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.
