  • 1.  APs go down when trying to cluster conductor managed Controllers

    Posted Sep 26, 2024 09:17 AM

    Hello,

    Apologizing if this an RTFM kind of situation but I just was unable to find good instructions online. Followed the 8.2 and 8.9 John Schaap Video's instead. 

    Each time when I activate L2 clustering on my Aruba Virtual Controllers I am losing connectivity to my access-point(s). I am using AOS: 8.10.0.14_90752

    Here's an overview of the setup all running on ESXi although the switch below it is a hardware switch where the AP connects to

    VLANs used on Controller:
    Ge-0/0/0: access ports with VLAN 201
    Ge-0/0/1: trunk port with VLAN 202 and VLAN 25 (data VLAN for clients)
    I use an untagged VLAN for my APs and a tagged VLAN for the clients (25)

    I followed the instructions and created a cluster group.I tried two methods, one time like below, basically only setting the VMC IPs no groups or anything else. 

    The other time I set the group and added the VRRP-IPs for CoA

    Here's the VRRP configuration

    Whenever I set the cluster-profile at the Controller level everything goes south and I loose connectivity to the APs.

    Anyone have a suggestion for me? Thanks in advance

    You cluster based on the IP addresses assigned as the controller-ip, and the APs are going to communicate to those same IP addresses.  Not sure what you are trying to accomplish with the split networks but you are much better off handling all controller management and functionality and AP connectivity on a single VLAN.  Secondary interfaces can be used for the client VLANs.

    HI Carson,

    Thanks for that piece of information! Yes I guess it is that background of separating different functions to different IP subnets. I will change that and see what happens.

    After going to a simpler setup with just that one VLAN that has both the conductors and the controllers it worked directly, no issues.

    Thank you.
