We're working on a customer facing document explaining how TCAM is being used in ASR1000. Meanwhile, let me address this concern here. On ASR1000 TCAM is used as a resource for all classification clients, including ACLs, QoS, etc... Since XE3.10, when the system runs out of hardware TCAM, it will automatically switch to software TCAM. The HW TCAM can be monitored using the below CLIs: #show platform resources #show platform hardware qfp active tcam resource-manager usage The DRAM memory used by SW TCAM is shown under CACE component.  # show platform hardware qfp active infrastructure exmem statistics user | inc  CACE   In IOS-XE 3.10 onwards, when a large policy/ACL needs to be programmed and it does not fit into HW TCAM then the system will automatically move that policy/ACL to SW TCAM instead of rejecting the policy.   The below warning message will be generated: CPP_FM-3-CPP_FM_TCAM_WARNING F0: cpp_sp:  TCAM limit exceeded: HW TCAM cannot hold Class group <xxxxxxxx>. Use SW TCAM instead. There should be no service disruption, aside from the fact that HW TCAM will not be used (a potential performance impact). HTH, Michal ... View more
