you'll need to sudo apt-get install vlan first... save the mod in case of reboot...
see http://blog.ipexpert.com/2011/02/28/gns3-and-physical-switches-breakout-switch/#more-6136
word of caution, you can try to screw around with creating a root account... don't...
i made a text file to quickly build the nix interfaces...
you can use vconfig to make the vlans, but you'll still have to add the ip's to the nic (waste of time)... this does it in one step...

then sudo service networking restart to kick them off...

note dot1q for port 11 which is from the nix box to f1/0/1 of the breakout...
you'll need svi's on your connecting mls for each vlan, as well as the vlans... don't forget to make the vlans first...

on the breakout you need the l2protocol-tunnel statements for each l2 proto, cdp, stp and (arghhhh) vtp (cough) as well as sw acc vlan x for the corresponding supported vlan...
don't bother with the routing protocol on the gns routers until you've proven cdp, and basic l3 connectivity first...
