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).

Scaled-l3-hosts

Scaled-l3-routes

On the C9010, OpenFlow supports only the scaled-l3-hosts hardware forwarding-table mode

(UFT mode 3), providing a unified forwarding table (UFT) of:

L2 MAC entries: 160K

L3 host entries: 144K

L3 route entries: 16K

OpenFlow does not support the scaled-l3-routes forwarding-table mode (UFT mode 4) on the C9010.

Configuring UFT Modes

To configure the Unified Forwarding Table (UFT) modes, follow these steps.

Select a mode to initialize the maximum scalability size for L2 MAC table or L3 Host table or L3 Route
