Title: How the Terms Networks, Ports, and Paths Are Used for IBs and BRs
Date: 6/22/90

For IB Version 11000 and earlier releases, "networks" used to mean a
logical connection.  Now, "port" is used instead.  "Path" means a physical
connection such as leased lines.

Port 1 and path 1 are for the local Ethernet segment; other port and path
numbers are for other segments.  For example, if there are four leased
phone lines between sites A and B, then you may assign paths 2, 3, 4, and
5 to port 2.

The following information relates to changes that have been made in
syntax and documentation in SW/20-IB Version 2.x, 3.x and SW/20-BR Version
1.x:

*  The names of the NetWork and NetworkDefault commands have been
changed to PorT and POrtDefault (IB-2.x) and SetD -port (IB-3.x and
BR-1.x), respectively.

*  You can no longer assign 0 to a path.  If you are upgrading from
SW/20-IB Version 11000 or earlier to 2.x, use the PAthDefault and
POrtDefault commands to renumber ports and paths.

*  If you are upgrading to IB-3.x or BR-1.x, use the SetD command.  If
you do not know the correct syntax, use the new Menu command and select
Port and Path sub-menus.  Port 0 means the system itself; it is used
for network management purposes such as remote or Telnet connections.
