Setup Guide

The IPv4 QoS region reserves 32 ACLs. Sharing is calculated on the remaining ACLs. For example, if you
configure the IPv6 ACL value as 2, the system reserves 32 entries for IPv4 QoS and the remaining 224
entries (256-32) are shared between IPv4 QoS and IPv6 ACL entries according to the configured CAM
sharing percentages.
The sum of the percentage values between the two regions must be 100.
Example
The following example shows that IPv4 QoS is disabled and IPv6 ACL is set to 4. With this configuration,
you can share a total of 480 entries between the IPv4 QoS and IPv6 ACL regions after allocating 32
entries for IPv4 QoS.
DellEMC(conf)# cam-sharing ipv4qos 50 ipv6acl 50
DellEMC(conf)#cam-acl l2acl 0 ipv4acl 0 ipv6acl 4 ipv4qos 0 l2qos 0 l2pt

cam-threshold
Configure CAM threshold value for sending the syslog message on CAM usage. Configure silence period for stop receiving
syslog message on CAM usage.
Syntax
cam-threshold threshold {default | threshold-percent} silence-period
{default | silence-period-value}
Defaults
Enabled
Parameters
threshold default
Enter the keyword default for CAM usage threshold for notification of the CAM
usage through syslog message. The default threshold value is 90 percent.
threshold
threshold-
percent
Enter the threshold percent for notification of the CAM usage through syslog
message. The range is from 1 to 100 percent.
silence-period
default
Enter the keyword default to set the silence period for receiving syslog message
regarding CAM usage for CAM region, slot/portpipe. The default silence period is 0
seconds.
silence-period
silence-period-
value
Enter the silence period for stop receiving syslog message for the respective CAM
region, slot/portpipe. The range is from 0 to 65535 seconds.

Usage
Information
The no cam-threshold command will set the CAM threshold to 90 percent and silence period to 0.
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 not configurable and the values are fixed to 90 percent and 0 respectively.
Example
DellEMC(conf)#cam-threshold threshold 2 silence-period 2
DellEMC(conf)#do show running-config | g cam-threshold
cam-threshold threshold 2 silence-period 2
