As the topic says, I have a CRS125-24G-1S-2HnD that I am trying to use strictly as a switch, with no routing going on. I have everything configured and all of my ports are communicating, but I am not getting anywhere near the speed I’m supposed to be via this connection. All ports are negotiated at full duplex 1Gbps, and performance without this switch in place is where it’s supposed to be. What’s strange is clients who are on the same switch perform fine, but having to make a connection to something outside the switch suffers terribly. Not sure what I’m doing wrong so any help would be appreciated.
iperf results for clients on the same switch:
------------------------------------------------------------

The speed=100Mbps concerns me but from what I can find that is just the default speed if auto-negotiate failed. Winbox shows all ports are linked at 1Gbps.
