View CAM Usage
View the amount of CAM space available, used, and remaining in each partition (including IPv4Flow and Layer 2 ACL sub-partitions) using
the show cam-usage command from EXEC Privilege mode.
Example of the show cam-usage Command

Conguring CAM Threshold and Silence Period
This section describes how to congure CAM threshold and silence period between CAM threshold syslog warnings.
The CAM threshold and silence period conguration is applicable only for Ingress L2, IPv4, IPv6 and Egress L2, IPv4, and IPv6 ACL CAM
groups. For other ACL CAM regions, the CAM threshold and silence period is xed and the values are 90 percent and 0 respectively.
You can assign CAM threshold value using cam-threshold command to receive syslog messages when the CAM usage reaches the
congured CAM threshold. The congured CAM threshold is a value specic to FP based on CAM features such as Ingress and Egress L2,
IPV4, IPV6. The system checks the CAM usage of the features with the set threshold to display a syslog message, which contains the
CAM region, slot/port-pipe and pipeline information. By default, syslog warning appears when the CAM usage is 90 percent.
You can also congure the silence period for the syslog message on the CAM usage. A syslog warning appears when the CAM usage
exceeds the congured CAM threshold. The silence period starts after the initial syslog warning. The syslog warning does not appear until
the silence period is active. By default, the silence period is 0 seconds.
