Misterious Ethernet problem

Thu Jan 03, 2019 5:08 pm

Hi... I have a misterious problem...

in my network i use either ubiquity and mikrotik device...

when i connect a mikrotik NetMetal 5 in the same router/switch/toughswitch with an ubiquiti airmax M device (nanostation/powerbridge/ect.)

i have this situation:

if ubiquity device boot before mikrotik device... all is ok...
if mikrotik device boot before ubiquity device... ubiquity device ethernet port get "unplugged" ( I see it entering from wifi connection)
and it remain in this state until i don't reboot device in right order...

I tried everything... and in log file there isn't nothing...
I tried to change every parameter regarding ethernet side... nothing!!!

with airmax AC Device everything work fine...

someone have answer???
can someone testing it to exclude that it is only a my problem???

Thanks

What does the MikroTik log show after this happens? The issue is probably auto negotiation related.

IMHO it could be problem of STP/RSTP protocol. Switch it off and see what will happen.

Mikrotik log doesn’t show nothing error... problem regards ubiquity part... mikrotik cause it but it doesn’t know that problem exist...
