I bought several 2500 series routers off ebay to start a lab. Some serial interfaces are DTE, and some are DCE. Is this configurable or hard coded???

I searched high and low, and couldn't find the answer.


Thanks guys
 
Hello
This feature isn't hard code.For labs it's you who gives the clock rate command,for production it's another story.
Good luck
 
I go into serial0/0 and input clock rate 64000 I get the message Can't configure clock rate on a dte interface. I tried switching the cable to the DCE side, and get the same results.

thanks
 
Have you tried on another interface?
Maybe there is a fault with the interface or cable?
Try switching the cable and try the cable on another interface.

Normally once the DTE/DCE cable is connected and the clock rate is set you shoud see the interface as showing:
Serial0/0 is up, line protocol is up

If it is:
Serial0/0 is down, line protocol is down (down, down)
Then there is a problem with the physical layer (cable or connectors)

If it is:
Serial0/0 is up, line protocol is down (up, down)
Then there is a programming fault.

Type: show controllers serial 0/0
to see if it is DTE or DCE

Guys

Let me see if I understand this....
If i connect the dce end of the cable to a serial interface, that will make that interface dce?

The state of the interface is a function of the cable type plugged into it?

I thought I tried various combinations with several interfaces and routers. But if you guys confirm the above is true, I'll go home tonight and switch cables and interfaces.

Thanks

Yes.
