sdlc address state change

What causes sdlc address state to change? We are attempting to attach a 3174 look alike controller to a cisco 1721 using a wic-1t. interface. The show interface commands shows Serial1 is up, line protocol is up and that ; DCD=up DSR=up DTR=up RTS=up CTS=up. The problem is the sdlc address state shows sdlc addr DC state is DISCONNECT.

The sdlc test command does not send a snrm and debug sdlc show no output at all.

I have tried a different router with a different wic 1t and same results.

I have tried 3 different interface cables.

I have gotten it to work successfully with the wic 2t card.

Re: sdlc address state change

Whenever I get this message I call the guys managing the AS400 and tell them to reset the controller. This solves the problem everytime.

If you use STUN, the you should see something like this. Your SDLC local ack will say disconnected though.

This peer: 10.201.0.6

Re: sdlc address state change

thanks for the reply! I am also the vtam sys pgmr. the router is not yet trying to get to vtam. I am trying to verify the router interface can 'talk' to controller with the sdlc test command using the cable.
