Aruba controller with DHCP server issue.

  • 1.  Aruba controller with DHCP server issue.

    Posted Oct 04, 2021 01:54 PM
    Hello everyone,

    I have a problem with my network and I'm stucked right now because I don't know how to proceed:

    We have a DHCP server in our network, and we have configured an aruba controller with another DHCP server because we've no been able to configure it as a relay. The problem is the wired network (LAN) is using the aruba controller dhcp server too. Is there any way to configure the controller as a relay? Or the avoid the LAN takes IPs from Wifi?

    Regards.

    If the Aruba Controller DHCP shares a layer 2 VLAN with that network, it cannot be stopped from providing dhcp outside of the controller on that VLAN.

    You have the option of creating a VLAN that only exists in the Aruba Controller, and point a route from your network to the ip address of the Aruba Controller for that network.  In that situation, DHCP on the Aruba Controller would only provide DHCP within that VLAN.
