Codes: * - cam usage is above 90%.

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.

The following section describes CAM profiling troubleshooting.

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:

| OUT-L3 ACL

| OUT-V6 ACL

| OUT-L2 ACL
