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
R1#show cam-usage

Conguring CAM Threshold and Silence Period
This section describes how to congure CAM threshold and silence period between CAM threshold syslog warnings.
The CAM threshold and silence period conguration 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
congured CAM threshold. The congured CAM threshold is a value specic 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 congure the silence period for the syslog message on the CAM usage. A syslog warning appears when the CAM usage
exceeds the congured 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.
