Tl;dr; I have two FreeBSD systems attached to a Cisco switch, there should be multi-gigabit connectivity, but only seeing 1Gpbs. Each system is trunked, vlan interfaces on the underlying interface.
I have an older Freebsd 11.x system with a 10gbe interface, There are a collection of vlan interfaces on it.
I have a newer Freebsd 12.3 system with lagg across two 1gbe interfaces. There are a collection of vlan interfaces on the lagg.
I would _expect_ to be able to get 2gbps, or just shy thereof. But, using iperf3 shows me the same ~940 Mbits/sec that I get when coming from a system a couple switches away on a single gigabit connection.
Looking on the Cisco switch, the port-channel (connected to the lagg) claims "BW 2000000 Kbit/sec”.
Happy to share config with anyone who may be able to help, but won’t paste it all here.
