Viewing TCAM Utilization
The device architecture uses a Ternary Content Addressable Memory (TCAM) to 
support packet actions in wire speed.
TCAM TCAM holds the rules produced by applications, such as ACLs (Access 
Control Lists), Quality of Service (QoS), IP Routing and user-created rules.
Some applications allocate rules upon their initiation. Additionally, processes that 
initialize during system boot use some of their rules during the startup process.
To view TCAM utilization, click Status and Statistics > TCAM Utilization.
