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.
Setting CAM Threshold and Silence Period
To congure the CAM threshold and silence period, use the following commands.
• Assign the CAM threshold percentage
CONFIGURATION mode
cam-threshold threshold {default | threshold-percent}
The range of threshold value is from 1 to 100. The default threshold value is 90 percent.
• Assign the silence period for syslog warning.
CONFIGURATION mode
cam-threshold threshold {default | threshold-percent} silence-period {default | silence-
period-value}
The range of silence period is from 0 to 65535. The default is 0 seconds.
NOTE
:
If you delete a FP in a CAM region that is assigned with threshold, a syslog warning appears even during the silence period.
The system triggers syslog during the following events:
