HP-UX System Administrator's Guide: Configuration Management

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.

Ensuring Card and Link Partner Speed and Duplex Settings
A lot of duplex mismatch issues can show up as other problems. The following nwmgr
results can tell whether the card and link partner are operating as you need.
1. Obtain the PPA number of each LAN link you are testing with nwmgr.
