Extreme switches 200 series SFP uplinks are not working

[Brandon_Cuellar]

Customer has a 220 series 12 port and 48 port and is trying to connect the 2 via SFP ports on 1/0/13 on the 12, and 1/0/49 on the 48, but still have a link state down. This is a flat network, only the default VLAN is there.
SFP modules are compatible (10301; 10GBase-SR). Can verify the SFPs are there on both switches.
Firmware is up to date to 1.2.3.5.
There is no serviceport address, but a network address is configured. Both ports are configured as a trunk with the allowed vlan 1. I tried setting the ports to 10G full-duplex, now currently have the speed set to auto with auto-negotiation on both ports. Also went ahead with the shut/ no shut on ports and still cannot get anything.

Additional information to add in:
SFP modules are 10301 (10GBase-SR SFP+). Using Duplex MM 62.5/125 PVC LC-ST fiber cables (orange). Are these cables compatible with the SFPs?

Hi Brandon,
Try using the firmware that I just sent to you. There's a known issue that's fixed with 220 and 10G ports. The ultimate fix is scheduled to come out in August.
Thanks
Brad

Hi Brandon, I am not able to enable auto-negotiation on SFP Ports of 210 switch. Since you are able to enable it on 220. Can you please help me with commands which you have used. Thanks in advance!
