Hello, I have a strange problem and would value any insight.
I can't get 10G port up between Aruba 2930F and Arista DCS-7050SX-64-R. SFP+ is used on both sides, Arista is using an original Arista transceiver, and Aruba is using Cisco transceiver with the command to use 3rd parties transceivers enabled. If I unplug the SFP from Arista and plug it to Fortigate, port comes up with no issues.
Logs show nothing.
When I try to force the port on Aruba 2930F, I don't even see option for 10G, only 10g auto. Tried to force SFP+ to 1G didn't work, tried 1G SFP on Aruba to SFP+ on Arista, also didn't work with negotiation or forcing.

On Arista, I can't force any port to anything except 10G, but transceivers are SFP+ from Arista.

Can't even do speed auto

Any ideas?
