How to Identify Logical and Physical Network Interface Names

Use this procedure to display information about MAC addresses and network interfaces, including their logical and physical names (MAC addresses).

  1. In the Install Type menu, select Option (6) Single User Shell, and press Enter.

    Note - Alternatively, you can run these commands from a command shell.

    If a message appears about mounting an OS instance, select q. You should not mount any OS instance.

    The message "Starting Shell" appears. See the following figure.

  2. At the command prompt (#), type the following command to plumb all network interfaces.
    # ifconfig -a plumb

    Note - The plumb process might take some time.

  3. At the command prompt, type the following command.
    # ifconfig -a

    The output of Solaris named interfaces and MAC addresses appears. For example:

    image:Output of Solaris named interfaces

    In the sample output:

    • The el000g# entry in the first column refers to the Solaris logical named interface. This first column in the output identifies the logical names assigned by Solaris to the network interfaces.

    • The ether #:#:#:#:#:# entry in the second column (third row) refers to the physical MAC address name of the network port.

      For example:

      The physical MAC address for the Solaris named network interface is e1000g0 is 0:14:4f:c:a1:ee.

  4. Save this information to a file, or write it down.
  5. When you are done, to start the system configuration script, type sys-unconfig(1M) at the command line.

    This command restores the system configuration to the factory defaults.


    Caution - The sys-unconfig(1M) command halts the system and restores the factory settings. Do not run this command unless you are ready to reconfigure your system.

    For example:

    # sys-unconfig
    This program will unconfigure your system.  It will cause it
    to revert to a "blank" system - it will not have a name or know 
    about other systems or networks.
    This program will also halt the system.
    Do you want to continue (y/n) ?

    The system reboots and the configuration script starts.
