[Mehmet Can]

Hello Everyone,

I have one of 3850-48XS-S. I will configure for our customer. But i saw in the running confing non physical Ten1/1/1-16 interface ports. What are these ports? What does it mean?

Thank you.

do you have a free module slot , they may be there for when a module gets added in the future ,the software may already be prepped same as stack module when you see the 10gb ports but there not active till you actually insert the module

Hi Mark,

I saw on the internet octopus module/cables for 40G ports. We have 4 pieces 40G ports on the 3850. If we want use octopus cable and we can divide each port into 4. :)

For example:

Sorry what do you mean divide the port into 4 , is this a separate question for the original post ?
as far as i know and i dont have 40gb on my 38s only on my 9ks , these ports are fixed ---
