FortiSwitch Trunk interface, "bundle" setting explained

[J_Andersen]

Hi,

I came across this CLI command; set bundle enable/disable.

Can anyone explain to be what this does?

Adding member-ports to a trunk interface, and choosing the LACP mode already "bundles" physical ports to one logical port, so what is the "bundle" command used for?

Kind regards

Bundling provides additional tunning of the aggregation link, by allowing you to specify the minimum/maximum number of member ports you want up for your trunk to be active. When it is enabled (i.e. set bundle enable), new CLI directives min_bundle and max_bundle become available to specify these thresholds. Note that if the number of member ports is greater than the max_bundle value, the extra ports are set in standby mode and will be active only when one of the member ports is lost.
