Term Explanation
Linecard Lists the line cards that are checked. Entering all displays the status for line cards in
the chassis.
Portpipe Lists the port pipes (port sets) that are checked. Entering all displays the status for all
line cards 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.
