10G SFP+ will not link up

DaltonC — Thu, 11 Nov 2021 23:15:00 GMT

I have a HP GEN10 ProLiant 380 that I am trying to link up at 10g. I was using an FS SFP+ module on switch side (Extreme Networks 10301 Compatible 10GBASE-SR SFP+ 850nm 300m DOM LC MMF Transceiver Module) and a HP 10G SFP+ on server side both SR. I had light coming through the fiber patch cable but the port would not go active, I could not even get a link light on the switch(X440-G2-48P-10GE). I made sure the port was enabled and was in the proper VLAN. Am I missing a port config to make the port active? Any help is appreciated!

Dalton,

This may be a silly question, but do you have the 10g license on the X440? What port are you using for the SFP on the X440?

Thanks,

Bill

Can you provide the output of "show license" and "show port <port number> information detail"

Thanks,

Additionally,

I'd check 'show port <#> configuration no-refresh' to make sure the port is configured for 10G. If it's not, you can use the following command to change the speed/negotiation on that port:

configure port <#> auto [on | off] speed <MBPS> duplex full

Also, 'show port <#> transceiver info detail' will show you if incoming light is being detected.
