Technical Tip: How to configure the aggregator mode for a FortiSwitch

[sreddi]

Description
In a LACP trunk, ports with the same negotiated speed are grouped into an aggregator.
Setting the aggregator mode allows to select the aggregator based on either the bandwidth or the number of links.

This article describes how to configure the aggregator mode for a FortiSwitch.

Scope
For version 6.4.2 and above.

Solution

# config switch-controller managed-switch
    edit <switch>
        # config ports
            edit "trunk_server1"
                set aggregator-mode {bandwidth | count}
                set vlan "default.13"
                set type trunk
                set mac-addr 90:6c:ac:de:35:fe
                set mode lacp-active
                set members "port11" "port12"
            next
        end
    next
end

Note.
Bandwidth: The aggregator with largest bandwidth is selected (Default).
Count: The aggregator with largest number of ports is selected.
