I'm working on configuring dialout with a Cisco 2511 router and external modems. The end point is a dial-in server, which will create a ppp connection. I use this guide as a reference but it only work with async1 port, when I switch to async2 and ping the server, the router doesn't dial the server.

Config: client computer==(ethernet)router==(async port)modems----pstn----modem==dial-in server(s)

Can someone help me out of this? A detail answer or document will help me much since I'm new with this things.

Update: the result of sho run

Which server did you ping? You need to ping 192.184.9.X to use your async2.

Configuration looks fine, same config on async1 an async 2 no reason asyn2 not working.

Do a debug ppp and debug dialer and let us see.

  • Hi, I ping the addresses in the dialer profiles (after change the async line), I can't provide an exact log file right now, but I remember the `debug modem` stop at `asserting dtr...`, It seem something is wrong with the line, my friend suggest maybe it's the modemcap. Change it to `type hayes` make the call happens, but I can't ping the server. I'm still working it out! – Tiana987642 Oct 02 '13 at 15:27
  • This is better as a comment. Once you have enough reputation you will be able to comment on posts – Dave M Oct 02 '13 at 15:36
  • Oh! If it stops at asserting DTR (raising the "data terminal ready" flag to the modem), it sounds like perhaps negotiation is failing, or the modem interface card is faulty. Or, indeed, the modem is just confused, since you say `type hayes` makes it get past that point. – Falcon Momot Oct 03 '13 at 09:10
  • Thank all, finally, it works! I can't tell the exact reason, maybe the problem is the router itself. It just locked me out yesterday even I entered the correct password(a cold reboot fixed it). The "magic word" is a mistyped command, then it starts `Translating "xxxx"...domain server` and woo hoo, all the modems start to dial. Really weird! – Tiana987642 Oct 05 '13 at 08:49
