ExtremeXOS MAC Tracking

Hi all,

Currently seeing the following entries in my switches:

<Info:HAL.FDB.ExcssMACMove> Excessive MAC move notification from hardware encountered on slot 1. <Info:HAL.FDB.ExcssMACMove> Previous message repeated 6 additional times in the last 1500 second(s) 

However, there is nothing in the logs to indicate where it's actually originating from and what's causing it. I've tried adding a filter containing the following

FDB.MACTracking.MACMove FDB.MACTracking.MACDel FDB.MACTracking.MACAdd FDB.MACMove FDB.MACDel FDB.MACAdd 

... and I have enabled mac-tracking on ports 1-52, but it seems to not catch anything. Does anyone have any ideas on how I'd go about finding the source of this?

Thanks!
