Viewing TCAM Utilization[
The device architecture uses a TCAM (Ternary Content Addressable Memory) to
support packet actions in wire speed.
TCAM holds the rules produced by applications, such as ACLs (Access Control
Lists), Quality of Service (QoS), IP Routing and user-created rules. The maximum
number of TCAM rules that can be allocated by all applications on the device is
512.
Some applications allocate rules upon their initiation. Additionally, processes that
initialize during system boot use some of their rules during the startup process.
