It is Cisco policy to document all bugs that can be encountered in released product. The Bug Search Tool (BST) is used to find such bugs. See the Bug Search Tool Help & FAQ page for general assistance in using this tool.
One limitation of BST is that the bugs that apply to a given product cannot always be found when searching for that particular product. For example, when searching for bugs that apply to the Cisco 5520 Wireless Controller, no bugs are found. This article explains how to find bugs that apply to different Cisco Wireless LAN Controller (WLC) and Access Point (AP) products.
Note: When entering version numbers, do not use the "dotted quad" style notation (for example 220.127.116.11), as BST does not understand that format; instead, use the w.x(y.z) notation, for example, 8.0(120.0).
AireOS Wireless LAN Controller Bugs
For all Wireless LAN Controllers that run AireOS, applicable bugs will be found in BST by searching on: Product: Series/Model = Cisco 5508 Wireless Controller
This applies to the 2500 Series, 5500 series, 8500 Series, Flex 7500 Series, WiSM2, and Virtual Wireless LAN Controller (as well as to older AireOS WLCs.)
