FortiLink VLAN Optimization

Hello

I have FGT 200E OS 7.0.14 with two FSW 124F OS 7.2.7.

Multiple VLANs are needed on the switches (lets say 10, 11 and 12) but only one must be on FortiLink (VLAN 10), especially on the inter-switches link. This is because of some topology concerns (not show on the diagram).

Found some info on FortiLink admin guide but it is not well explained.

So it seems the command that may help is the following but I'm not sure if it will also filter VLANs on the ISL.

config switch-controller global
set vlan-optimization enable
end

config switch-controller vlan-policy
set fortilink FortiLink
set allowed-vlans VLAN-10
end

 

If any one has tested it or knows the right solution then any useful info would be appreciated.

Hi @AEK - Haven't tested this yet cos I don't have a FortiSwitch on my side, but you can try these guides. One is a bit old, but you can still give it a whirl:

Hi Ricky

Thanks for your feedback. Yes in fact the link you shared is the one from where I got the info (section "Changing the VLAN configuration mode"), but without enough details, so actually I'm wondering if the commands I shared are correct for my need.

Hi @AEK - I see. Apologies, but I'm out of ammo regarding this cos I don't have a device to practice on. But perhaps someone from the FortiSwitch Team will notice this and answer your question so we can both learn :)

Best,
