How to configure 1G BaseT SPF in Summit X670-G2

[John_Dave_Thurl]

Hi im using a X670G2-48x-4q with the firmware v15.7.1.4

I want to use some 10/100/1000 BaseT SPF but they wont show link.

I have configured the with the command
"
configure ports x auto on speed 1000 duplex full
"

can you help me out is there somthing missing in the configuration?

Yes, as Jeremy suggested, make sure that both sides are either LR or SR. If you mix these, the link will not come up and you may even have the ability to damage an optic due to signal strength.

Did the port come up when the notebook was connected? If so, then make sure your gbics match. I know, I know... just humor me, I'm sure you've already double-checked. What is the next device upstream? I had issues getting a black diamond talk to a Cisco 9K last week and wound up having to move the circuit to a 3850 stack.

Hi, thanks for your comments!

@Venko
i cant set a 1G port on autoneg off. it is recommenced for 1G

@jeremy
the port informations are ok. SFP status is ready and the port is enabled but not active.
i just connected the port to an notebook with 1G NIC for tests.

@hasan
it is not possible to use the medium command on a non combo port.

Try show port xx transceiver information detail to see if the gbics are supported. Also, be aware that it may show unsupported if the gbic does not support displaying information about its' properties. You can also try show port xx information detail and see if there are any messages related to the port being shutdown by the switch, disabled, etc.

Are you connecting to an ISP, is that why you hard set the port properties?
