Hi,
Im doing my first basic lab setup with my gear, and I cant get the
serial ports to stay up.
The lab test im doing is only a basic one:-
Router1 (R1) DTE END
Set Serial to 172.30.102.1 255.255.255.0
Set Eth0 to 172.30.101.1 255.255.255.0 >>> Switch 172.30.101.101
Router2 (R2) DCE END
Set Serial to 172.30.120.2 255.255.255.0
Set eth0 to 173.30.102.2 255.255.255.0
Set clock rate 56000
I have managed to do the config for this, and set no shutdown on R1
(Ether0 and Ser0) - R2 (Ser0)
Any ideas ?
Cheers

If you do a (show controllers ser 0) you may see something like this.
show controllers ser 0
CD2430 Slot 1, Port 1, Controller 0, Channel 1, Revision 19
Channel mode is synchronous serial
idb 0x8375F8AC, buffer size 1524, V.35 DCE cable, clockrate 128000
Also I can't a see clock rate command in the config.

I did sh controllers ser 0
And I have repeatedly set the clockrate but is not there when I do sh
run ?

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Your "show controller" output indicates that it is R1 that is the DCE
contrary to what your diagram indicates. Issue the "clock rate"
command on the serial interface on R1 and see if the interfaces come up
and ping fine.
