Hi, We have tow location ,they use DLSW to comunicate. In our office we have a AS400 connected with a Cisco 2501 router by SDLC, in other site they have a AS400 and a Cisco 7500 connected through ethernet. My question is when I config SDLC interface , how to identify the vmac and partner mac address to correspond to our host or remote host mac address? Is there anything else should be pay atthention to ?
