i have a problem with rb260gsp , i have 3 devices on poe ports and 1 with no poe.
sxt ac holds 1gbit for just a few seconds and then drops on 100mbit. if i force only 1gbit , then there is no link. the cable is about 25m long and i did NOT have such problem with rb260gs using gigabit poe injectors.
the other cable is about 50m long and it holds 1gbit for about 30min or so, and then drops to 100mbit. this WAS happening with the 260gs too. this is non-poe connection. the other side is a tplink gigabit router. if i connect the cable to the hex router, it keeps gigabit forever, i was using this setup for 3 years with no problem with gigabit.
the only port that holds 1gbit is to a hex router but the cable is only 1m long.
all longer cables are outdoor ubiquiti toughcable pro. the cables are not grounded, but the 260gsp doesn't have ground connectors anyway.
this is log from sxt.
firmware on the gsp is 1.17
is the switch malfunctioning? is this a firmware issue?
if i connect the sxt to a poe injector to the hex router, it can hold 1 gbit for months, so it's not a cable problem.
thank you
