I have been testing a DLSW ethernet session between a mainframe IBM and a Tandem. I noticed that It gets connected after a long time, I found in my dlsw reachability table that I have the remote mac-address in the Local and remote reachability. I think it is the problem, sometimes when I clear the reachability table it gets connected but not always.
I don't understand why I saw the mac-address in local, I have some services to the same ibm host with serial ports (SDLC).
Is there a way to force the remote mac-address in the remote reachability?
