Vanity names for network interfaces

Wednesday, January 30. 2008

Sebastien posted a walk through a really nice feature that found it´s way to the Opensolaris build 83: vanity names for network interfaces.

Now you can give any name you want to a network interface. For example: You have four e1000g interfaces in your system. Without this feature they would be named e1000g0 to e1000g4 by Solaris. Now you name them eth0 to eth1 with some simple commands:

dladm rename-link e1000g0 eth2

But why should you use the cryptic linux naming scheme? We can do better than that!

   dladm rename-link e1000g0 internet0

   dladm rename-link e1000g1 dmz0

   dladm rename-link e1000g2 private0

You don´t see the name everywhere ... AFAIK you don´t see it in the ifconfig output ...

the name is visible also in ifconfig (and other tools):
# ip link set dev eth0 name internet0
# ifconfig internet0
internet0 Link encap:Ethernet HWaddr 00:15:F2:3C:6B:A1

If that's supposed to be an example for Linux you probably mean nameif (which renames interfaces based on the mac address).
