLs are no longer auto-generated. You must create the ACLs manually.
-
When downgrading from Cisco Mobility Express AP version 8.8 or 8.9 to version 8.5 with the Cisco Catalyst 3850 switch, the Cisco AP stops responding and fails to come up as a controller. This issue occurs only when downgrading the AP. The AP upgrades without any issues.
-
An AP image master requires a minimum memory of 210 MB to create an image. If the memory is below the image creation threshold, an invalid master status is sent to the controller. To avoid this issue, the joining AP must stream the image if there are no other available masters. Another alternative is to add an external AP of the same type, which would have more memory when compared to the internal AP.
-
In Cisco Mobility Express, the show boot command displays information that is obtained from the AP. Only when the controller is upgraded and rebooted, the show boot command points to the upgraded version. If the controller is upgraded and not rebooted, the show boot command variables are not populated. It will still show the old image as the default image. This is because, unlike AireOS, Cisco Mobility Express updates its data structures from the information obtained from the internal AP.
-
The Cisco Aironet 1852 Access Point does not join Cisco Mobility Express 1562, as the master Cisco Mobility Express1562 does not include the image required for the Cisco Aironet 1852 AP.
-
If you continue to perform an upgrade even after all the APs have successfully completed upgrading, the following message is displayed "Transfer cannot happen because download is already Initiated! Abort before initiating the download again".
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 8.9.100.0 and 8.9.111.0. 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.
Cisco Bug Search Tool
The Cisco Bug Search Tool (BST), which is the online successor to the Bug Toolkit, is designed to improve the effectiveness in network risk management and device troubleshooting. The BST allows partners and customers to search for software bugs based on product, release, and keyword, and aggregates key data, such as bug details, product, and version. The tool has a provision to filter bugs based on credentials to provide external and internal bug views for the search input.
For more information about how to use the Cisco Bug Search Tool effectively, including how to set email alerts for bugs, filter bugs, and save bugs and searches, see the Bug Search Tool Help & FAQ page.
You can access the listed bugs through the BST. This web-based tool provides you with access to the Cisco bug tracking system, which maintains information about bugs and vulnerabilities in the Cisco Mobility Express network solution and other Cisco hardware and software products.
Click the Caveat Identifier number in the table. The corresponding BST page is displayed with details of the bug.
