What's New in Cisco Wireless Release 8.8.263.0

This release is to address the caveats listed in the Resolved Caveats and Open Caveats sections.

Caveats

Caveats describe unexpected behavior in the Cisco Wireless Network Sensor software. Severity 1 caveats are the most serious while Severity 2 caveats are less serious.

The Resolved Caveats and Open Caveats sections list the caveats in the Cisco Wireless Release 8.8.263.0. 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 access to the Cisco bug tracking system, which maintains information about bugs and vulnerabilities in the Cisco Wireless Network Sensor software 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.
