Im working with my server team and they are requesting i change the port setting on the 3350 to auto speed. I understand that gig ports can only be set to full. But I am used to seeing "auto" in the show interface command...but i am not seeing it here. Nor is the configuration showing auto. Is this becuase it is the default?

when you type in the command: (show interface status) you will see the Duplex and Speed setting for each port.
Hope this helps.

Sorry I forgot to add that this is a default and what you have displayed is correct.
"Full-duplex, 1000Mb/s, media type is 10/100/1000BaseTX" the (show interface status) command will display the Duplex a-full and Speed a-1000.
Hope this helps. Please rate it if it does.
