HWACLMAN Messages
HWACLMAN Messages
This section contains the hardware ACL Manager (HWACLMAN) messages.
Error Message C4K_HWACLMAN-4-ACLHWPROGERR:[input/output] [char] - hardware TCAM
limit, [char]
Explanation
Some ACL-based features cannot be fully programmed into the hardware. Packets that
use these features complete processing in the software. If the feature is a policy map, then QoS is
completely disabled (on the specific interface).
This message lists the impacted feature; further messages list the specific failure that occurred.
Recommended Action This is an informational message only. No action is required.
Error Message C4K_HWACLMAN-4-ACLHWPROGERRREASON:[input/output] [object-info]
[char] - [char]
Explanation
This message provides a specific failure that prevented ACL-based features from being
fully programmed into the hardware.
Recommended Action This is an informational message only. No action is required.
Error Message C4K_HWACLMAN-4-CAMAUDIT: ACl/QOS CAM Health Check: [input/output]
[char] Index: [dec] [char] ( Cumulative Error Count: [dec] )
Explanation
The background system health monitor detected a potential problem.
Recommended Action If this is a software error, the system has already corrected itself automatically
and no action is required. If this is a hardware error, power cycle the switch.
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.
