External DHCP server is not able to assign IP when using 802.11 WPA2 AES

Hi
New to Aruba here. I am having an issue where an external DHCP server is not able to assign IP when using 802.11 WPA2 AES. If I test using Open Authentication the DHCP does assign an IP so it does work. Radius server authenticates too.
Looking at the Controller logs only has "Received DHCP packet from Datpath..."
Not sure where to proceed from here, any clues would be appreciated.
Thanks DL77

The encryption type should have no bearing on whether DHCP would work; but the role and/or VLAN assignment may.

 

Are both using the same role and both using the same VLAN?   For the open network, it would be "Initial Role"; for the 802.1X network it will be the "802.1X Authentiction Default Role"

Thanks for responding.

 

The roles are different.  For Open it is Guest, for 802.1X it is Employee I set up previously.  I changed it to Guest and it does work.  I did follow the guide for setup so I am not sure why DHCP doesn't work

I have attached to make it easier to read.

DHCP will not be allowed in that setup.  You need a line that reads:

 

any any svc-dhcp permit

 

The reason is b/c the client does not have an IP at the time of connection, so the source needs to be "any" not, "172.17.0.0 255.255.255.0"

Perfect thanks for pointing that out.  I will look into the rules further.

 

Cheers
