Term Explanation
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.
Example
DellEMC# test cam-usage service-policy input In stack-unit all

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
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).
● Apply the UFT mode configuration to the entire system when you use the CONFIGURATION mode commands. Save the
running-configuration to affect the change.
● Save the changes and reboot the system for UFT mode profiling to take effect.
