C3750g etherchannel, jumbo, high numbers undersized frames

[katefuchs]

- Catalyst 3750G IOS 15.0(1)SE

- mtu 9000

- Etherchanel ports trunked, connected to EMC SANs (VLAN tagged) seeing high numbers of Receive undersized frames, no collisions, no errors, no discards

-VM hosts in access ports show no errors, collisions or undersized frames

Is this cosmetic? 

Everything is working, and performance is ok.

Thanks.

Haven't seen something like this.  Our 3750 in the DC are running 12.2(58)SE2 and our access 3750G are running 12.2(55)SE5.

3750 and 15.0(1)SE (including SE1 and the latest SE2) don't "mix", in my humble opinion.  Cisco has told me that the 15.0(2)SE is scheduled for release in August 2012 and will fix a few stuffs.
