Using TN3270

The TN3270 application allows users with non- TN3270 servers to monitor statistics from TN3270 servers. For each instance of TN3270 Server running in the specified router, TN3270 Monitor establishes a TCP/IP connection to the first TN3270 Server-configured physical unit (using the IP address) and begins polling for the tn3270sGlobalTable and tn3270sStatsTable MIB variables. The TCP/IP connection allows the router to send TN3270 events to the TN3270 Monitor program. You can then view the events in filtered views.
