I have setup a Cisco lab and attempting to create a WAN lab. I have 2 Cisco 1700 routers connected to each other through a DCE/DTE cable. I am attempting to mimic a WAN connection between the two routers.

I have the DCE setup for clocking at a clock rate of 64000. I am unable to bring the serial interface up. Both status and protocol are down.

I have run the 'no shutdown' command on the serial 0 interface on both the DCE and DTE routers. Am I missing something? Is there something different in bringing up these connections in a lab environment using DCE/DTE?


Cheers,

I have looked at this problem from every angle.

Verified hardware is functional
Entered the following:

R1(config-if)# interface serial 0
R1(config-if)# ip address 172.17.0.1 /16
R1(config-if)# clock rate 64000
R1(config-if)# no shutdown

I know for a fact this is correct! Still no go!!!

zIPPY,

Try setting your encapsulation to ppp on both sides, also check the controller/interface (sh interfaces).

Let us know of your results.

I've set both sides to use encapsulation ppp.

I ran a show ip interface brief which gave me the following for the serial 0 interface.


Status: down Protocol: down

OK?: yes and method: manual

Hi Zippy,

Could you copy/paste that show ip interface brief output here.

By the way, the line:

[code:1]R1(config-if)# ip address 172.17.0.1 /16 [/code:1]

Should be done like this:

[code:1]R1(config-if)# ip address 172.17.0.1 255.255.0.0 [/code:1]

I'm sure you know this but just in case.

S0lo,

Do Cisco routers not like the prefix notation for the subnet? I wonder if that is my problem. But I'm pretty sure when I entered the subnet mask I typed it out. I'll copy/paste the output this evening when I am home.

Thanks!!
