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-l2switch, scaled-l3hosts, and scaled-l3routes.
NOTE: This feature is not supported on the Z9332F-ON platform.
