Checking DDTs Database and Release Notes for Workarounds
This section describes different methods you can use to check for IOS software bugs (defect tracking
tool numbers [DDTs]) in your version of IOS software. Often, your problems with the switch router have
been fixed or a workaround has been determined in a more recent version of software.
There are two ways to check for known bugs in the IOS software:
• Using Bug Toolkit, page 3-5
• Checking IOS Release Notes, page 3-7
Using Bug Toolkit
Bug Toolkit allows you to search for known bugs based on, a known bug ID, software version, feature
set, product name, and keywords.
To search the DDT database, you can access Bug Toolkit on the World Wide Web at
http://www.cisco.com/cgi-bin/Support/Bugtool/launch_bugtool.pl
.
If you are not already logged in to Cisco.com, enter your user name and password at the login prompt.
You can search for known ATM switch router software bugs using either of the following:
• Searching for Bugs Using the Bug ID, page 3-6 (for example, “CSCdr99175”)
• Searching for Bugs Using the Software and Hardware Product Name, page 3-6 (for example,
“Catalyst 8540 Switches”)
The process is different depending on the search information you use.
