I have some strange issue with 4 APS working in mesh: 2 APS as root with ethernet link + 2 APS as non-root without ethernet link. All of them configured with one mesh ID.
Every few seconds in root APS in CLI connected trough RS232 I see this warning message:
0| ports.c:1959 Warning: GMAC Rx Error on port ge1: [10] Lenght Mismatch
Besides, everything seems working well.
WING 5.8.4

It is seems to be a result of improperly configured mesh configuration?
Any ideas, why I have this warning?

Hello,

Sorry but I don't have them.

Any ideas nevertheless?

Hi Aviv, 

GMAC is gigabit media access control. 
The message is referring to AP interface GE1 and not interface radio therefore I believe it is not related with Mesh. 
If I understand correctly, it is referring the AP interface GE 1 receiving mismatch frame ethertype/length.  
I will suggest first to check cabling, connector, switchport configuration and AP interface GE 1 configuration. 
AP techdump file will be very helpful for further analysis.
