Show controllers ethernet output

[jedavis]

I recently configured a network with a 4500 Sup7E and a 3560G with jumbo frame support.  I am trying to confirm operation.  On the 4500 this is straight forward using "sho int g0/nn count detail".  A portion of that output lists tx and rx frame sizes:

Port              InPkts 64        OutPkts 64    InPkts 65-127    OutPkts 65-127

Gi7/22              1631978          10708759          2220567           2087120

Port         InPkts 128-255   OutPkts 128-255   InPkts 256-511   OutPkts 256-511

Gi7/22                 4629             48616           118361             29112

Port        InPkts 512-1023  OutPkts 512-1023

Gi7/22               136697             50803

Port       InPkts 1024-1518 OutPkts 1024-1518 InPkts 1519-1548 OutPkts 1519-1548

Gi7/22              3075507           2083072                7                 3

Port       InPkts 1549-9216 OutPkts 1549-9216

Gi7/22             10165747               225

The 3560 doesn't support that command.  The closest I can come to finding the number of jumbo packets is "show controllers ethernet" (example below).  On the transmit side I assume that jumbo frames would be tallied in the "Too large frames" counter.  The receive side is a little more ambiguous.  There are 2 counters that seem to be duplicates, "Valid frames, too large" and "Valid oversize frames".  In operation they are not.  I am seeing the "Valid frames, too large" counter incrementing while the "Valid oversize frames" remains at zero.  The command reference doesn't help disambiguate this too much:

Invalid frames, too large:    The number of frames received that were larger than maximum allowed MTU size (including the FCS bits and excluding the frame header) and that have either an FCS error or an alignment error.

Valid frames, too large:  The number of frames received on an interface that are larger than the maximum allowed frame size.

Valid oversize frames:    The number of frames received on an interface that are larger than the maximum allowed frame size and have valid FCS values. The frame size includes the FCS value but does not include the VLAN tag.

What is "the maximum allowed frame size"?  The standard 1500 bytes or the 9000 bytes I configured?  Does anyone know how to monitor switching of jumbo frames?  Is there another command?
