XS716T Switch. Forcing a port to 1Gbps for LACP. Documentation doesn't show it possible?
Hello,
great community. have a quick question. I am going to have to configure a LAG between (4) ports on the XS716T and (4) ports on a 1Gbps switch. I understand that all ports must be the ...
By the IEEE 802.3 design, 1000Base-T (and ie. 10GBase-T) auto-negotiation is mandatory. Properly compliant IEEE 802.3 hardware will send and respond to link negotiation information in link pulses. Anything else is a violation of IEEE 802.3 - a standard made long before 2018.
Very different is the situation when it comes to SFP and SFP+ - there is no auto negotiation, neither on the SFP/SFP+ interface, nor on a fibre link. Therefore, you won't be able to link up a GbE switch with SFP ports to a 10GbE switch with SFP+ ports.

Thanks so much for the reply. I am just trying to create a 4-Port LAG via the copper ports for now. I know it's not the most elegant situation but we have some open ports so why not. Will give it a go on Auto.
