Solaris interfaces – create assign delete

Working with interfaces in Solaris is pretty much the same as in Linux – you’ve got ifconfig, netstat,route. It looks in outputs a bit different but if you’re used to the *BSD way of things you’ll find yourself at home. So the most basic thing follows – bring interface up, assign ipv4 address, save the change to survive reboot.
Plumb. First step sounds a bit strange – plumbing, but is actually very simple (no need to call for Mario) . You just plumb the interface (I talk about Ethernet-type interfaces) to the IP stack.
- Interface before plumbing :

Even an unplumbed interface can be seen with:

- Now plumbing:

Assing IP and bring it up. This one is well known.

Make this change permanent
So far so good. But if you do restart to the machine now it will lose its interface settings. To save them you create a text file named /etc/hostname.<interface name> In my case it will be /etc/hostname.e1000g2 , this alone would plumb interface on start, and now put the IP address inside it in the form ’192.2.2.3/24′ . That is it.

To see if interface is up or down as a device and its duplex/speed parameters:

Create/delete logical interface In Cisco world you would call it assigning secondary ip to the interface.

Created new logical interface e1000g1:1

Remove logical interface:
