Syslog Warning for Discrepancies Between Congured
Extended Prexes
An error message is displayed if the number of extended prex entries is dierent from the congured value during bootup.
Unied Forwarding Table (UFT) Modes
Unied Forwarding Table (UFT) consolidates the resources of several search tables (Layer 2, Layer 3 Hosts, and Layer 3 Route [Longest
Prex Match — LPM]) into a single exible resource. Dell Networking OS supports several UFT modes to extract the forwarding tables, as
required. By default, Dell Networking OS initializes the table sizes to UFT mode 2 prole, 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 12. UFT Modes — Table Size

Scaled-l3-routes 32K 16K 128K
Conguring UFT Modes
To congure the Unied 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.
