Network configuration in SMF

When tools like ipadm were introduced to Solaris, the first question in most presentations in that time about this topic the location where the data is stored. I showed it to customers, however with the strict suggestion “Don’t dare to edit this file, it may change without further notice”. Well, the location where this data is stored has changed with Solaris 11.4.

When you look into the SMF service, you will see a number of properties used to persist the networking config of your system.

root@batou:/# ipadm

lo0               loopback   ok           --         --
   lo0/v4         static     ok           --         127.0.0.1/8

   net0/v4        dhcp       ok           --         192.168.30.204/24

This makes it much easier to deploy much more complex network configurations via AI for example.
