When deploying updates, Panorama notifies the managed appliances
(firewalls, Log Collectors, and WildFire appliances) that updates
are available and the appliances then retrieve the update packages from
Panorama. By default, managed appliances retrieve updates over the
management (MGT) interface on Panorama. However, if you want to
reduce the traffic load on the MGT interface by using another interface
for appliances to retrieve updates, you can
Configure
Panorama to Use Multiple Interfaces.
