Remove VLANs from Fortiswitch ISL Trunk
Hello everyone!
I would like to know if there is a way to exclude specific VLANs from passing inside a fortiswitch ISL trunk or to pass only management traffic between a specific ISL link.
By default fortilink passes all VLANs between Fortiswitches connected to each other. Yet, I have a requirement to not allow specific VLANs to pass through a ISL formed between 2 FortiSwitches, therefore forcing data traffic to go through a 3rd party switch connected to both of these Fortiswitches.
KB: https://community.fortinet.com/t5/FortiSwitch/Technical-Tip-Seperate-Inter-Switch-Link-ISL-between-Managed/ta-p/224568
states about separating the traffic, but my requirement does not need the second link to pass data. Is there a simpler way to achieve this? Did not want to go into modifying MSTP instances and all of that.
Thanks in advance for any suggestions and tips!
Regards
