What isn't working.
Do the machines on the lab vlan not get an IP address?
What device is routing from lab vlan to the vlan where dhcp server is?

Subject: Setup separate lab VLAN

Hey all,

I'm truly stuck, hopefully I can find some assistance here.

I have a client which is a school that is running out of IP addresses.  Their 
subnet is 192.168.1.x/24  I would like to segment off their lab, which is 
around 50 PC's right there (in addition to all the youtube/facebook users) on 
it's own VLAN using subnet 192.168.2.x/24

I'm currently using 4 Extreme x460's - 1 of which is dedicated only to lab 
machines.  I've set up another DHCP scope for the 192.168.2.x network.  I 
created a VLAN on the switch and did the following commands:

Create vlan Lab
Configure vlan lab ipaddress 192.168.2.10/24
Configure vlan lab add ports 1:1-1:48
Enable bootprelay vlan lab
Configure bootprelay add <ip of DHCP server>
Configure bootprelay dhcp-agent information option
Configure bootprelay dhcp-agent information check
Enable ipforwarding vlan Lab

I activated the scope, but it doesn't work.  Is there a manual scope option 
that needs to be entered?

Thanks,

Jay
