Question : 3com not relaying DHCP across vlans

Hi everyone,
I am having a problem with my 3com 5500G-EI relaying dhcp. The dhcp requests needing relayed are coming into Port 1 on the 3com switch. The dhcp requests r for clients on vlan99 and vlan100. I've attached the config. Help! What am I doing wrong?

Answer : 3com not relaying DHCP across vlans

I solved the issue! Replaced it with a Cisco 3750 stack. I appreciate the post above, but I'd gone all through the manuals and tried it all...just wouldn't work. When I replaced that switch, the problem went away. Went through code updates, global or vlan based dhcp relay. Forwarding the request and actually relaying the request. Just a no go. Anyway. this question can be closed. Thanks!
