    Anyone seen any issues on a 6000 controller, 63 code where the mgmt vlan is suddenly transissioning between forwarding/blocking, all other user vlans ok ??

    How is the interface configured on the switch and the Aruba Controller?

    How is spanning tree configured on the switch and the Aruba Controller?

    Do you have two links between the controller and the switch?

    Colin, no single link multiple controllers.  Been ok for months/years just the management untagged vlan going blocking/forwarding therefore the VRRP is getting screwed.   I suspect a bug but cant see anything in release notes. The other controller no issues.

    What changes were made before the issue started happening? If it has been good and you have not upgraded the code, it is the configuration of the controller or the switch.

    Yes I thought so also, they have disabled STP on the vlan and still no joy,   not sure if any other changes made however..

    stunshot,

     

    If you already removed it from the network, we can only speculate on what your issue is.  If you decide to put to back together, please contact support so that they can have live data needed to help you.
