We replaced some 3550's with 3750's and now I am seeing input crc errors on multiple ports that are connected to 2950's. I have tried all combinations of duplex/speed settings and replaced cables, I have even moved ports. I keep getting input crc errors building on the 3750 interfaces.
There is a bug on the 3560/3750 (plus 2970 etc) where interfaces configured as 802.1q trunks (or ports configured with Voice VLANs) display inconsistent stats.
For trunk ports or access ports configured with 802.1Q tagging, inconsistent statistics might appear in the show interfaces counters privileged EXEC command output. Valid 802.1Q frames of 64 to 66 bytes are correctly forwarded even though the port LED blinks amber, and the frames are not counted on the interface statistics. There is no workaround. (CSCec35100).
I saw this earlier in the year with Voice VLAN's configured (Nortel IP Phones) - I actually saw the counters CRC increase and the orange LED blink on the ports.
This issue is resolved in later code (12.1(20)EA1 and later).
