Configuring Async.-Interfaces

[gerbers]

Hello everybody,

i got a HWIC-8A/S-232 interface inserted in a ISR3845. On the according interfaces i got following configurations:

interface Serial0/0/0

physical-layer async

ip unnumbered Loopback0

encapsulation ppp

async mode interactive

peer default ip address pool default

ppp authentication chap

!

line 0/0/0

modem InOut

transport input all

flowcontrol softwar

Situation:

I get access to the router even the interface state of s0/0/0 is down/down.

Question:

How can i get access if the interface where the server is connected is in state down/down ?

Thanks for your help

regards

stephan

Are you sure there is no other path available?

If so, please post the output from "deb ppp neg" that contains the routers' output when a connection with the server is established and disconnected.

I'm sure there can't be another path available because there is no other connection between the server and the ISR.

I'll attache the debug output as soon as i get remote access to the system.
