    I’ve encountered an odd situation. Im replacing Cisco APs with Aruba 215s. Now clients are unable to pickup DHCP, mostly windows clients. Smartdevices appear to be getting DHCP. We have the vlans, trunks configed properly, and are not exhausting the DHCP scope. Has anyone encountered this before or provide comments?

     Here is the Cisco Config before we replace the Cisco WAP with Aruba IAP:

    interface GigabitEthernet11/46

    description CISCO WAPS

    switchport

    switchport access vlan 180

    switchport mode access

    switchport nonegotiate

    switchport port-security violation restrict

    end

     

    Here are the changes to the the port when we add the Aruba IAP. We are making the port native Vlan 180: 

    interface GigabitEthernet13/42

    description ARUBA AP

    switchport

    switchport trunk encapsulation dot1q

    switchport trunk native vlan 180

    switchport trunk allowed vlan 180,188,313

    switchport mode trunk

    switchport nonegotiate
