Need help to configure isdn and analog dial in

[epag]

Hello,

I've a problem with an dial in on a 3640 with a NM-4B-S/T= and a NM-30DM= .

I can dial in from a PC and it works fine, but when 3 or 4 connections are established sometimes no traffic come back and I've to reconnect and it is then working.

Can someone give me a sample config for it ?

please help

Hello Carsten,

can you post your current configuration ? There are numerous bugs related to the NMs - which IOS version are you running ?

Can you please capture the debugs of a connection that does not pass traffic:

deb isdn q931/ deb modem / deb modem csm / deb ppp nego.

1) Do all the dial up connections stop passing traffic or just the latest connection?

2)After the call is connected: sh ip route & try pinging the host (try deb ip packet detailed with an access list...very inprotant to have access list)

Thanks, Mak.

Do all the calls stop passing IP traffic when the problem occurs? If not, see if you encounter the problem only if you connect to a certain digital modem.

Does it help if you enable "ip cef"?
