HP 2530 Switch DHCP Issues

I've got some new HP Aruba 2530-24G switches that I have updated to the latest software: YA.16.05.0004 and I'm having an issue getting the DHCP to work correctly. I have an additional VLAN on the switch that I would like to be configured via DHCP. This would normally be the management port/vlan.  I currently have both VLANs configured for DHCP. If I plug the ethernet into a port defind as DEAFAULT_VLAN, everything works fine. I get my DNS server, Gateway address, etc. If I plug the same ethernet into a port/vlan defined on another VLAN I only get the address.

This is the same DHCP server and in fact the same ethernet cable. I just move it to different VLANS.

Here is the configuration and log of the results:

What have I got configured wrong or does this not work?

You don't have a default gateway in the first example.

Re: HP 2530 Switch DHCP Issues

Yes I know. It is supposed to get it from the DHCP actions. As you can see in the 2nd try it was received. 

It seems that the VLAN that is marked as Primary is the only one that will propogate all of the DHCP settings.
