Vlan Configuration with IP-helper on Procurve 2910al-24g

[JokeJong]

Hi everyone,
i have a HP Procurve 24port 2910 switch.
i have 5 lan I would like to segregate.
meaning, i will have 5 vlan.

vlan1 - default vlan (mgt) port 1
vlan2 - office - 10.10.1.*/24 port 2-6
vlan3 - library - 10.20.1.*/24 port 7-10
vlan4 - comlab - 10.30.1.*/24 port 11-15
vlan5 - guest - 10.40.1.*/24 port 16-20
vlan6 - guesthome - 10.50.1.*/24port 21-24

I am familiar with creating vlan and assigning addresses, I have already done so.

my vlan config will be
untagged ports for each of the vlan name and numbers all assigned.

question:
1) i want to put my DHCP Server (windows 2003 domain controller) - which happens to be my exchange server as well, on office vlan-2.
(say the address is 10.10.1.10) I created each scopes in the DHCP server, 10.(10-50).1.*
i have also assigned each vlan an address: 10.(10-50).1.1 for each vlan.


I know I am suppose to configure ip helper for each of the vlan, and each of the vlan will connect to vlan2-dhcp server(10.10.1.10) to get IP address for their subnet.

Can you guys guide me as to how i can do the settings for the switch please?

I followed one sample from: http://h40060.www4.hp.com/procurve/uk/en/pdfs/5300xl_dhcp_relay.pdf

but i think if i configure my server gateway to the switch IP, i need to do ip routing (which I don't want/intend to).

any help is appreciated. :)

You need to configure it as mentioned in the document, and if you want you can configure ACL to allow only traffic to the DHCP server between the VLANS

I did follow the configuration from the document, but it's not helping. I am not getting addresses in my other VLANs.

It would help us to see your switch config.

You mention you do not want to do routing on the 2910 switch, however, 'ip helper-address' only works when you have routing on the switch with the 'ip helper-address' command.
