Hi,


I'm a newbie in this area. I'm trying to connect a OS/2 SNA server to a S/390 mainframe using DLSW.


The connection will look like this:


OS/2 SNA Server ---> Cisco 2500 w/DLSW ---> IP Backbone --- > Cisco 7513 w/CIP ---> S/390.


The status is as follows:


agencia#show dlsw reachability

  • Cisco Employee,

It doesn't appear in the debug that the OS/2 device is truly trying to establish the connection to the mainframe. We do see some broadcast NetBIOS traffic on sap F0 but nothing resembling a SNA packet on SAP 04 or 08 etc... We need a SNA test poll to the MF's MAC address to initiate the conversation.
