Cisco Cisco IOS Software Release 12.0 S 릴리즈 노트

Caveats describe unexpected behavior in Cisco IOS software releases. Severity1 caveats are the most 
serious caveats; severity 2 caveats are less serious. Severity 3 caveats are moderate caveats, and only 
select severity 3 caveats are included in the caveats document. 

Because Cisco IOS Release 12.0S is based on Cisco IOS Release 12.0, many caveats that apply to 
Cisco IOS Release 12.0 will also apply to Cisco IOS Release 12.0S. For information on severity 1 and 
severity 2 caveats in Cisco IOS Release 12.0, see the 

 document 

located on Cisco.com. 

If you have an account on Cisco.com, you can also use the Bug Toolkit to find select caveats of any 
severity. To reach the Bug Toolkit, log in to 

 and click Technical Support: Tools & 

Resources: Bug Toolkit. (The Bug Toolkit is listed under Troubleshooting.) Another option is to go to

requested cannot be displayed, this may be due to one or more of the following reasons: the defect

marked Cisco Confidential.)

These caveats are documented in the following format:

Symptoms: A description of what is observed when the caveat occurs.

Conditions: The conditions under which the caveat has been known to occur. 

Workaround: Solutions, if available, to counteract the caveat.
