Oracle Solaris introduced two new features on Solaris 11 which different from Oracle Solaris 10. There are some changes for “dladm” command and also a new command “ipadm” which will help us to configure network interfaces. Instead of “ifconfig” changes made by “dladm” and also “ipadm” are persistend across reboot.
“dladm” helps administrator two perform data-link (layer 2) operation like configure physical links, Vlan,aggregations etc. And also changing link layer properties.
Another point that introduced on Solaris 11 link name are not physical name like e100g0,bge0 etc. It means that data-link name are not same as physical link name . As I showed below.
# dladm show-phys LINK MEDIA STATE SPEED DUPLEX DEVICE net0 Ethernet up 1000 full e1000g0 net1 Ethernet up 1000 full e1000g1 net2 Ethernet up 1000 full e1000g2
As you see from command output Link name are “net0-1-2” and also physical-link name are “e1000g0-1-2”. Remember that on Solaris 10 data-link and physical-link name are same as. This will help us to give spesific names to data-link . You should change “net*” as you want.
# dladm show-phys LINK MEDIA STATE SPEED DUPLEX DEVICE net0 Ethernet up 100Mb full e1000g0 net1 Ethernet up 100Mb full nge0 # ipadm delete-ip net0 # dladm rename-link net0 oldnet0 # dladm rename-link net1 net0 # ipadm create-ip net0 # ipadm create-addr -a 192.168.91.140/24 net0 ipadm: net0/v4 # dladm show-phys LINK MEDIA STATE SPEED DUPLEX DEVICE oldnet0 Ethernet up 1000 full e1000g0 net0 Ethernet up 1000 full nge0
Also you can create network profile and apply them with “netadm” and “netcfg” command. Her is an simple example of create network profile with “netcfg” command. It names NCP on Oracle Solaris 11.

There are two modes for Oracle Solaris 11 Manual an Automatic Networking modes which named “Automatic” and “DefaultFixed”. Automatic network profiles use DHCP to obtain basic network configuration like IP addres netmask and gateway. DefaultFixed mode needs to configure network interface manually with “dladm” and ” ipadm” commands. If you are an administrator like me to take all control of system you should disable Automatic networking options . Link aggregations operations needs to DefaultFixed mode. So If you ‘ll create aggregations you need to change default Automatic mode to DefaultFixed.

A simple example about how to create static ip with ipadm command manually.

Last but not least important changes on Solaris 11 is SMF.Name service configuration is stored on SMF instead of /etc file. This configruation changes make a big advantages to manage system changes on patching and other works.
