Master Redundancy - DHCP Server sync

  • 1.  Master Redundancy - DHCP Server sync

    Posted Dec 05, 2018 08:51 AM

    Dear Experts,

     

    Can someone help to confirm if comments by Colin still hold true on latest version of 6.x? 

     

    https://community.arubanetworks.com/t5/Wireless-Access/Master-Redundancy-and-DHCP-Server/td-p/224849

     

    One of my customer has Cisco Nexus on core but he is afraid that using DHCP server on it will crash it. Also they rejected the idea of installing a separate DHCP server also. 

     

    Please advise if above link still holds true

    Definitely installing a dedicated DHCP server would be preferrable.

    However, you could split the scopes by excluding half on each controller. e.g.

     

    Controller 1:

    Network - 192.168.1.0/24

    Excludes - 192.168.1.128 - 192.168.1.254

     

    Controller 2:

    Network - 192.168.1.0/24

    Excludes - 192.168.1.1 - 192.168.1.127

     

    This will stop the controllers issuing duplicate IP addresses.
