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:
● Re-configure the CAM threshold
● Add or delete an ACL rule
Example of Syslog message on CAM usage
Following table shows few possible scenarios during which the syslog message appear on re-configuring the CAM usage
threshold value.
Consider if the last CAM threshold was set to 90 percent and now you re-configure the CAM threshold to 80. And, if the
current CAM usage is 85 percent, then the system displays the syslog message saying that the CAM usage is above the
configured CAM threshold value.

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 CONFIGURATION mode, as shown in the following example.
Example of the cam-profile default Command
Dell(conf)#cam-profile ?
default Enable default CAM profile
eg-default Enable eg-default CAM profile
ipv4-320k Enable 320K CAM profile
ipv4-egacl-16k Enable CAM profile with 16K IPv4 egress ACL
ipv6-extacl Enable CAM profile with extended ACL
l2-ipv4-inacl Enable CAM profile with 32K L2 and 28K IPv4 ingress ACL
unified-default Enable default unified CAM profile
Dell(conf)#cam-profile default microcode ?
default Enable default microcode
lag-hash-align Enable microcode with LAG hash align
