I have a HP V1910 Switch in my office. I have set up monitoring via SNMP on my local Zabbix server, and everything looks really good on almost all ports (for example, when I use iperf to test throughput or just send a big file between 2 machines connected to 2 different ports).
There is one port though that gives me very odd (too low) figures on incoming and outgoing traffic, even though it gets plenty of traffic, my local PoE Switch (UniFi Switch 8 POE-150W): https://www.ubnt.com/unifi-switching/unifi-switch-8-150w/
The latter is sending all the traffic that goes to the wi-fi access points. We have a lot of users connected via wi-fi, so 20Kbps simply does not make sense.
What I really want to do is monitor the traffic on this port, so I've set up SNMP on the UniFi switch in question as well, but it's not exactly the same.
Any advice? Could it be that when 2 switches are interconnected in this way the port starts behaving in a special way? Everything has a very default configuration, no VLANs.
