Hello,
I have a CSS610-8G-2S+ connected to a CRS310-8G+2S+ via S+RJ10 on CSS610 to RJ45 port on CRS310, at 2.5Gbe via CAT6.
On the CS610 I also have a PFsense internet router connected at 1Gbe and on the CRS310 a Linux box connected at 2.5Gbe.
When I run a speedtest from the Linux box, downloading reaches line speed (1Gbe) and no TX or RX pauses are seen on either Mikrotik device.
Upload speed however, is stuck at 200-300Mbps and I’m seeing tons of TX Pauses on SFP+ (w/ S+RJ10) port on the CSS610 but no RX Pauses on the CRS310's corresponding RJ45 port.
I can reach full 1Gbe download and upload if I connect the Linux device at 1Gbe instead of 2.5Gbe.
What can I do to reach full upload speeds from the 2.5Gbe device ? Am I not configuring Flow control correctly ? Why am I only seeing TX pauses on on device and no RX pauses on the other ?
Sorry if this was solved somewhere else, I've read some similar topics but none seem to point at a solution ( viewtopic.php?t=182691 and viewtopic.php?t=183165 )
Thanks
