show interface counters errors UnderSize field on 3750

nsysblh
Level 1
Level 1

I have a 3750 stack with a 2 way trunked ether channel fed from a 4507r. The 4507r is not reporting any errors. However, the show interface counters errors is showing a constantly growing UnderSize field. I don't think any packets are actully being dropped. No other error indicators are evident from either side.

Sofware version is: (C3750-I5K91-M), Version 12.2(20)SE1

Anyone else seen this? Looks like SE3 is now available, but the release notes don't mention this.

It is due to a limitation on 3750. Take a look at the following bug

Before the fix(which is in your IOS as well), runts would increment in show interface. Now it does not but undersize increments in should interface counters errors.
