Resolved Caveats—Cisco IOS Release 12.0(27)S2
• CSCed30253
Symptoms: WRED classification may fail.
Conditions: This symptom is observed when you configure WRED and pass traffic.
Workaround: There is no workaround.
• CSCed32758
Symptoms: A reload or online insertion and removal (OIR) of any line card on a Cisco 12000 series
Internet router chassis with a 1+1 Automatic Protection Switching (APS) configuration between two
CHOC-48 line cards may cause a “deadman timer expired” error. This may result in an incorrect
switch working once the line card comes up.
Conditions: This symptom is observed on a Cisco router with a channelized OC48 line card that is
running the c12kprp-p-mz image of Cisco IOS Release 12.0(24)S4.
Workaround: There is no workaround.
• CSCed37615
Symptoms: A router may reload unexpectedly after renaming a policy-map the second time.
Conditions: This defect may be observed if there are at least two policies configured.
Workaround: Avoid renaming the policy-map.
• CSCed41067
Symptoms: When the cache is lost, a router correctly detects that the cache is no longer available,
but HTTP requests are still forwarded to the cache.
Conditions: This symptom is observed on a Cisco 7500 series with dCEF enabled.
Workaround: Disable dCEF.
• CSCed44319
Symptoms: A file that is copied to an ATA disk may become corrupted.
Conditions: This symptom is observed on any Cisco IOS image that contains the fix for
CSCdz27200. The problem does not occur on a disk that is formatted with 16 or less sectors/cluster.
Workaround: Use an ATA disk that is formatted with 16 or less sectors/cluster. The show disk all
command indicates how many sectors are configured per cluster.
• CSCed45460
Symptoms: The hw-module slot slot-number ip multicast hw-accelerate source-table size 4096
offset 0 command is not synced to a standby RP if a line card is reloaded while the standby RP is
booting.
Conditions: Symptom is observed on a Cisco 12000 series that runs Cisco IOS Release 12.0(28)S.
Workaround: Wait until the standby RP is fully operational before entering the above-mentioned
command.
• CSCed45746
Symptoms: Several prefixes for non-redistributed connected interfaces in different VRFs may be
partially bound to the same MPLS-VPN label, thus disrupting traffic bound to one or more of these
VRFs.
Conditions: This symptom can occur on a Cisco router that runs Cisco IOS Releases 12.2, 12.2T,
12.0S, 12.3 after the VRF interfaces have flapped. The symptom may occur in all code levels of
these releases.
Workaround: Clear the routes in the VRFs in sequence.
