Release Notes for Cisco IOS Release 12.0 S

Caveats

Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most

serious caveats; severity 2 caveats are less serious.

This section contains only open caveats for the current Cisco IOS 12.0 S maintenance release.

Because Cisco IOS Release 12.0 S is based on Cisco IOS Release 12.0, many caveats that apply to

Cisco IOS Release 12.0 will apply to Cisco IOS Release 12.0 S. For information on severity 1 and 2

caveats in Cisco IOS Release 12.0, see Caveats for Cisco IOS Release 12.0 located on CCO and the

Documentation CD-ROM.

Note If you have an account with CCO, you can use Bug Navigator II to find caveats of

any severity for any release. You can reach Bug Navigator II on CCO at Service

& Support: Online Technical Support: Software Bug Toolkit, or at

http://www.cisco.com/support/bugtools.

Open Caveats—Cisco IOS Release 12.0(14)S

This section describes possibly unexpected behavior by Cisco IOS Release 12.0(14)S. This section

describes only severity 1 and 2 caveats.

Basic System Services

• CSCdm71776

If the slave auto-sync config global configuration command is enabled on a High System

Availability (HSA) system and you enter the config-register global configuration command

followed by the write memory command, the master system configuration register will be set to

change on the next reboot, but the slave configuration register will not be set to change.

Workaround: Enter the slave sync config privileged EXEC command, which will update the slave

configuration register for the next reboot.

• CSCdp19943

The online insertion and removal (OIR) of a slave Route Switch Processor (RSP) might cause the

master to exhibit RSP-3-BAD BUFHDR messages. There is no workaround.
