When youdisable this command, the system behaves as described in this chapter.Troubleshoot CAM ProfilingThe following section describes CAM profiling troubleshooting.QoS CAM Region LimitationTo store QoS service policies, the default CAM profile allocates a partition within the IPv4Flow region.If the QoS CAM space is exceeded, a message similar to the following displays.%EX2YD:12 %DIFFSERV-2-DSA_QOS_CAM_INSTALL_FAILED: Not enough space in L3Cam(PolicyQos) for class 2 (Te 1/20) entries on portpipe 1 for linecard 1%EX2YD:12 %DIFFSERV-2-DSA_QOS_CAM_INSTALL_FAILED: Not enough space in L3 Cam(PolicyQos) for class 5 (Te 1/22) entries on portpipe 1 for linecard 1Content Addressable Memory (CAM) 239
