RFC1490 Format
An RFC1490 format used for SNA traffic is configured in the frame relay LLC2
Interface/Bridge Port record. The options, in order of lowest overhead to highest
overhead, are:
Native LL C2 (als o known as BNN, or Bo undary N e twork No de). Whe n this
format is used, no MAC addresses are transmitted across the frame relay link.
802.5 SR B (sourc e route b ri dge) (al so known as BAN, or Boundar y Acces s
Node. (SmartSwitch 1800 devices support BAN type 1). This format is gen-
erally used for 3174 gateways and AS/400s, because they need to see a MAC
address).
802.3 TB (tran sparent bridg e), use d when ta lking t o router s that cannot d o BAN
or BNN.
Subscriber IDs
Subscriber IDs are only used locally within each SmartSwitch 1800 to link records
(e.g. SDLC PU record to LLC host record), unless the device is running X.25, SDLC/
LLC2 p ri m ary (th e SmartS witch 18 00 would be SDLC sec ondary t o the FEP) , or
logical ports (i.e., QLLC), in which case the subscriber IDs correlate to the static
routes defined in the subscriber routing tables.
Netview Service Point
NVSP is supported only via LLC2 connections. The local and remote subscriber
addresses always point to the LLC2 Originated Host record, and are the opposite of
the respective local and remote subscriber addresses configured there.
Producing a Configuration Report
A configuration report contains this information:
Software version number
Passwords
Boot time
Various database parameter values
Line status for each port
To create a configuration report, press [A] at the Reports Menu (or [F], [A] from t he
Main Me nu). The report i s create d a nd saved to the node 's hard disk unde r the nam e
REPORT.TXT.
You cannot generate a configuration report while a file transfer is in
progres s.
