Ifthe QoS CAM space is exceeded, messages similar to the ones in Message 5 are displayed.If you exceed the QoS CAM space:FTOS version 7.4.1 introduced the ability to view the actual CAM usage before applying a service-policy.The command test cam-usage service-policy provides this test framework, see Pre-calculating AvailableQoS CAM Space on page 874.Message 5 QoS CAM Region Exceeded%EX2YD:12 %DIFFSERV-2-DSA_QOS_CAM_INSTALL_FAILED: Not enough space in L3 Cam(PolicyQos) forclass 2 (Gi 12/20) entries on portpipe 1 for linecard 12%EX2YD:12 %DIFFSERV-2-DSA_QOS_CAM_INSTALL_FAILED: Not enough space in L3 Cam(PolicyQos) for class 5 (Gi 12/22)entries on portpipe 1 for linecard 12Step Task1 Verify that you have configured a CAM profile that allocates 24K entries to the IPv4 system flow region. SeeView CAM Profiles on page 291.2 Allocate more entries in the IPv4Flow region to QoS. See Configure IPv4Flow Sub-partitions on page 293.Note: For troubleshooting other CAM issues see the E-Series Network Operations Guide.
