I am having a hard time bringing up the serial interfaces in my home lab. I have 2 routers each with 2 serial interfaces, I have assigned (on router 1) serial 0/0 10.1.139.253 255.255.255.0 & serial 0/1 10.1.140.253 255.255.255.0 and also use the no shutdown command. but if i use show ip interface brief it shows status down, protocol down. what am i doing wrong? I am new and trying to learn, so ur help will be appreciated. thanks
You are very very welcomed, this is really a nice start, and please keep up the nice work :)
As for your earlier question, the answer is yes the router can be DCE for a certain interface and DTE for another, as the DCE/DTE stuff is per interface characteristics, you just need to make sure that the DCE part of the cable is connected to the interface having the clock command under it.
