This article provides some good practices, for a standalone FortiSwitch.
Scope
Standalone FortiSwitch
Solution
Disable auto-network: FortiSwitch is going to send FortiLink packets by default, trying to find a FortiGate where it can be controlled. This behavior can be modified with the next commands,
config switch auto-network set status disable end
Change the LLDP profile from 'default-auto-isl' to default on physical ports: By default, FortiSwitch has configured the LLDP profile 'default-auto-isl' on all physical ports. The intention of this is when connecting to a new FortiSwitch, they negotiate its LAG trunk. This behavior is not expected in standalone mode, so, it is a good practice to change the LLDP profile on all physical ports. It is possible to use the 'default' LLDP profile instead.
This is an example of how to change it:
config switch physical-port edit "port1" set lldp-profile "default" next
end
Do not allow all VLANs on trunks: Is a generally good practice to only allow the VLANs that need to cross to any other switch. This is the command needed to limit the VLANs on the trunk interface
config switch interface edit "Trunk1" set allowed-vlans 10,20,40,99 next end
