Error Message C4K_HWACLMAN-4-CAMBLOCKMASKALLOCFAILED: CAM state memory allocation
failure in region [dec]
Explanation
The software could not allocate memory to maintain a software copy of the hardware
classification TCAM masks that are used for ACL and QoS functionality.
Recommended Action This condition should never occur. If you see this message, copy it exactly and
contact your technical support representative.
Error Message C4K_HWACLMAN-4-CLASSIFCAMPARITYERROR: Parity error detected in
[input/output] Classification CAM [char] Cell [object-info] and corrected
Explanation
The system detected and fixed a parity error in the hardware. If you see this error
repeatedly, there is a strong likelihood of a hardware fault and the supervisor engine will need to be
replaced.
Recommended Action The software fixes the parity error by rewriting the CAM entries to the
hardware. If the problem persists, contact your technical support representative.
Error Message C4K_HWACLMAN-4-CLASSIFCAMREPLYPARITYERROR: Parity error detected in
lookup response from [input/output] Classification CAM, Response Contents:
[char]
Explanation
The system detected a transient error in the classification TCAM operation. If you see
this message repeatedly, there is a strong likelihood of a fault in the switching engine ASICs and the
supervisor engine will need to be replaced. Software will attempt to fix the parity error by rewriting
the TCAM entries to the hardware.
Recommended Action If the problem persists, contact your technical support representative.
Error Message C4K_HWACLMAN-4-CLASSIFCAMREQPARITYERROR: Parity error detected in
lookup request to [input/output] Classification CAM, Data [char] Address
[char]
Explanation
The system detected a transient error in the Classification TCAM operation. If you see
this error repeatedly, there is a strong likelihood of a fault in the switching engine ASICs and the
supervisor engine will need to be replaced.
Recommended Action If the problem persists, contact your technical support representative.
Error Message C4K_HWACLMAN-4-FAILEDTOSWITCHPORTTAGS: Failed to switch port tags, old
tag: [object-info] new tag: [object-info] . Software paths: [dec] Hardware
paths: [dec]
Explanation
Software failed to switch tags. This could be transient error. The ACL that we were
trying to program will not become active. (The software and hardware path counts are provided for
use by engineers in troubleshooting.)
Recommended Action Detaching and attaching ACLs (and policies) again may solve the problem.
