Troubleshooting 10/100Base-TX/9000

Below is a summary of the types of network tests in the diagnostic
flowcharts. Follow the flowcharts in sequence beginning with flowchart 1.
Continue sequentially through flowcharts 2, 3, 4, 5, 6, 7, 8, and 9,
referring back to flowchart 1 (ping), as indicated at the end of each
flowchart, until you have corrected the problem.

Network Level Loopback Test: Checks roundtrip communication
between Network Layers on the source and target host using the
ping(1M) command.

10/100Base-TX Connections/LED Test: Checks that all the hardware
connections between your system and the 10/100Base-TX network are
connected and operational.

Configuration Test: Verifies the configuration of the network interface
on a host using the lanscan(1M), netfmt -vf, lanadmin(1M), and
ifconfig(1M) commands.

Network Level Loopback Test (cont): Checks arp entries using the
arp(1M) command.

Link Level Loopback Test: Checks roundtrip communication between
Link Levels on the source and target host using the linkloop(1M)
diagnostic.
