Fortiswitch Stack

[rizaganda92]

Hi is anyone have try Fortiswitch Stack on 7.6.2 (Not MCLAG)

https://docs.fortinet.com/document/fortiswitch/7.6.2/fortiswitch-stacking-deployment-guide/383494/in...

I want to use FS648 as core switch, Is it better to use Fortiswitch stack or MCLAG?

The Fortiswitch will be used as Gateway for VLAN, OSPF Routing ( i have advance license) if using MCLAG i need to use VRRP will consume 3 IP at least, but i dont see much documentation or review for Fortiswitch stack

There is no such thing as a Fortiswitch stack. The only solution is called MCLAG which tells two physical switches to pretend to be one "virtual" switch. The main purpose is to allow downstream devices to connect to both MCLAG-switches with active-active portchannels without creating a network loop.

In this documentation

https://docs.fortinet.com/document/fortiswitch/7.6.2/fortiswitch-stacking-deployment-guide/383494/in...

it said we can stack the switch, 

FortiSwitch stacking allows up to four switches to operate as if they were one switch. 

i think its different with MCLAG, since we can use 2 until 4 switch as one switch

Hello,
for further information: stacking is a new feature within 7.6x FortiSwitchOS but only available for specific models, 624F/648F (fpoe and non-poe), like rizaganda92's ones.

Stacking and MCLAG are exclusive in the same setup; you have to choose.
Stacking is only supported in standalone switches .

If I were in your place, I'll check stacking documentation for  features/limitations.
As you mentioned advanced routing licences and another needs,  maybe MCLAG could be a more flexible option.

Hope it helps

Hi,

Thanks for the advise, yes actually I have go through the documentation however i think not much information given on the documentation, it mention L2 suppport, there are no L3 (routing, etc) ini supported features or limitation. 

I think i will go for MCLAG for now. 

Thanks
