7 UFT modes Unified Forwarding Table (UFT) gives the flexibility to configure the sizes of internal L2/L3 forwarding tables of a switch to match the needs of particular network environment. A switch in a Layer 2 network may require a larger MAC address table size, while a switch in a Layer 3 network may require a larger routing table size. OS10 supports several UFT modes for the forwarding tables. By default, OS10 selects a UFT mode which provides a reasonable size for all tables. The supported UFT modes are: default, scaled-l2-switch, scaled-l3-hosts, and scaled-l3-routes. Table 4.
