Ethernet Support Guide for HP-UX 11i v3

Other possible causes of a fault condition could be:
• A defective cable
• A cable not connected to an active hub or switch
• A defective card
4.3 Diagnostic flowcharts
Table 15 summarizes the types of network tests recommended in the diagnostic flowcharts.
Table 15 Diagnostic flowcharts
PurposeType of testChart
Checks that hardware, cables, and connectors between your system and
card are operational.
Cable and LED test1
Checks communication between link levels on source and target host using
nwmgr.
Link-level test2
Groups the ARP and ping tests at the network level (for the details of these
tests, see Figure 4 and Figure 5).
Network-level tests3
Verifies that an entry exists for the remote host in your system's ARP cache.ARP test4
Checks communication between network layers on the source and target
host.
ping test5
Checks communication between transport layers on source and target host
using telnet and ftp sessions.
Transport-level test6
Checks general network connections through a gateway.Bridge/gateway loopback

Verifies configuration of network interface on a host using ioscan, nwmgr,
netfmt, nwmgr --diag, and ifconfig.
