Configure IPv4Flow Sub-partitions
IPv4Flow sub-partitions are supported on platform e
The IPv4Flow CAM partition has sub-partitions for several types of information. Table 10-5 lists the types
of
information stored in this partition and the number of entries that FTOS allocates to each type.
You can re-configure the amount of space allocated for each type of entry. FTOS requires that you specify
an amount of CAM space for all types and in the order shown in Table 10-5.
