    Is it possible to change the ARP Cache/ MAC Table settings on a Aruba 72xx series controller?

    We are experiencing an issue where the controller will lose access to it's DG and we believe it is an issue with the controller ARP and/or MAC tables.

    We believe the default is 300 secs (5 Minutes) on the Aruba Controller, is that correct?

    Correct and cannot be changed.  I would engage Aruba/HPE Technical Support if you believe you have a bug.
