SDN/SDDC Retreat in Miami, Florida (November 4th-6th)
Separate SDN hype from real life!

Simplify your lab work

If you do a lot of tests in a router lab, you're probably getting upset when you have to retype the login and enable password whenever you log into a router. What I do in my labs is to disable VTY login, set the default privilege level to 15 and disable exec timeout (to stop the router from terminating my session).

line con 0
 exec-timeout 0 0
 privilege level 15
line vty 0 4
 exec-timeout 0 0
 privilege level 15
 no login

Obviously, this would not bring you additional points on the CCIE lab exam :)


  1. I also like adding "transport preferred none" so the router doesn't try to resolve typos as commands. Using this command you can still ping by name.

  2. Also fix the logging output so it restores your typing.

    line xxx
    logging synchronous
