Aruba 8.4.0 Mobility Master install with redundancy


Boot and configure basic settings: ports, up link VLAN, username and password

Configure VRRP on the primary and secondary mobility master. Information on Virtual Router Redundancy Protocol (VRRP) can be found here

Once VRRP has been configured master redundancy between the two mobility masters must be configured. This solution creates redundancy between two Mobility Masters to form an primary-standby Mobility Master pair. Configuration from the master is synchronized from primary to secondary. Database synchronization: Ensures that the databases (e.g. license, WMS, AP, User, etc.) are synchronized between the two MMs.

The MM redundancy feature adds value to the deployment, but you must be CAREFUL! DO NOT mistakenly set the unsynchronized standby MM VRRP to a higher priority than the active MM. If you do, the standby MM becomes the ACTIVE MM, and its BLANK config and databases are synchronized over to the active MM. This will cause the existing database to be overwritten. Make sure that you set a higher priority on the existing MM.

Master redundancy –

Once the configuration has been completed the primary mobility master can be accessed via https/ssh using the configured VRRP IP address of

Configurations on the secondary mobility master must be configured on the device itself NOT from the primary mobility master.

Secondary mobility master

The next blog post –here– will focus on configuring communication between the mobility master and the Aruba controllers where are known as the managed devices (MD) in Aruba OS 8.X
