vifptarget command not found

Hello, there

I installed vMA to use troubleshooting command. The version of vMA is down below

Linux vma1 2.6.18-128.1.1.el5 #1 SMP Mon Jan 26 13:58:24 EST 2009 x86_64 x86_64 x86_64 GNU/Linux

I tried to use some commands but I couldn't find vifptarget command.

VMware version is ESXi 5.0

what should I do?

and what's the difference between vifptarget and vifpinit command.
