We have 13 Tp Link access switch connected with one another and my actual plan is to have a core switch and connect all the access switch to it. Now, I found Fortinet 100F with 8 SFP port so I am planning to use this Fortinet 100F as core switch as well as NGFW and the remaining switch will be connected with ethernet cable. Kindly advise this idea is possible and what may be the disadvantage.
we might need more detail here (LACP, STP, HA...).
Generally it seems just possible. You can define the 8 ports in question (or more) as one "hardware switch" and use the rest for other operation, that would be quite flexible to use as firewall for example.
