    our controller is running out the number of ap it can support hence we will need to purchase a 2nd controller. Other than increased number of ap it can support is there any other advantages of having 2 controller?

    It all depends how you will use the 2nd controller and what model you purchase.

     

    Direct advantages are

    • Redundancy (Master-Local for example)
    • Load balancing of APs between the two controllers

    You can read through the following VRD to give you some insight

    What are you running with now?

    It really depends on the need of your campus and the amount of APs you are currenlty managing and the future growth , here's some examples :

     

    - To balance APs between the two that way your traffic doens't go to just one controller and also if one fails not every AP will be impacted.

     

    - Also if you need to perform maintenance on one of the controller you could move the APs over to the other one while you make changes

     

    - If you have enough licenses on each controller you can have those serve has active-backup/active-backup 

     

    Hopes this helps
