Question

how to stack fortiswitch?

do the fortiswitch's support stacking ? i am speaking of traditional stacking where all switch are managed via single ip address and I can configure ports from any stack member thru a single mgmt ip . 

 

what about stacking bandwidth? do we have any dedicated stacking ports or is everything done thru the ports on the front of the switch? 

 

example if i have a 3 x 24 port 1G copper switch with no uplink ports how would i stack these 3 switches?

 

Is daisy chain my only option?

Hi @nflnetwork29 

 

Yes FortiSwitch support stacking and it is called MCLAG group and each FortiSwitch is an MCLAG peer but this depends on your FortiSwitch model.  Not all FortiSwitches support this feature..

The general "stacking" (Juniper's Virtual Chassis) and "MCLAG/MC-LAG/MLAG" are two different things. Some providers like Cisco, Juniper, and others might support both depending on models. Below is one of some explanations for the differences you can find online. FSW supports only MCLAG, not stacking.

Hi @Toshi_Esumi 

 

Vendors have different name in Fortinet a FSW stack is just a group of FSW managed by the same FortiLink interface..I think here @nflnetwork29  refer to something like cisco stackwise technology

 

Thanks

There aren't really any ways to 'stack' FortiSwitches in the traditional way. If you are managing them from the FortiGate, they each need discrete IPs to talk to. You don't have to use daisy-chaining if you manage them according to this document: https://docs.fortinet.com/document/fortiswitch/7.0.8/devices-managed-by-fortios/801202/single-fortigate-unit-managing-multiple-fortiswitch-units-using-a-hardware-or-software-switch-interface
