TCAM holds the rules produced by applications, such as ACLs (Access Control Lists),
Quality of Service (QoS), while Router TCAM holds the rules for 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.
