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.
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.
