I have been trying out some configurations here and are struggeling a 
bit - it seems like the M series does not support to act as a DHCP 
server. Is there any clever way to get a dhcp server on each 
interface/vlan to tell the client its correct ip address?

I am thinking a stupid solution like using a *nix server to bind up all 
the vlans and giving away dhcp this way, but there has to be better ways 
to go.

What is the list price of a ERX-310 ? Seems like this is a mutch better 
bet for this type of setup really...
