CAM Optimization
When you enable the CAM optimization, if a Policy Map containing classication 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).
Troubleshoot CAM Proling
The following section describes CAM proling troubleshooting.
CAM Prole Mismatches
The CAM prole on all cards must match the system prole. In most cases, the system corrects mismatches by copying the correct

version prior to version 6.3.1.1, the system displays an error message. In this case, manually adjust the CAM conguration on the card
to match the system conguration.
To prevent mismatches, Dell Networking recommends the following:
