Hardware session synchronization LAGs must be static

FortiOS 7.2.4 only allows you to use a static mode LAG as the hardware session synchronization interface.

Example LAG configuration:

config system interface

edit HA-session-lag

set type aggregate

set lacp-mode static

set member port13 port14 port15 port16

end

Example HA configuration:

config system ha

set session-pickup enable

set hw-session-sync-dev HA-session-lag

end

You can only add a LAG with lacp-mode set to static as the hw-session-sync-dev and the CLI blocks you from changing the lacp-mode of the hw-session-sync-dev LAG to dynamic or passive.
