When configuring HA, what indicates a higher priority for a device?

In the context of High Availability (HA) configurations, priority levels determine which device in a cluster will act as the primary (or master) and which will serve as the secondary (or slave). A higher priority is indicative of a device's preferred status in taking over when the primary device becomes unavailable.

When devices are configured with priorities in HA, the device with the highest numerical value is selected as the active primary. This means that if one device has a priority setting of, say, 200, and another is set to 150, the device with the 200 setting will take precedence in the HA setup. Therefore, the system prioritizes the device that is deemed more critical or capable of managing the network traffic effectively.

Lower numerical values do not signify higher priority—quite the opposite; they actually indicate lower priority. Similarly, an equal group ID does not influence which device becomes primary because it’s the designated priorities that dictate leadership in this scenario. Lastly, the firmware version does not play a role in determining priority; instead, it relates to the device functionalities and updates. Thus, when aiming for a device with higher priority, configuring it with a higher numerical value is the correct approach.
