UFT modes

A switch in a Layer 2 (L2) network may require a larger MAC address table size, while a switch in a Layer 3 (L3) network may require a larger routing table size. Unified forwarding table (UFT) offers the flexibility to configure internal L2/L3 forwarding table sizes.

OS10 supports several UFT modes for the forwarding tables. By default, OS10 selects a UFT mode that provides a reasonable size for all tables. The supported UFT modes are: default, scaled-l2–switch, scaled-l3–hosts, and scaled-l3–routes.

NOTE This feature is not supported on the Z9332F-ON platform.
