The PPA number is the unique number assigned to each physical device. As shown in this
lanscan display, a single hardware device may have multiple namePPA identifiers, where
the name indicates the encapsulation method, and multiple encapsulation methods could be
supported by the device. In this example, each device supports Ethernet encapsulation, as
designated by the name lan, and Subnetwork Access Protocol (SNAP) encapsulation,
designated by snap.
ioscan command: device description
The ioscan command displays the hardware path and device description of all reportable
hardware found on the system. In the following abbreviated example, the lan8 interface
(which you can identify by the hardware path 0/4/0/0/0/0 that was revealed in the
preceding lanscan example) is shown to be for an NC552m dual-port 10 Gigabit Ethernet
adapter.

• To verify link-level connectivity with a remote system, enter, where destination_MAC is the
remote system's MAC address and ppa is the PPA number of the remote system device:
nwmgr --diag -A dest=destination_MAC -c lanppa
NOTE: when you use nwmgr --diag to check connectivity, ensure that the remote system
is on the same subnet and is an HP-UX-based system.
• To verify IP-level connectivity with a remote system, enter:
ping Remote_IP_Address
and
netstat -in
When you use netstat -in, the displayed values Ipkts and Opkts should be
incrementing.
• Installation is complete when you have successfully run nwmgr --diag -A
dest=destination_MAC-c lanppa, ping, and netstat.
To set up communication between the local IP network and remote IP networks, configure a
gateway using the route option under the SMH Network Services Configuration screen, or
use the route command to put the new route into effect on the system as follows:
/usr/sbin/route add default router_ip_address 1
• Optionally, if you want to verify that the system recognizes the LAN driver for each installed
card, enter:
