100Mbps throughput on 1Gbps fiber connection
I'm running a throughput test with iperf between an M6100 with 2 physical fiber connections in a LAG configuration that run to a M4100 in a nearby building. I've checked the settings on both devices ...
Alright, so there's something wrong with the 1Gbps NIC in one of the laptops. We hooked up a new USB-C NIC and are getting the advertised speeds. Thanks for the replies.

I removed cos-queue min-bandwidth from the global config. Will test again and report back.
