Checking IOS Release Notes
Release notes describe the features and caveats for Cisco IOS software releases. The release notes are
listed by both product and IOS release number.
Note All information pertains to both the Catalyst 8540 CSR and Catalyst 8510 CSR platforms, unless
differences between the platforms are noted in the text.
The “Caveats” section of the release note lists known caveats for the switch router by tracking the
DDTS number and the release number, and indicates whether the caveat has been corrected.
The “Caveat Symptoms and Workarounds” section summarizes caveat symptoms and suggested
workarounds for the switch routers. You can also search thorough this section online, using either a word
string or the DDTS number.
Troubleshooting Hardware and Software Version Problems
A common error you may encounter is the incompatibility of hardware modules and the IOS software
version needed to perform a particular function. Check the Hardware and Software Compatibility Matrix
document, available online, to confirm that you are using IOS software that supports the various
hardware components installed in your switch router.
