Identify Packets to CPU

Hello all.  Is it possible to run a debug or create and ACL to see which packets are going to the CPU as opposed to being handled by hardware?  On the switch itself I only have two ACLs one for vty access and the other for snmp access.  Moreover, I'll "clear access-list counters" then run the command "show access-list hardware counters" and get output like below

switch_rm12#sh access-list hardware counters
 L3 ACL INPUT Statistics
     All  Drop:                     frame count: 3
     All  Bridge Only:              frame count: 0
     All  Forwarding To CPU:        frame count: 336
     All  Forwarded:                frame count: 5464
     All  Drop And Log:             frame count: 0
     All  Bridge Only And Log:      frame count: 0
     All  Forwarded And Log:        frame count: 0
     All  IPv6 Drop:                frame count: 0
     All  IPv6 Bridge Only:         frame count: 0
     All  IPv6 Forwarding To CPU:   frame count: 0
     All  IPv6 Forwarded:           frame count: 66
     All  IPv6 Drop And Log:        frame count: 0
     All  IPv6 Bridge Only And Log: frame count: 0
     All  IPv6 Forwarded And Log:   frame count: 0

What switch is this?

Its a layer 2, access switch.  Oh, I forgot to mention I don't have "log" configured after the ACL lines.
