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.
