HexPOE to Cisco SG350x-8PMD Bandwith Problems only with sfp fibre connection

Mon May 30, 2022 4:19 pm

Hi,

im running into a weird issue.
When i connect my HexPOE to a Cisco SG350x-8PMD
with fs.com SFP1G-SX-85 Fibre Modules on both sides
I run into bandwith limitations for certain applications.
Downloads are limited to 1-3 MByte/s (10-12 with copper MByte/s which is my ISP max).
But https://www.speedtest.net/ shows the full bandwith.
NDI Streams Stutter, but RTSP works fine.

Using other network gear with the same modules with either the Mikrotik or the Cisco (or as a inbetween) works just fine.
Copper SFP Modules in the same Slots als works well.

When i was on Firmware 6.4 using torch on the sfp interface fixed the problem,
but with 7.2 this stopped working.

Hardware Offloading is enabled on all Ports.
I ran into the same Problem a few months ago and the soluten was to disable the Fast Track Firewall Rule.
I tried enabling it again, but that slowed the download down to 200 KB/s.

I have attached my config file, but all in all everthing is mostly on default.
config.rsc
Thanks in advance, i hope anyone has an Idea what might be going on here.
