Since no one has answered this in 2 days, I'm going to go ahead and give more general advice. I know nothing about iperf, 802.1Q, MPLS, VRF etc...

What are you actually having trouble with? What is happening that you don't expect to happen? Are you asking for help solving a particular problem or are you asking for strategic advice for the best way to performance test a MPLS switch (whatever that is...)?

Good luck

P.S. Okay, I looked up iperf & MPLS and I think you're asking "how do I make 20 instances of iperf work at the same time?" Since you're attaching to these 20 different virtual interfaces, you'd just need to tell the server end which ip to bind to. EG iptraf -s -B 192.168.0.1 & iptraf -s -B 192.168.1.1, etc....

tgt-setup-lun(8)					      System Manager's Manual						  tgt-setup-lun(8)

NAME

       tgt-setup-lun - creates a target, adds a device to the target and defines initiators that can connect to the target

SYNOPSIS

       tgt-setup-lun -d device -n target_name [initiator_IP1 initiator_IP2 ...] [-h]

DESCRIPTION

       Starts tgtd if necessary and creates a target according to the supplied target_name. The format of the target name is as follows:
       iqn.2001-04.com.<hostname>-<target_name> The target name must be unique.

       The  script then adds the requested device to the target. If specific IP addresses are defined, it adds them to the list of allowed initia-
       tors for that target. If no IP addresses is defined, it defines that the target accepts any initiator.

EXAMPLES

       Create a target that uses /dev/sdb1 and allows connections only from 192.168.10.81:
       tgt-setup-lun -d /dev/sdb1 -n my_target 192.168.10.81

       Create a target that uses /dev/sdb1 and allows connections only from 192.168.10.81 and 192.168.10.82:
       tgt-setup-lun -d /dev/sdb1 -n my_target 192.168.10.81 192.168.10.82

       Create a target that uses /dev/sdb1 and allows connections from any initiator:
       tgt-setup-lun -d /dev/sdb1 -n my_target

       Display help:
       tgt-setup-lun -h
