Caveats for Release 12.2(2)XQ1

September 4, 2001

Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most serious caveats, severity 2 caveats are less serious, and severity 3 caveats are the least serious of these three severity levels.

Caveats in Cisco IOS Releases 12.2 and 12.2 T are also in Cisco IOS "special" releases (such as 12.2(2)XQ1). For information on caveats in Cisco IOS Release 12.2, see Caveats for Cisco IOS  Release 12.2. For information on caveats in Cisco IOS Release 12.2 T, see Caveats for Cisco IOS  Release 12.2 T. These two documents list severity 1 and 2 caveats and are located on CCO and the Documentation CD-ROM.

Note If you have an account with, you can use Bug Navigator II to find caveats of any severity for any release. To reach Bug Navigator II, Login to and click Software Center: Cisco IOS Software: Cisco Bugtool Navigator II. Another option is to go directly to
