Split DHCP and DHCP relay?

[kevinadams]

****OOPS.  Dupe post.  Forum is throwing errors and made me believe my post was lost.*****

I need to setup a split DHCP config with two servers but I can find no info on getting 4800G and 5500g switches with DHCP relay to acomplish this task.  They use DHCP relay currently to ship DHCP requests in their subnet up to the server subnet, but I don't know how to configure it for two DHCP servers.  Can anyone help with this or point me to good documentation as I've been able to find absolutly zero concerning this?

I can assign only one IP to each dhcp relay server group.


I can then only assign one dhcp relay group to a vlan interface.


This leads me to believe I can only assign one DHCP server per VLAN.  True?  False?

I found I was able to assing two IP's to the dhcp group of the 4800g switches by typing the command once for each IP I needed like:

dhcp relay server-group 1 ip 10.1.16.52


dhcp relay server-group 1 ip 10.10.50.89

The 5500g SFP needed it like this:

dhcp-server 1 ip 10.1.16.52 10.10.50.89

This is very poorly documented.
