Usage
Information
This command applies to both IPv4 and IPv6 CAM Profiles, but is best used when verifying QoS
optimization for IPv6 ACLs.
QoS Optimization for IPv6 ACLs does not impact the CAM usage for applying a policy on a single (or
the first of several) interfaces. It is most useful when a policy is applied across multiple interfaces; it can
reduce the impact to CAM usage across subsequent interfaces.
The following describes the test cam-usage command shown in the following example.
Term Explanation
Stack-Unit
Lists the stack unit or units that are checked. Entering all shows the status for all
stacks.
Portpipe Lists the portpipe (port-set) or port pipes (port-sets) that are checked. Entering
all shows the status for stack-units and port-pipes in the chassis. The port set
value is from 0 to 0.
CAM Partition Shows the CAM profile of the CAM.
Available CAM Identifies the amount of CAM space remaining for that profile.
Estimated CAM
per Port
Estimates the amount of CAM space the listed policy will require.
Status Indicates whether or not the policy will be allowed in the CAM.

Unified Forwarding Table Modes
Unified Forwarding Table (UFT) consolidates the resources of several search tables (Layer 2, Layer 3 Hosts, and Layer 3
Route [Longest Prefix Match — LPM]) into a single flexible resource. The system supports several UFT modes to extract
the forwarding tables, as required. By default, Dell EMC Networking OS initializes the table sizes to UFT mode 2 profile, as it
