snmp interface bandwidth throughput
I monitor the external interface bandwidth throughput with snmp. I noticed each time the traffic goes past 400-500Mbit/s, my snmp agent (zabbix) do not get reply packets (i guess) as the graph is missing data.
Original i was monitoring a M370 cluster and thought i might be a HW/cpu performance issue, but now this cluster is replaced by a FireboxV, and i see the exact same result with this firebox.
The box has allocated 2 x vCPU Intel(R) Xeon(R) Gold 6234 CPU @ 3.30GHz and 4GB memory with a 10Gbit/s uplink. CPU usage is under 5% on each core.
Why do the firebox drops snmp packets when traffic reach the above interface speed?
