Does the ER8411 support subinterface?  My L3 switch doesn't support dhcp server only relay, the L2 switch I have in the network does support dhcp server but when there is a load it just locks up the daemon.

I was wondering if the ER8411 can become the dhcp server, but it would have to make the SFP+ WAN/LAN port a subinterface to pass L2 requests.

Remember in my topology my L3 is routing to the ER8411.
