The show platform hardware ACL statistics utilization brief command displays this TCAM utilization per region for both ACL and QoS TCAMs. The command output shows the available masks and entries and divides them by region.

I?M usin pbr with "set ip Next hop". And need to know the use of tcam becuase this features support to 4096 entries for flow.

Do you know this?

[Collin Clark]

"The Catalyst 4500 switching engine supports matching a "set next-hop" route-map action with a packet on a permit ACL. All other route-map actions, as well as matches of deny ACLs, are supported by a flow switching model. In this model, the first packet on a flow that matches a route-map will be delivered to the software for forwarding. Software determines the correct destination for the packet and installs an entry into the TCAM so that future packets on that flow are switched in hardware. The Catalyst 4500 switching engine supports a maximum of 4096 flows."
