Chapter 6 Diagnostics 6-29
6.10.3 Using watch-net and watch-net-all
Commands to Check the Network Connections
The watch-net diagnostics test monitors Ethernet packets on the primary network
interface. The watch-net-all diagnostics test monitors Ethernet packets on the
primary network interface and on any additional network interfaces connected to
the system board. Good packets received by the system are indicated by a period (.).
Errors such as the framing error and the cyclic redundancy check (CRC) error are
indicated with an X and an associated error description.
Start the watch-net diagnostic test by typing the watch-net command at the ok
prompt. For the watch-net-all diagnostic test, type watch-net-all at the ok
prompt.
For additional information about diagnostic tests for the OpenBoot PROM see:
