Introduction to Database Configuration 3-9RFC1490 FormatAn RFC1490 format used for SNA traffic is configured in the frame relay LLC2Interface/Bridge Port record. The options, in order of lowest overhead to highestoverhead, are:l Native LLC2 (also known as BNN, or Boundary Network Node). When thisformat is used, no MAC addresses are transmitted across the frame relay link.l 802.5 SRB (source route bridge) (also known as BAN, or Boundary AccessNode. (FRM devices support BAN type 1). This format is generally used for3174 gateways and AS/400s, because they need to see a MAC address).l 802.3 TB (transparent bridge), used when talking to routers that cannot do BANor BNN.Subscriber IDsSubscriber IDs are only used locally within each FRM to link records (e.g. SDLC PUrecord to LLC host record), unless the device is running X.25, SDLC/LLC2 primary(the FRM would be SDLC secondary to the FEP), or logical ports (i.e., QLLC), inwhich case the subscriber IDs correlate to the static routes defined in the subscriberrouting tables.Producing a Configuration ReportA configuration report contains this information:l Software version numberl Passwordsl Boot timel Various database parameter valuesl Line status for each portTo create a configuration report, press [A] at the Reports Menu (or [F], [A] from theMain Menu). The report is created and saved to the node's hard disk under the nameREPORT.TXT.You cannot generate a configuration report while a file transfer is inprogress.To display the configuration report, press [B] at the Reports Menu (or [F] , [B] from theMain Menu).
