dhcp server issue on Aruba 5412R zl2 with Aruba 2930F

[saifuddeentp]

Hi,

I need support for my dhcp issue. I have Aruba 5412R zl2 and Aruba 2930F switches. we have one  Aruba Mobility Controller also in this network.

To add the APs, i have enabled the dhcp server globally and enbled it on single vlan 620 and created dhcp pool only for this vlan ip range. Now the issue is with remaining DATA VLANs, which does not required dhcp. on those interfaces dhcp is working since i enabled it globally. i tried "no dhcp-server" those DATA Vlans still its randomly picking IP address from management VLAN . Please have a look on my running config, to sort out the issue
