Cisco Cisco IOS Software Release 12.4(4)T

© 2005–2012 Cisco Systems, Inc. All rights reserved.

This document lists severity 1 and 2 caveats and select severity 3 caveats for Cisco IOS Release 12.4T, 
up to and including Cisco IOS Release 12.4(24)T12. Caveats describe unexpected behavior or defects in 
Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less 
serious.

Because Cisco IOS Release 12.4T is based on Cisco IOS Release 12.4, many caveats that apply to 
Cisco IOS Release 12.4 will also apply to Cisco IOS Release 12.4T. For information on severity 1 and 
severity 2 caveats in Cisco IOS Release 12.4, see the 

 document 

located on Cisco.com.
