**Edited to include correct model, apologies. Hello all, I have a strange issue I wanted to put out some feelers for. I have a MS225*-24P with SFP+/10Gb uplink to WAN router (have tested both pfSense and SonicWall Supermassive) and several clients connected downstream. Issue: 1) Clients connected via copper GbE lose about 300-400Mbit of WAN throughput if connected to the MS225, speeds top out about 650Mbit/s. However, I have another 10Gb SFP+ downlink from the MS225 to a desktop client for testing - and full WAN speeds are achieved. Also, the same copper GbE connected directly to WAN router (bypassing MS220) achieve full near-gig speeds. It seems there is some issue between the SFP+ interfaces and the the GbE interfaces on the switch? Let me know if any of you have experienced this. Thanks!
