I am configuring 2 X 2910al's with a 4GB trunk between them and 11 VLans. Everything is working as it should except DHCP. Workstations on the management/primary vlan pick up their DHCP addresses just fine but all other vlans fail. How do I configure a seperate gateway IP address (I'm assuming that the helper IP is the vlan's gateway) for each of the other vlans. Everytime I try and add an IP for a vlan (using the gui) other than the primary, I lose my connection to the switch and I find that the primary IP has been changed.
