how to configure DHCP relay on HP procurve switch

Is this for DHCP relay across VLANs or network segments?

it is for DHCP across Vlans

The minimum requirements for DHCP Relay Operation are:

1. DHCP Relay is enabled on the routing switch (the default setting);
2. A DHCP server is servicing the routing switch;
3. IP Routing is enabled on the routing switch;
4. There is a route from the DHCP server to the routing switch and back;
5. An IP Helper address is configured on the routing switch, set to the IP address of the DHCP server on the VLAN connected to the DHCP Client.
DHCP relay is enabled by default. If it has been disabled, it can be re-enabled simply by issuing the command:

ProCurve Switch(config)# dhcp-relay

Next, configure the IP Helper Address on VLANs where clients will reside:

ProCurve Switch(config)# vlan 2
ProCurve Switch(vlan-2)# ip helper-address <ip address>

ProCurve Switches supporting DHCP relay are:


Switch 8212zl
Switch 6400cl
Switch 6200yl
Switch 6108
Switch 5400zl
Switch 3500yl
Switch 5300xl
Switch 3400cl
Switch 4200vl
Switch 2900
Switch 2800
Switch 2600
In addition, the Secure Router 7000dl series supports DHCP relay, as do the Switch zl and xl Wireless Edge Services modules.

Any this what i am trying to achieve .  Getting the Avaya IP 4600 phone to obtain IP address from a DHCP server

1.      The phone boots up in the DATA VLAN and request DCHP addressing.
2.      The DHCP server responds on the DATA VLAN on SSON number 146/242 with ONLY the VOICE VLAN number e.g. 2.
3.      The phone statically configures itself in the VOICE VLAN and reboots.
4.      The phone boots up in the VOICE VLAN and request DHCP once again.
5.      The DHCP-Relay feature on the HP switches relays the DHCP request to the DHCP server on the DATA VLAN.
6.      The DHCP server responds on the DATA VLAN on SSON number 146/242 with the call server details (S8300) etc.
7.      The HP Procurve relays the details to the Phone on the VOICE VLAN.
8.      The phone registers and logs in on the VOICE VLAN.


 

The phone statically configures itself in the VOICE VLAN and reboots..

Does this mean you have it set to pull something off a TFTP?

1. phone should boot up and hit the TFTP and pull it's new configuration
2. it should boot up with new configuration that tells it that it is on VLAN 2 and will ARP VLAN2
3. Your DHCP relay will then relay the message to VLAN1 so it can hit the DHCP server
4. You will need to configure the DHCP with MAC addresses so it knows what addresses it is going to give the phones other wise it will be handing out VLAN1 address to VLAN2 devices.
