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.
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.
