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.
Explanation
Lists the line cards that are checked. Entering all displays the status for line
cards in the chassis.
Lists the port pipes (port sets) that are checked. Entering all displays the
status for all line cards and port pipes in the chassis.
Shows the CAM profile of the CAM.
Identifies the amount of CAM space remaining for that profile.
Estimates the amount of CAM space the listed policy will require.
Indicates whether or not the policy will be allowed in the CAM.
