BE800 SFP+ 10Ggb/s backlink downspeeds to 1Gb/s
BE800 SFP+ 10Ggb/s backlink downspeeds to 1Gb/s
I have two BE800 connected via SFP+ in a main router/ access point configuration.
I have purchased and tested with 2 x Finisar FTLX8574D3BCL SFP+ modules connected with 15M OM3 Fibre.
When this kept dropping to 1Gbps I purchased and tested 2 x Ampcom AM3-SFP-XG-SX-MM850 SFP+ modules connected with 10M OM5 Fibre .
In both cases they connect fine at at 10 Gbps Full Duplex but if left for a couple of hours the link will downspeed to 1 Gbs Full Duplex .
I dont know how long this takes because it isnt reported or recorded in the log, and the Tether app does not report actual interface connection speeds (!).
I learn about it when my NAS copy speeds drop from 560Mbps to 113Mbps or when I log into the web interface.
The only way to restore full speed is to disconnect the fibre and reconnect or reboot both ends of the link.
I assume this may be a power saving feature but there needs to be a way to bring the link back up when there is activity on it.

Not sure if this helps, more confirms.... I'm on 1.3.2 (2x be800v1 connected by a 10GbE SFP+ to SFP+ Active Optical Fiber Cable) and I've having the same or similar issue. Starts out at 10gbps, and at some point drops to 1gbps I was searching the web to see what could be done about it and I found this thread.
