Nray w60g station hangs and generates unknown traffic

Wed Aug 04, 2021 4:48 pm

Hello!
I facing problems with two links of wireless wire nray:
- Links is 700m and 3km. Connected as station->ap->switch->ap->station.
- Carries same traffic (failover while optic fails)
- POE is good: one link at 48v 0.5a/another at 24v 1a (worked flawlessly with previous gear)
- Swapping station/ap sides does not change situation, only station side hangs.
- Two stations hangs at the same time, brings down ethernet and when port goes up there is no traffic until reboot by watchdog.
- Management is not accessible via http/ssh/mac-telnet. Not traffic coming from station side.
- Station is connected to ap, but if I reboot ap it wont connect until station reboots.
- Switching offload and learning does not help. STP, loopdetect and multicast is off.
- Tried firmware 6.47.10, 6.48.2, 6.48.3, 6.49beta54 (watchdog helps to reboot), 7.1beta6 (hangs totally, watchdog didnt help at all, only power cycle)
- Even if I enabled storing supout.rif on watchdog page, after reboot there is no such file. Logging to disk also did not reveal anything.
- Before hang w60g interface generates about 400k of traffic with ethertype=4 between wireless side macs (I changed bridge mac not to match it, clearly traffic is directed only to radio interface)
- Captured traffic on w60g interface via packet sniffer & wireshark. Seems unknown to me, but src and dst macs is w60g radio interfaces.

Anyone can help in this situation?

Second link is now inaccessible (needs power cycle with 7.x firmware) but config almost same except ip addesses.
Default preconfigured config after reset (with only management vlan added) hangs too.
Link passes only tagged frames, untagged frames disabled by switches on both sides.

On this graph each spike represents device reboot.

Re: Nray w60g station hangs and generates unknown traffic

I cant' see anything strange on your export,
I have 4 links (no one in same pole, 2 near 300m, 1 900m, 1 1200m ) with 6.47.10 (but without "software" vlan) and I do not have any problem till now...

You sure no other operators or hobbyst use same frequency near your?

Absolutely sure that there is no other radio gear close than 200m on any ends of the link, absolutely sure that there is no 60ghz gear closer than 1km at 2 of 3 stations.
Selecting different frequency also does not help.
I think that passing some broadcast/multicast (since there is no proper unicast packets without failed optics) packet brings down links.

Re: Nray w60g station hangs and generates unknown traffic

For me, one nRAY constantly loses signals every few seconds. There were also problems with the other nRAY. I tried everything, nothing helps.
Honestly, there is no Mikrotik W60G that would not have been a problem (so far the exception is the Cube60ac, but I think it's a matter of time).
I am determined not to buy any more Mikrotik antennas. Today I took the warehouse antenna W60G to the customer and offered 1) the customer configures it himself and serves himself 2) we put another manufacturer. The customer stayed at Mikrotik. Accordingly, it is no longer our problem.

Re: Nray w60g station hangs and generates unknown traffic

More results:
100% default configuration (reset to defaults with both sides, preconfigured bridge with ip 192.168.88.2 and 192.168.88.3) does not help.
Station hangs/reboots with "router rebooted without proper shutdown".
When station in hanging state I can reach it via wireless side if I disconnect wired link. Even after enabling wired link theres is no connectivity until reset.

Are you sure you have not got a power supply fault or a faulty cable?

100% sure. Before nray there was no problems with this cables. Tried diffеrent POE - 24/1a,48/0.5a,56v/1a. Tried POE switch (no errors on port, nray just reboots).
Reboots can avoided by disabling W60G interface or disabling traffic on ethernet or W60G side.

Which devices? All four?
I think there is software problem (as hanging only one, station side), warranty will not cover it. Or it does?

Routerboard screenshots for example:

Already updated bootloader with beta, was stock in the beginning of testing.

Is it only locking up when you connect to your network?
A few others have had problems with them being unstable and they swapped them for the old version and everything worked fine.

Yes, only when connecting to network.
Is there "old version" for nray? Which version I must request from dealer?

Its not an Nray its the old version LHG60G which most go back too.

I know there is a simular fault on the Ubiquiti 60G causing the units to lockup, its something to do with how the network is setup (routed or bridged).

One of the guys on the ubiquiti site wrote:-
There's something running out of boundaries, too many ARP-MAC entries, something low on TCP/IP stack due to memory constraints... Definitely, all reports of these problems here on forum have been solved when flat bridged network was changed to routed. All of them.

Some customers want VLANs and loading them with tons of MACs inside. What should we do in this situation?

Also tried setup with eoip inside wireless: ethernet - bridge - EOIP - w60g-interface - w60g interface - EOIP - bridge - ethernet. Bridge learning disabled.
Still reboots, so maybe problem related to bridge itself, not w60g link.

Does it crash if you only have one side of the network connected?
Could it be a loop?

Yes. This links acting as wireless backup for fiber. Only one side is connected (other disabled until fiber link is working).
Loop inside customer vlan can exist, we can't detect it. But customer vlans are bandwith-limited.
But only vlan, handled via device CPU is management and it's 100% without loops.
Traffic entering this links is mostly broadcast and unknown/unlearned unicast. Maybe some multicast, but it disabled on switches.
Here is graph of such port for 3 days:

So if you disconnect your fibre link and just use your wireless link does it still crash?
