Display information about a network interface controller
 |
If you aren't root, specify the full path: /usr/sbin/nicinfo. |
nicinfo [-r] [device...]
- -r
- The specified devices are relative to /dev/io-net/.
- device
- The device to display information about. The default is
/dev/io-net/en0.
This utility displays information about the given network interface connection,
or /dev/io-net/en0 if none is specified.
The information includes the number of packets transmitted and received,
collisions, and other errors.
 |
The output from nicinfo depends on what the driver supports;
not all fields are included for all drivers.
However, the output always includes information about the bytes and
packets that were transmitted and received. |
