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).
Table 10. UFT Modes —Table Size
UFT Mode L2 MAC Table Size L3 Host Table Size L3 LPM Table Size
Default 160K 144K 16K
Scaled-l3-hosts 96K 208K 16K
Scaled-l3-routes 32K 16K 128K
NOTE: 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.
1 Select a mode to initialize the maximum scalability size for L2 MAC table or L3 Host table or L3 Route
table.
