Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S
• CSCin57433
Symptoms: All of the configured data-link connection identifiers (DLCIs) on a Multilink Frame
Relay (MFR) interface are not active.
Conditions: This symptom is observed if a Cisco router is booted with MFR in the startup
configuration.
Workaround: There is no workaround.
• CSCin57765
Symptoms: A router may become unresponsive and may reload when you append a file whose size
is not a multiple of 512 bytes to an Advanced Technology Attachment (ATA) Flash card (for
example, bootdisk, disk0, disk1).
For example, this situation may occur when you enter the show command | tee /append url
privileged EXEC command.
Conditions: This symptom is observed on a Cisco platform that runs a Cisco IOS image that contains
the fix for caveat CSCdz27200 and that utilizes an ATA Flash card. A list of the affected releases
can be found at http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCdz27200.
Cisco IOS software releases that are not listed in the “First Fixed-in Version” field at this location
are not affected.
Workaround: Write the output of the show command to a new file instead of appending it to an
existing file by entering the show command | tee url privileged EXEC command.
• CSCuk39887
Symptoms: Traffic that passes through a tunnel interface may be dropped because the application
inspection (also referred to as “fixup”) is disabled on the tunnel interface adjacency.
Conditions: This symptom is observed in Cisco IOS Release 12.0(24)S or a later release.
Workaround: Toggle Cisco Express Forwarding (CEF) by entering the no ip cef distributed global
configuration command followed by the ip cef distributed global configuration command.
• CSCuk43457
Symptoms: The output of the show route-map EXEC command may indicate that duplicate traffic
indices have been configured.
Conditions: This symptom is observed on a Cisco 7500 series that is configured for Border Gateway
Protocol (BGP) policy accounting. The symptom may also occur on other platforms.
Workaround: There is no workaround.
• CSCuk44928
Symptoms: When you save a configuration first to the standby Performance Routing Engine (PRE)
and then to the active PRE, the configuration may not be saved and the following error message may
be generated:
startup-config file open failed (Device or resource busy)
Conditions: This symptom is observed on a Cisco 10000 series that is configured with redundant
PREs and that runs Cisco IOS Release 12.0(26)S. The symptom may also occur in other Cisco IOS
releases.
Workaround: There is no workaround.
• CSCuk46911
Symptoms: When you enter the exec slot 0 clear log EXEC command on a Cisco 12000 series
router, the line card may stall.
