Vlan probe shows no access

I have an AP330 sitting on port 8 (verified by mac address) of an HP L2 switch.  The switch has data, voice, and mgt vlans.  Voice is tagged on all access ports and data is untagged.  Mgt vlan is untagged on SPF ports.  I've tagged mgt vlan on port 8 and verified (by both CLI and web) that it active.  Yet vlan probe from the AP shows that mgt vlan is not available. 

Switch says it is and AP says it's not.  I'm confused.  What next?

All a VLAN probe does is it checks to see if DHCP is set up on a VLAN. This proves the VLAN is reachable and DHCP is working on the VLAN. They assume that because you have a VLAN, you will also have DHCP enabled.

Do you have DHCP enabled on the VLAN?

Also, because you are using VLANs you will need to have the port the AP is connected to set to be a trunk port.

Thank you.  DHCP must be the issue.  Currently, our APs pick up an IP from the site native (data)  vlan via DHCP.  I want to move the mgt interface over to the mgt vlan which spans our multi-site environ.  But all the switches use statics.  So I created the scope and was trying to test it when this came up.

As for the trunked port, we use HP's.  So I have all three vlans assigned to that port, with mgt and voice tagged and data untagged.  I believe that is correct.
