Configuring weighted-round-robin weights

By default, in active-active HA mode the weighted round-robin schedule assigns the same weight to each FortiGate unit in the cluster. Once the cluster is configured to use the weighted round-robin schedule, you can use the set system ha weight command to configure a weight value for each cluster unit. The weight value sets the maximum number of connections that are sent to a cluster unit before a connection can be sent to the next cluster unit. You can set weight values to control the number of connections processed by each cluster unit. One use for this technique would be to reduce the number of connections processed by the primary cluster unit, by increasing the weight assigned to the subordinate cluster units.

Weight values are entered in order according to the priority of the units in the cluster. For example, if you have a cluster of 3 FortiGate units, you can enter the following command to configure the weight values for each unit:

set system ha weight 1 3 3

This command has the following results:

•The first connection is processed by the primary unit

•The next three connections are processed by the first subordinate unit

•The next three connections are processed by the second subordinate unit

The subordinate units will process more connections than the primary unit, and both subordinate units will on average process the same number of connections.
