OK, really dumb question, but can someone give me a diagram of how this would look to physically link four fourtiswitches to each other and the Fortigate with the last switch in standby? I am having a hard time translating this to a physical configuration. Thanks.
Single FortiGate unit managing a stack of several FortiSwitch units
The FortiGate unit connects directly to one FortiSwitch unit using a physical or aggregate interface. The remaining FortiSwitch units connect in a ring using inter-switch links (that is, ISL).
Optionally, you can connect a standby FortiLink connection to the last FortiSwitch unit. For this configuration, you create a FortiLink Split-Interface (an aggregate interface that contains one active link and one standby link).
