Command context

  • The command redundancy preferred-active-management is mutually exclusive with VSF. The preferred-management-module must be disabled to enable VSF on an ArubaOS-switch.

  • When a preferred module taking over as an Active module fails, a fail-over to another management module will occur. User intervention must rectify the cause for the failure or if a chassis reboot is attempted, the attempt may fail. In the case of a boot, there will be an extra redundancy switchover.
