Hi All
I have configured sna before and have in the past connected the sna controller to the router with a db60 to rs-232 cable. This seems to work ok on a 2600 and this is the output I have from sh int
Serial0/1 is up, line protocol is up
Hardware is PowerQUICC Serial
MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation SDLC, loopback not set
Router link station role: PRIMARY (DCE)
Router link station metrics:

N1 (max frame size) 12016 bits
N2 (retry count) 20
poll-pause-timer 10 milliseconds
poll-limit-value 1
k (windowsize) 7
modulo 8
sdlc vmac: 4000.9999.01--
sdlc addr C1 state is CONNECT
cls_state is CLS_IN_SESSION

RNRs 8994503/0 SNRMs 230/0 DISC/RDs 38/0 REJs 0/0
Poll: clear, Poll count: 0, ready for poll, chain: C1/C1
This 2600 router connects ok, but at the moment, I am trying to connect a 3600 router to a controller although the controller is not connected yet. When I do a sh int on the 3600 I get
Serial1/3 is administratively down, line protocol is down
Hardware is M4T
MTU 1500 bytes, BW 2048 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation SDLC, crc 16, loopback not set
Router link station role: PRIMARY (DTE)
Router link station metrics:
slow-poll 10 seconds
T1 (reply time out) 3000 milliseconds
N1 (max frame size) 12016 bits
N2 (retry count) 20
poll-pause-timer 10 milliseconds
poll-limit-value 1
k (windowsize) 7
modulo 8
sdlc vmac: 0000.0000.00--
Last input never, output never, output hang never
Last clearing of "show interface" counters 00:33:01
Queueing strategy: fifo
Output queue 0/40, 0 drops; input queue 0/75, 0 drops
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
0 packets input, 0 bytes, 0 no buffer
this shows the int as dte where as on the one above shows dce. When I try to enter the "clock rate" command to issue the clock rate I get "%Clock rate is ignored on DTE interfaces. ". How do I change this to dce, does the controller have to be connected first or is there a command for this. I didnt seem to need to do this for the working 2600, I just enter the clock rate command and it worked fine. Any advice would be appreciated.

Karl,
For starters your 3600 s1/3 says it is Administratively down, you will need to do a 'no shut' on the interface to begin.
For the DCE/DTE it is based upon the cable type. Cisco can sense which pins are wired up when you plug the cable in. You currently have a DTE cable plugged into the router. You will need to go and purchase a DCE cable.

Hi Ron
That is perfect.. I will go and purchase one... thanks for the answer.
