  • 1.  Licenses in a VX9000 cluster

    Posted 01-09-2018 15:08
    Hi,

    We'd like to create a cluster of two VX9000 instances running at separate physical locations as part of redundancy.

    There will be a total of 250 APs.

    Active VX - 1x VX-9000-APPLNC-LIC and 2x VX-9000-ADP-64
    Standby VX - 1x VX-9000-APPLNC-LIC

    This should give us a total of 256 licenses. If the active VX goes down, do we still have 256 licenses, they should be shared?

    Thanks,

    Best regards.

    Hi Vedran,

    Correct, the AP licenses will be shared and moved to secondary in a failover scenario . Please note however that both VX9000s within the cluster need to have appliance licenses.

    Yes, you have the license count on booth systems. Also if you reload the other VX.

    Only change cluster settings, if one of booth is offline.

    There is a limit of x days, if the other cluster member is offline, for the cluster license. But it was high, like 90 or 180 days.

    The limit is 100 days.

    If you split licenses 50/50 you would have 128 licenses per VX, but 256 total. That means you could have 256 APs on VX#1 and 0 on VX#2 or any combination thereof. It is preferable to adopt all APs to one of the two VX and run the cluster in active/standby.

    Hi Vedran,

    Kindly add our cluster document as the following URL:
    https://documentation.extremenetworks.com/ExtremeWireless/CLUSTER_CONFIGURATION_HTG_REV1.2_EN.pdf

    In WiNG 5.x two controllers can be part of a cluster for redundancy for services such as:
    • Access Point Adoption
    • License Sharing
    Best regards
