Assign IP for each me0 interface on switch in a VC

Hi all!

Newbie here, I've been trying to setup an OOB network for our EX4300 switches in a VC. I would like to individually assign IP addresses to the me0.0 interface on each switch (master, backup, linecards). We want to go this route instead of VME to monitor by ping.

In the config we are using groups -> member# -> interfaces -> me0 -> unit 0 -> family inet -> address -> x.x.x.x/21

I've read the article here about troubleshooting and assigning linecards individual IP addresses. My question, is there no other way to assign an IP address to these individual switches me0.0 interface besides going in shell and using ifconfig? 

Thanks for any help!
