searching throughout the stack, in order to perform security, QoS, and other types of
applications. In contrast with binary CAM, TCAM allows a third matching state of "X"
or "Don't Care" bits in data searches ( the first two bit types are "0" and "1"), adding
more flexibility to searches. However, the need to encode three possible states
instead of two also adds greater resource costs.
The maximum number of rules that may be allocated by all applications on the
device is 1024.
The following table lists all applications that can allocate TCAM rules. Each
allocation has its specific allocation policy.
Note:
Some applications allocate rules upon their initiation. Additionally, applications that
initialize during system boot use some of their rules during the startup process.
