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.
