Return to the Default CAM Configuration
Return to the default CAM Profile, microcode, IPv4Flow, or Layer 2 ACL configuration using the
keyword
default from EXEC Privilege mode or from CONFIGURATION mode, as shown in Figure 10-3.

CAM Optimization
CAM optimization is supported on platforms s z
When this command is enabled, 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 1 FP entry will be used). When the command is disabled, the system
behaves as described in this chapter.
Troubleshoot CAM Profiling
CAM Profile Mismatches
The CAM profile on all stack-unit must match the system profile. In most cases, the system corrects
mismatches by copying the correct profile to the stack-unit, and rebooting the stack-unit.
QoS CAM Region Limitation
The default CAM profile allocates a partition within the IPv4Flow region to store QoS service policies. If
the QoS CAM space is exceeded, messages similar to the ones in Message 1 are displayed.
If you exceed the QoS CAM space,
allocate more entries in the IPv4Flow region to QoS.
