I am having some problems with my configs for my routers, its a problem that has only recently occured and appears to be ios independant, although I can't guarantee it.
I can put the config in the router and all will work fine however if I reboot the router fails to connect. A show isdn stat says layer 2 is not activated. If I unplug and replug the isdn it works again. This has happened at at least 4 sites so the isdn supply is unlikely to be the issue, as is the actual router as I have tried 6 so far that show this problem. It usually occurs with the original IOS so I try upgrading to c800-y6-mw.122-13a.bin but this makes no difference.
I get the same issue if I use faststep as well.
I have included the config and a copy of what happens when I unplug and replug the isdn at the bottom.
OK, I have another one that might apply. You are doing something with the clock, probably to allow connections only on specified times. After a soft reset, the clock settings are gone and you start again at 0:00:00. In your config the ISDN is blocked during this time, it will take until 05:30 (or 5,5 hours uptime) before the clock reaches a valid time for ISDN to activate. Did you check what happens when you change this?
To make this work, you would need to configure ntp to set the clock. The ntp source should not be on the remote side of the ISDN link, otherwise you will have long uptimes.
Hi everyone, I would like to thank you in advance for any help you can provide a newcomer like myself!
