Netonix Forums

Hi,

My first site with a Netonix and I'm having issues with TX drops across Mikrotik VLAN. Screenshots below may explain it better. Really appreciate assistance to fix whatever I've done wrong as the drops are making latency and throughput lousy. Thanks

Please add Screen Grab of Device/Status Tab
A crude Network drawing showing where each port goes or does

Figure out why ports 6 and 7 pm;y show 10M links???

Also screen grab of each port detail stats

Ports 6 & 7 have radios are up a huge pole next to FM gear with a total of just 5 customers combined. To quickly resolve intermittent port flapping I've locked them to 10Mbps. The West nanostation on that pole still get occasional port flapping but regardless, the issue seems to be across the VLAN. Other Radios on different pole and have been re-cabled.

On the plus side, the WISP switch has successfully stopped port flapping I was still getting on the NE Rocket M5 (cable tested, recabled twice, radio replaced etc then we ditched the Digital Loggers 24V POE switch).

Latency from our NOC to the airfiber on the site is steady <2ms. Latency to the Mikrotik is often <2ms but has large spikes to around 50ms. Have updated airfibre firmware from release to the beta. Have tried flow control off. Have tried forcing the airfibre port to 100Mbps full duplex. Airfibre signal good (-58dBm, solid 256QAM giving around 135Mbps/40Mbps at 75% upload/download ratio) but speed and latency at this site are awful.
Have RB3011 and Airfibre, Airprisms on other sites without similar issues but I'm not running VLANs and WISP switches on them yet so I've done something stupid here

Please turn Flow Control OFF on the ports forced to 10M and possibly the AFX ports

I will look at it more tomorrow after Dentist appointment.

Would still like to see Port Details

Hi SIRHC, thanks for your help. I'm not sure what more port details would you like to see? There's no TX or RX errors reported on the Mikrotik. As per previous diagram, bar one old trango radio and the customer router everything is through one port (7) on the Mikrotik router with vlan isolation. VLAN ID 202 is the Airfiber 5x backhaul. VLAN ID 203 is the reserve backhaul...etc etc.

I've disabled flow control on the netonix switch ports facing the AF5x and the two (north and south) nanostation m5's running at 10Mbps.

Also disabled flow control on the AF5x at the tower (as in the radio config).

I had a good think about this last night and changed my google search! I think it's solved.

set
ether7-Netonix queue
=ethernet-default


ethernet-default queue type is pfifo but size is changed from 50 to 200.

I've re-enabled flow control and ran some btest/iperf tests. Performance miles better!

Only way I can find to reset vlan counters is to restart the mikrotik so I'll schedule that for the wee small hours.
