SG300 EeeLldpMultiNeighbours: Multiple LLDP neighbours on port

joopv
Level 1
Level 1

We have a SG300-28PP switch, running SW version 1.3.5.58

 

In the log we see at irregular intervals:

 

09-May-2018 08:22:44 :%NT_GREEN-W-EeeLldpSingleNeighbour: Single LLDP neighbour on port gi11 - EEE operational state can be TRUE

09-May-2018 08:22:11 :%NT_GREEN-W-EeeLldpMultiNeighbours: Multiple LLDP neighbours on port gi11 - EEE operational state is FALSE

 

Port 11 is a trunk to a Cisco AP1832I-E-K9 access point, managend by a WLC.  Nothing else is connected to this point.

 

After some troubleshooting it seems that another "alien" accesspoint in the neighbourhood is probably causing this beheavior.  The mac address points to this manufacterer / device:

Can anybody comment on this observation?  This is causing some issues...  And i also wonder if it's a security vulnerability.
