Hi,all,

I Have a Cisco 3640 router with IOS version 12.0(7)T,I config it with

fram-relay and one-step tunnel ppp over x.25, in the above IOS version,

It can work correctly but always reload,So I upgrade the IOS version to

12.2,of cause I increase the flash and DRAM,but the remote user can't communication to the Center well,when the remote user increae the

traffic a little,they found they lost the communication to the center,I don't

know why? I changed several 12.2 IOS version ,all is the same,I change

it back to 12.0 or 12.1,It's Ok,But always Reload,Is it a IOS BUG? I don't

know how to solve it,Plese help me! THANKS!

Re: tunneling ppp over x.25

Obviously you have 2 issues; the crash, which would require the output from "sh stack" to go further, and the connectivity issue with 12.2. For the connectivity issues, I would try the latest 12.2 mainline code, and check the output of "sh int" , "sh translate", and "sh buff" while you have a connection established. You want to look for any errors, dropped packets, or other issues that may point to a problem.
