2824 support for multiple helper-address entries (DHCP relay)

Does the Procurve switch support configuring multiple DHCP servers for DHCP relay? I'd like to be able to configure a primary and back DHCP server. The CLI docs only show a single command "ip helper-address ", but don't say whether you can configure multiple entries. The 2900 docs explicitly state that after the example (i.e. "You can configure up to 256 IP helper addresses in the switch."), but the 2824 doc doesn't specify that...

Thanks in advance,
Steve

Hi Steve,

I just tried this running I.08.98 and was able to add 16 helper-addresses before it gave me an error.

Just found this in the release notes:

Maximum Number of Entries: The number of UDP broadcast entries and IP helper addresses
combined can be up to 16 per VLAN, with an overall maximum of 256 on the switch. (IP helper
addresses are used with the switchâ s DHCP Relay operation.
