Hi Jose,

Actually the IOS you are running is hitting a bug CSCee14673

Symptoms: A Cat3750 running 12.1(19)EA1a might continuously show the message:

%LINK-3-BADMACREG: Interface StackPort1, non-existent MACADDR registry for link 0

-Process= "", ipl= 4

-Traceback= 20AC84 188828 58ACCC 588F20 2D8020 2E00B4 2E2B80 2E2EAC 2B14E8

Conditions: This symptom is observed on a Cat3750 running 12.1(19)EA1.

Workaround: There is no workaround.

The bug is fixed in 12.2(20)SE and above.

So upgrading the switch will resolve the issue what you are observing on your switch.
