Content Addressable Memory | 277
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 13-5, "IPv4Flow CAM
Sub-partition Sizes," in Content Addressable Memory..
• 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 IPv4Flow by the selected CAM profile (refer to Table 13-1, "CAM Profile Descriptions," in
Content Addressable Memory.); 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:
FTOS(conf)#cam-ipv4flow default
FTOS#copy running-config startup-config
File with same name already exist.
Proceed to copy the file [confirm yes/no]: yes
