Resolved Caveats—Cisco IOS Release 12.0(27)S3
• CSCed82592
Symptoms: A PXF engine on a Cisco 10000 series may unexpectedly crash and then the router may
crash.
Conditions: This symptom is observed on a Cisco 10000 series that runs Cisco IOS
Release 12.0(23)S5.
Workaround: There is no workaround.
• CSCed92837
Symptoms: After a Stateful Switchover (SSO) occurs on a Cisco 7500 series, the standby Route
Switch Processor (RSP) my hang just before downloading the image. This situation may prevent the
router from entering the STANDBY-HOT state and from being capable to perform a switchover until
the standby RSP is reset.
Conditions: This symptom is observed on Cisco 7500 series that runs Cisco IOS Release 12.0 S or
12.2 S and that is configured for SSO/Nonstop Forwarding (NSF).
Workaround: There is no workaround. After the problem occurs, you can recover the router by either
waiting for an IPC timer to expire (the default time is 30 minutes) or by entering the hw-module
sec-cpu reset command.
• CSCed95753
Symptoms: A GRE tunnel may not work on a PE router.
Conditions: This symptom is observed on a Cisco 12000 series that runs the gsr-p-mz image of
Cisco IOS Release 12.0(25)S or a later release.
Workaround: There is no workaround.
• CSCee06794
Symptoms: DTS may not work properly on dot1q Fast Ethernet subinterfaces. Traffic is not shaped
at the expected rate
Conditions: This problem is observed on a Cisco 7500 series that is configured as a PE router and
that runs Cisco IOS Release 12.2(12i). The symptom may also occur in other releases.
Workaround: If this is an option, use ISL subinterfaces.
• CSCee12235
Symptoms: A Cisco platform reloads because of a watchdog timer expiration.
Conditions: This symptom is observed on a Cisco platform that runs Cisco IOS Release 12.2(20)S2
or Release 12.3 under the following conditions:
- A service policy (“A”) is attached to an ATM PVC.
- Policy-map “A” is renamed to “B”.
