View CAM Usage
View the amount of CAM space available, used, and remaining in each partition (including IPv4 and IPv6 Flow and Layer 2 ACL sub-
partitions) using the show cam-usage command in EXEC Privilege mode
The following output shows CAM blocks usage for Layer 2 and Layer 3 ACLs and other processes that use CAM space:
Starting from OS 9.11(2.0), ACL filters are optimized to support more than 200 egress ACL rules on the S6000, S6000–ON, S6100–ON,
and Z9100–ON.

Configuring CAM Threshold and Silence Period
This section describes how to configure CAM threshold and silence period between CAM threshold syslog warnings.
The CAM threshold and silence period configuration 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 fixed 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
configured CAM threshold. The configured CAM threshold is a value specific to FP based on CAM features such as Ingress and Egress L2,
