Chris, If you are not using Anynet, then the routers are determining how to reach the controllers. They will be either bridging the SNA traffic or using Datalink Switching. The AS400 just thinks that it is communicating to the controller on the local LAN. Basically, the routers will listen to the MAC addresses and if they are not on the local network, they will ask their neighbours if they can reach them - if they can, the packets will be forwarded on. With DLSw, the routers will spoof the local acknowledgments to prevent timeouts from occuring. If you are using bridging, the timers on the controller description may need to be extended to prevent timeouts. -- Mike Buglass Technical Consultant DCS eIntegration Nottingham, England ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
