CAM Optimization
When you enable the CAM optimization, if a Policy Map containing classification rules (ACL and/or DSCP/ ip-precedence rules)
is applied to more than one physical interface on the same port-pipe, only a single copy of the policy is written (only one FP
entry is used). When you disable this command, the system behaves as described in this chapter.
Troubleshoot CAM Profiling
The following section describes CAM profiling troubleshooting.
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 1/20/1) 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

Syslog Error When the Table is Full
In the Dell Networking OS, the table full condition is displayed as CAM full only for LPM. But now the LPM is split into two
tables. There are two syslog errors that are displayed:
1. /65 to /128 Table full.
2. 0/0 – 0/64 Table full.
A table-full error message is displayed once the number of entries is crossed the table size. Table-full message is generated
only once when it crosses the threshold. For subsequent addition of entries, the table-full message is not recorded you clear
the table-full message. The table-full message is cleared internally when the number of entries is less than the table size.
