Brocade Switch: DHCP and the 'ip helper-address' Command

Dont forget.  When you need to use a DHCP server that is NOT on the same VLAN as your DHCP clients, you have to use the helper-address command.  See below.  Here is a config from one of my customers that is using two different DHCP servers (with two different ranges that are split in the subnet, for redundancy).

The config on an ICX6610:
interface ve 21
 ip address
 ip helper-address 1
 ip helper-address 2
