We have the CISCO SG300 28 port switch. I have noticed some log warning that appear like this:
2147451055 2017-Aug-30 11:35:01 Warning %NT_GREEN-W-EeeLldpMultiNeighbours: Multiple LLDP neighbours on port gi12 - EEE operational state is FALSE 2147451230 2017-Aug-30 11:35:01 Warning %NT_GREEN-W-EeeLldpSingleNeighbour: Single LLDP neighbour on port gi12 - EEE operational state can be TRUE 2147451405 2017-Aug-30 11:29:35 Warning %NT_GREEN-W-EeeLldpMultiNeighbours: Multiple LLDP neighbours on port gi12 - EEE operational state is FALSE
My initial research yielded that this is likely caused by a user/port/LAN that has multiple devices on it. That is true in my case. Port GE12 is connected to one of our offices that has limited ethernet jacks, so we run separate ethernet cables from the desktop and IP phone into an unmanaged switch, and from there they become one, connecting to a single ethernet jack. (to help explain this I have included a diagram below)
Assuming that this setup is what is causing the error I am wondering how I can resolve it. Is there a specific setting that I can configuration that will be more optimized for the way port GE12 is setup?

Hi,
My name is Nikola Butlev an d I'm Cisco Employee. Does this issue persist if you disable EEE?
BTW is the firmware version on your switch 1.4.11.5?
Thank you,

Hello,
On the affected switch I am currently running 1.4.11.5 and when you refer to EEE, I am thinking you mean green ethernet? it is disabled.
I haven't had this issue since I originally created the thread some time ago, so i am thinking I at the time updated to the latest firmware or I disabled the green ethernet...sorry i cant remember.

Hello,
I have the same problem experienced but I have solved it with this try. "Multiple LLDP neighbours on port fa48 - EEE operational state is FALSE" And
"Single LLDP neighbour on port fa45 - EEE operational state can be TRUE". But my network diagram Cisco port Access VLAN to Managed Switch CCTV but it's running in VLAN1 only. Refer the messages, I notice that on Cisco switch port changed mode from Access to Trunk automatically and learned so many mac-address from Cisco port. This is because CCTV switch are connected to many devices.
no eee enable
no eee lldp enable
no lldp receive
no lldp transmit
Last changed switch port mode to access again.
switchport mode access
