3850 data sheet

Datasheet says it supports both 1/10, but when configuring it, the only interface shown is the TenGigabit.  Is there anything that needs to be done to switch from 1 to 10, or is this automatically detected?

Let me bring your attention to this document wherein it is explained that 10 GB ports do not support the speed or duplex commands because they support only 10 GB.

You should, ideally, contact TAC (hopefully you have a SmartNET contract on a switch this important you your network!) to verify the information for the specific module you're using.

Are you using the correct SFP+ for 10G?

I'm using GLC-SX-MMD= SFPs.  I only need 1G interfaces.

I found this http://www.cisco.com/c/en/us/td/docs/interfaces_modules/transceiver_modules/compatibility/matrix/GE_Tx_Matrix.html#_Toc457217048

I see my transceiver listed so it should work, but there's still the question why I don't see the Gigabit interface vs TenGig when I plug in the 1G SFPS.

Do you mean in the cli you only see ten gig ints? Have you checked the actual speed of that interface when you put in SFP for 1 gig?

Yes on the cli. Do you mean checking it by 'sh int status'?

Hi There,

Check #sh interface capabilities and #sh int status to verify once the physical connectivity is established.
