The 3640s... I don't have to.

The clocking is always provided by the DCE side therefore it has to be set.

Which plat forms have you found that you don't have to set the clocking for a DCE interface?

Yeah... I ran into the same issue before. I had to set the clock rate on the DCE side as Scott said. I noticed that it was only with the 2500/2600 series... Why is that?

 

Thanks,

Dan

If you're connecting two 2500 series devices back to back, you'll need a clock rate on the DCE side.  In addition, if you aren't using a frame switch in the middle, you'll want to do "no keepalive" on both serial links.

 

As a note, in your configs below, those interface types aren't what you'd see on a 2500.  :)

Here is a quick config highlighting the frame-relay portion for on of the e-scenarios.  I am connecting two 2500 routers via a DTE/DCE serial cable.  The issue that I am running into is that the line comes up for a few seconds and then the serial interface goes down on the DTE side.  When I issue a show frame-relay pvc command, the DLCI shows as being deleted.  Am I missing something?  I was able to get it to work for a few minutes the other day but not since then.  Thanks, Jamie
