CLI Guide
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. .
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. Trident 2 supports
several UFT modes to extract the forwarding tables, as required. By default, Dell Networking OS initializes
the table sizes to UFT mode 2 profile, since it provides a reasonable shared memory for all the tables. The
other supported UFT modes are scaled-l3–hosts (UFT mode 3) and scaled-l3–routes (UFT mode 4).
Important Points to Remember
• All line cards/Stack Members within a single system must have the same UFT mode profiles. this
profile must match the system UFT mode profile (the profile on the primary route processor module
[RPM]/ Master Unit of the Stack).
• The UFT mode configuration is applied to the entire system when you use the CONFIGURATION
mode commands. Save the running-configuration to affect the change.
• You MUST save your changes and reboot the system for UFT mode profiling to take effect.
