port drop every 8 minutes

[Mike]

I have a port that drops every 8 minutes like clockwork for several hours now. No watchdogs or anything running. Is there anything specific to that 8 minute interval with Netonix? If I reboot in between it still keeps the original 8 minute drop time frame which is weird.. Just updated to the latest firmware still same.

This is most likely not a Netonix issue but lets look at the possibilities.

I want to point out your information is vague at best, how about some more information becuase my crystal ball is in the shop:
Switch model?
Switch Firmware version? (If not v1.4.7rc14 then upgrade before we proceed any further)
UBNT radio model?
POE option you are using to power this radio?
Length of cable to radio?

Have you verified the radio is actually rebooting by checking up time?

The fact that it is 8 minutes would indicate a watchdog either on the switch or on the radio but you say there is none setup on the switch or the radio. - VERY ODD

Possibilities and testing methods:
1) A Watchdog but you say no??? - DOUBLE CHECK SWITCH AND RADIO JUST FOR GIGGLES
2) Something with the switch port - TRY A DIFFERENT PORT IN SWITCH
3) Bad cable or end and you are getting a disconnect - HARD TO BUY THIS ONE AS THE PRECISE 8 MINUTE CYCLE
4) Bad radio - SWAP OUT RADIO

You can see the 8 minute drop is constant even if I reboot or do anything in between. The big reds that I marked are me upgrading firmware and rebooting and trying things.

I do have the latest rc14 on it. Its a Ubiquiti AC620 powered by the switch itself. Been up for a year no issues until last night when this happened. Cant be watchdog because it continues that 8 minute clock time even if you reboot stuff between. I have no watchdogs running. The radio stay up and does not power off its just the Ethernet. ws-6-mini switch.

There is nothing in the switch that power cycles devices unless told to in the Watchdog or scheduled Port bounce.
(CHECK BOTH PLACES IN THE SWITCH UI UNDER TOOLS TAB)

As I said try another port in the switch, see if problem follows to other port in the switch.

[sirhc]

What is powering the WS-6-MINI?


Post up Switch Tabs:
Status
Ports
Tools/Watchdog
Tools/Port bounce
Device/Status

Its 2 hour drive and a mountain climb in deep snow so Im trying everything else first. radios are staying powered its only Ethernet drop. its a power supply from Netonix for the minis but this is not a reboot power thing its Ethernet drops only. I am pinging the radio from other side flawlessly so radio doesn't drop. The 8 minute thing is weird and I checked all watchdogs and there is none running.

OK so the radio stays up, does not reboot just Ethernet link drop.

Tell me you have the port in the switch set to AUTO and the radio port set to AUTO correct?

NEVER HARD CODE SPEED DUPLEX

[Mike]

yes both auto showing 1 gig I have those screenshots. Watchdog and Port bounce have nothing they are not on.
