Syslog Error When the Table is Full
In the Dell EMC Networking OS, the table full condition is displayed as CAM full only for LPM. But now the LPM is split into two tables.
There are two syslog errors that are displayed:
1 /65 to /128 Table full.
2 0/0 – 0/64 Table full.
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.
Syslog Warning Upon 90 Percent Utilization of CAM
CAM utilization includes both the L3_DEFIP and L3_DEFIP_PAIR_128 table entries to calculate the utilization.
Syslog Warning for Discrepancies Between Congured
Extended Prexes
An error message is displayed if the number of extended prex entries is dierent from the congured value during bootup.
Unied Forwarding Table (UFT) Modes
Unied Forwarding Table (UFT) consolidates the resources of several search tables (Layer 2, Layer 3 Hosts, and Layer 3 Route [Longest
Prex Match — LPM]) into a single exible resource. Dell EMC Networking OS supports several UFT modes to extract the forwarding
tables, as required. By default, Dell EMC Networking OS initializes the table sizes to UFT mode 2 prole, 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 14. UFT Modes — Table Size
UFT Mode L2 MAC Table Size L3 Host Table Size L3 LPM Table Size
Default 72K 72K 16K
Scaled-l3-hosts 8K 136K 16K
Scaled-l3-routes 8K 8K 128K
Scaled-l2–switch 136K 8K 16K
Conguring UFT Modes
To congure the Unied 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.
