Bank ATM machine problems

jbouwkamp · ‎01-26-2003

I have been working on moving a Bank's ATM machine over from an old 2520 router to a newer 3640 router. The ATM machine works using BSTUN with a loopback address. I duplicated the configuration on the 2520 EXACTLY onto the 3640 but could not get the ATM machine talking with the new router, as soon as I put the old router back in place the ATM machine came up. Is there something easy I am missing when trying to make this switch? I can post the running configs of both if needed but it would require alot of editing (It is a bank..heh).... thanks in advance!

hmm, sounds familiar....

Sometimes, changing the router and copying the exact config doesn't work,

specially if the router was changed from one platform to another.

I assume you are using the same cable to connect to the ATM machine.

This be could be a software issue and it would be better if you could review

the Release Notes for the IOS version of your 3640.

Some of the default 3640 configurations might have an effect.

If the serial interface is a dce do not forget to set the clock

jbouwkamp · ‎01-27-2003

The original 2520 router had the ATM plugged in on Serial 1 with no clock rate settings, the new 3640 router has the ATM plugged in to serial 1/0 with no clock rate settings. So does that sound like the clock rate is a correct issue? (I would test it but its a two hour drive to the site and no remote access...) thanks! I had the baud rate set to 9600 so should clock rate be the same? When I do a show bstun events it shows that the remote router is sending signals but the local ATM is showing no packets, would no clock rate setting cause this? thanks for the help!!

you only need to set the clock if your serial interface is acting as the DCE. do a sh controllers and see if a dce cable is attached. If the line goes up it is not a clocking issue.

Can you paste configs from the 2520 & 3640

This is probably to simple, but is the new serial interface shutdown? The problem may be as simple as typeing no shutdown on the interface in question.

jbouwkamp · ‎01-27-2003

no shutdown has been entered :)

If it was working with the 2520 router with no clock settings,then it shouldn't be the culprit. It would be helpful if you can post the IOS versions of the routers,

an extract of the config, and some debugs you have captured.

Can you paste in the output of sh int s1/0 and sh bstun

jbouwkamp · ‎01-28-2003

It might be Monday before I can do that, I am 2 hours away from site and don't want to make the drive till I have a solution and the person that is on site that could get the configs for me is away on training this week. I will post them Monday for sure and I appreciate all the help!
