Multiple DHCP scopes on TZ215 with Cisco SGE2010 managing the Vlans

I have a Cisco SGE2010 connected to a Sonicwall TZ215. There are 3 Vlans being managed by the switch - 10.0.1.0/24, (Vlan 1) 10.0.10.0/24 (Vlan 10) and 10.0.20.0/24 (Vlan 20).
On the Sonicwall router - Interface X0 is main Lan subnet 10.0.0.0/24. Interface X5 is connected to the Cisco switch with an IP of 192.168.100.1/30 and the Cisco has it's main IP address set at 192.168.100.2
All Vlans and the Main Lan are communicating with each other and all subnets can get to the Internet. My problem is I need the Sonicwall to provide DHCP addresses to each Vlan subnet.
There is a post on this site that did this, but the specific configuration steps on both the router and the switch are not given. Can someone help me with this?

Thanks in advance

If I remember right, the tz series doesn't understand vlan packet tags. You have to get to the NSA for that.
So the trick is connecting one port for each vlan from the Cisco to the sonicwall. Each port is a different x interface on the sonicwall and the Cisco is set to only allow a single vlan on each of those ports. You can then assign a dhcp scope to each x interface

Ahhh, I just saw that in the 5.8 release notes. Interesting. Glad you got it working.

I new what I needed to do, but did not know how to get into the the command line interface for the cisco small business line of switches as it is not documented. Basically what you have to do is log on to the console and when you are at the menu, you press control z and key in lcli (light weight command line interface), then you log on again and are now in cisco's regular command line interface shell. You don't have all of the commands available but you can do most of the configuration you need that the web GUI will not give you access to.
