What is a Master Device in Device Groups?

erantanen — Thu, 12 Apr 2012 16:12:59 GMT

What role does a Master Device in a Device Group play?

Is there special communication with the Master Device, as a dependency?

If the Master Device goes down, is there a re-negotiation?

Is this Master Device affected with the standup of HA?

Hi,

The device selected as the Master Device is used to gather user information. The gathered user and group mapping information is used for shared policy configiration.

Selecting a Master Device is not mandatory for Panorama operation. Again, if you would like to get the user information available on a PAN device on to Panorama for policy creation, then this option needs to be selected. This has nothing to do with HA.

Thanks,

Ahsan

What happens in the event of a failover on an HA pair- do you have to manually go in and set the master device again?

In case the master goes down then information will not be refreshed until it's back up again or until a new master is configured.

Note that when you change the master or set it to none, Panorama loses all the user and group information received from that firewall.
