DTE/DCE DB60 Serial Crossover cables?

Unanswered Question

So I'm studying for my CCNA exam. I have a home lab with

2 Cisco 2514

1 Cisco 2611

1 Cisco Catalyst 2900

I can configure the Ethernet ports to work with eachother perfectly, but feel that I need to practice other technologies like Frame-realy.

I am having trouble getting my serial crossover cable to work when i connect the two 2514's together using my DTE/DCE serial crossover cable.

I tried setting the DCE end to clockrate of 5600 but the routers still say "is administratively down, Line Protocol down"

Any ideas/suggestions? I'm sure there is probably an easy solution, but i have been having a difficult time understanding what is missing.

Please go under the interface and unshut it;

interface serial 0/0

no shut

And please feel free to practice these:

HDLC Back-to-Back Connections


PPP Back-to-Back Connections


Back-to-Back Frame Relay
