HP-UX System Administrator's Guide: Configuration Management HP-UX 11i v3 (B3921-90017, September 2010)
If your system does not need to access another system on a different network, you can
assign the local system’s IP address as the ROUTE_GATEWAY, because it will be routing
all network traffic directly to other local area systems. If the local system will be
communicating with systems outside the local network, the ROUTE_GATEWAY must be
the IP address of the gateway router. The system maintains a dynamic routing table
in memory. This routing table is dynamic information on how to route to a specific
system or network. You can add and delete routes in this table by using the route
command. You can force a specific path to a destination if there is more than one way
to get there. For details, please see the route(1M) manpage.
To verify the configuration, use the netstat command to display the current routing
table.

Setting Speed and Duplex Mode of the LAN Card and Link Partner (Switch or Router)
Gigabit Ethernet Base-T connections on those cards operate at 10 or 100 megabit/s in
either full- or half-duplex modes and at 1000 megabit/s only in full-duplex mode.
When the LAN autonegotiates, it achieves the highest performance if the link partner
(switch or router) is also set to either autonegotiation or 1000FD. The following table
shows the resulting speed depending on the settings of the ports on the card and on
your router or switch.
