So, you’re wondering why and how to get an “ip-helper” address on a Comware 3com system? I wish I could say “easy enough” but I would be fibbing and giving you false expectations. I will outline what you need to do below:
dhcp relay server-group 1 10.10.10.1
interface Vlan-Interface #
dhcp select relay
dhcp relay server-select 1
I am going to raise the FAIL flag on this because this is far too much work to get this working compared to other platforms that only require ONE command.
