A table-full error message is displayed once the number of entries is crossed the table size. Table-full
message is generated only once when it crosses the threshold. For subsequent addition of entries, the table-
full message is not recorded you clear the table-full message. The table-full message is cleared internally
when the number of entries is less than the table size.

Unified Forwarding Table (UFT) Modes
Unified Forwarding Table (UFT) consolidates the resources of several search tables (Layer 2, Layer 3 Hosts,
and Layer 3 Route [Longest Prefix Match — LPM]) into a single flexible 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 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).
