View CAM Usage
View the amount of CAM space available, used, and remaining in each ACL partition using the show cam-
usage command from EXEC Privilege mode.
Example of the show cam-usage Command

QoS CAM Region Limitation
To 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 L3
Cam(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 1
If you exceed the QoS CAM space, follow these steps.
1 Verify that you have configured a CAM profile that allocates 24 K entries to the IPv4 system flow region.
2 Allocate more entries in the IPv4Flow region to QoS.
Dell Networking OS supports the ability to view the actual CAM usage before applying a service-policy. The
test cam-usage service-policy command provides this test framework. For more information, refer to
Pre-Calculating Available QoS CAM Space.
