Interpreting ndstat(ADM) output

Configuring Network Connections
Chapter 1, Configuring network connections

Use the ndstat(ADM) command to examine the status of the network interface. Here is an example of ndstat output:

Device MAC address in use Factory MAC Address ------ ------------------ ------------------- /dev/net0 00:00:c0:ec:d5:4c 00:00:c0:ec:d5:4c

Multicast address table ------------------------ 01:00:5e:00:00:01

FRAMES Unicast Multicast Broadcast Error Octets Queue Length ---------- --------- --------- ------ ----------- ------------ In: 33254 0 16133 7 4880475 0 Out: 24785 3 16 9 3029828 0

A certain number of errors is normal. It is considered normal if the total number of errors listed in the Error column is less than 1% of the total number of FRAMES in and out.

If ``In'' and ``Out'' are both zero:
You cannot reach a remote host and your network interface is probably using a different interrupt vector than its device driver.
If ``In'' is non-zero but ``Out'' equals errors ``Out'':
The I/O base address for the network adapter may be incorrect.
If ``In'' is zero and ``Out'' equals errors ``Out'':
The network cable may have a faulty connection.

In a TCP/IP environment, the netstat(TC) command (particularly the -i, -m, and -s options) is also useful for identifying physical network problems. For more information, see ``Troubleshooting TCP/IP'' in the Networking Guide.

If you are not using TCP/IP, see crash(ADM).
