Some Cambium devices do not like surge suppressors. That is why I created the CAT6 line of product.

I would try the following in this order. (1) Bypass the surge suppressor (possible, especially if you're out of lightning season). (2) Use the PoE brick and plug into a managed switch port so that you can monitor traffic and errors both on the Ethernet switch side and the PTP450 side. Use PingPlotter (free version) or any other graphing ping tool and ping both the switch and PTP 450 at the NOC. Compare traffic, graphs and SNMP results from all these sources. Set the Ethernet speed and duplex modes on both devices and allow to run. Noting the time when you made the changes. Clearing any errors prior to making the changes as well. See if the CRC errors or other are increasing significantly on the current settings. Continue making the changes and monitor errors. Which ever one is increasing the fastest (the device), most likely may lead you to the source of the problem. Check your syslogs as well. See if the syslogs are showing any activity or issues from the PTP450 and the switch. Check your RMON. If you are able to monitor Netflow or S-Flow on the switch. See what traffic is coming through. Use a tool like OPManager (free or trial) to monitor the switch and see what their built-in tools / graphs for traffic congestion shows. Make sure nothing else on your network is accessing your switch or PTP450 BH at the NOC. Regards. On 08/11/2018 11:45 AM, Sam Lambie wrote: Guys, I have a backhaul that is driving me nuts. We have a 6.9 mile link from our NOC to the site. The Master at the NOC is exhibiting ehternet errors up the wazoo when loaded. During prime time, we are pushing about 70 mbps through the link. Wirelessly, everything is perfect, 106/19 with 99% link quality and no errors on the RF side of things. Yesterday I replace the main cable up to the radio, replaced the surge suppressor and even plugged in a Cambium power supply to bypass the CMM. Then I moved the LAN cable from it's switch to a new switch in case that port was choking, nothing has made a difference. I even changed out the radio for about an hour a few days ago with no difference. Frame utilization has never spiked beyond 68% but the CPU is pegged during peak time at 100% Any suggestions? or need any other screen shots? thanks! -- -- Sam Lambie Taosnet Wireless Tech. 575-758-7598 Office www.Taosnet.com -------------------------------------------------------------------------------- -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
