Content Addressable Memory (CAM) | 285
The IPv4Flow CAM partitions have sub-partitions for several types of information. Table 11-5 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 11-5.
• The IPv4Flow configuration is applied to entire system when you enter the command
cam-ipv4flow
from CONFIGURATION mode, however, you must save the running-configuration to affect the
change.
The amount of space that is allocated among the sub-partitions must be equal to the amount of CAM space
allocated to IPv4Flowby the selected CAM profile (refer to Table 11-1.); Message 3 is displayed if the
total allocated space is not correct.
The minimum amount of space that can be allocated to any sub-partition is 1K, except for System flow, for
which the minimum is 4K.
To re-allocate CAM space within the IPv4Flow partition on the entire system:
