Create a Virtual Interface in Solaris

Posted September 4, 2003 by Quinn McHenry in Solaris networking

Virtual interfaces allow a single ethernet interface to listen on additional IP addresses.


Given an ethernet interface hme0 (use ifconfig -a to identify the names of your interfaces), you can create a subinterface called hme0:1 with the following command:

ifconfig hme0:1 plumb

You can set the IP address of the interface to 192.168.1.15 and turn on the interface with the following command:

ifconfig hme0:1 192.168.1.15 up

Unless you do some additional nonstandard things in your network, all of the subinterfaces on a physical interface need to be in the same subnet.

To make the virtual interface persist following a reboot, you can add the ip address or hostame from /etc/hosts in the file /etc/hostname.hme0:1
