CAM Optimization
To optimize CAM utilization for QoS entries by minimizing the required policy-map CAM space, use the cam-
optimization command.
If you apply a policy map containing classification rules (ACL and/or DSCP/IP-precedence rules) 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).
To disable CAM optimization, use the no cam-optimization command. CAM allocation then behaves as
described in CAM Allocation.
Troubleshoot CAM Profiling
The following section describes CAM profiling troubleshooting.
CAM Profile Mismatches
The CAM profile on all cards must match the system profile. In most cases, the system corrects mismatches
by copying the correct profile to the card, and rebooting the card. If three resets do not bring up the card, or
if the system is running an Dell Networking OS version prior to version 6.3.1.1, the system displays an error
message. In this case, manually adjust the CAM configuration on the card to match the system configuration.
To prevent mismatches, Dell Networking recommends the following:
• Use the eg-default CAM profile in a chassis that has only EG Series line cards. If this profile is used in a
chassis with non-EG line cards, the non-EG line cards enter a problem state.
• Before moving a card to a new chassis, change the CAM profile on a card to match the new system
profile.
• After installing a secondary RPM into a chassis, copy the running-configuration to the startup-
configuration.
• Change to the default profile if downgrading to a Dell Networking OS version earlier than 6.3.1.1.
• Use the CONFIGURATION mode commands so that the profile is change throughout the system.
• Use the EXEC Privilege mode commands to match the profile of a component to the profile of the
target system.
