I’ve recently deployed LibreNMS in my network and am receiving port utilization alarms during my nightly backup cycle. When I view the “port” that is triggering the alarm it is a vlan (interface, I’m assuming) on one of my Cisco Catalyst switches. Total traffic on the port reaches about ~1.3Gbps. When I check in port settings it is showing the interface speed as 10Gbps. While 10G isn’t what the backplane can handle I’m fine with this detection, what I’m not understanding is how 1.3G is over 80% of 10G.
I’ve found another post about disabling alerts for loopback interfaces where it is recommended to turn alerts off and I can do that but if there is any way to fix this I would appreciate the help.
