Subject: RE: Serial0 is up, line protocol is down!
I'm doing this loopback test on the back side of interface, its aphysical
loop.
earlier I thought it could be because of different protocols being used at
the other end of the serial link.
thanks.

The line protocol down means that the other end are not sending keepalives .
So yes its datalink (correct me if I am wrong ).
If you are using back to back is there clocking on your dce side ( do a show
control serial 0 )
look for dce .
If not check that your NTU (clocking device is plugged in)
could also be a wrong encapsulation type that was set

You're looking for the network layer protocol. It depends on what protocol
you're running, i.e. HDLC, PPP, Frame Relay, ATM... In the case of Frame
Relay, you can try "debug frame-relay lmi" to get a look at the protocol
messages. Look at the "myseq" and "yourseq" parameters and see which one
