We are currently moving all our Cisco switches to Aruba switches. Around 40 switches in all. Everything works just swell except we have to keep around ten Cisco switches to keep our Cisco APs on. I cannot for the life of me find out how to get clients to connect to the Cisco APs when the APs are connected to our Aruba switches. It looks like clients can connect, but are not able to get DHCP. Can anyone point me in the right direction? ip helper is set up. Spanning tree is disabled. I am relatively new (brand new) to Aruba/HPE switches.
Any help would be greatly appreciated.

What may help you is the Cisco HPE CLI comparison guide: https://community.arubanetworks.com/t5/Education-A
Also, if you have problems converting your current Cisco config into HPE Aruba/Provision config it might help if you can post your current config on the Cisco side, at least the interface config, the vlan interface config and the routing config. That may people help to understand what is configured on the old switch and not on the new switch and prevents your clients network connectivity. My guess would be that on the current switches you have tagged VLANs (switchport trunk allowed-vlan) configured, and not on the new switches, where you go in the vlan, then use the tagged 10-18 command to tag the vlan on ports 10-18; which makes clients isolated from the network. It is the other way around, interfaces configured on the vlan, instead of vlans on interfaces; but you can achieve the same.
If you have urgent issues, please contact your Aruba partner or Aruba TAC.
