FortiSwitch 548d to replace Cisco 2960 access switch?

I just received a 548d to test with. I would like to configure it as an access switch, plugging into my Cisco core 9300.

On the Cisco side, I would typically configure something like switchport mode trunk switchport trunk native vlan X

On the uplink port to the core. And I’d assign an IP to VLAN X. From that point, I could SSH to the access switch.

I’ve been unsuccessful trying to accomplish the same on the 548d.

I created VLAN X and assigned an IP address to it. Then I assigned VLAN X as the native VLAN for the uplink port. However, I cannot ping the assigned IP address.

I did notice the link light on the 548 is green, but the Cisco side is blinking amber. I’ve tried a couple different STP settings on both sides unsuccessfully.

Am I missing something easy here, or going about the configuration wrong?

Thank you!

Hello @ugenswani ,


                   Thank you for using the Community Forum. I will seek to get you an answer or help. We will reply to this thread with an update as soon as possible.

Thanks and regards,


Thank you for providing the details, so vlanX is native vlan on both FSW port and Cisco port.

vlanX is a layer3 vlan on FSW.

Can you try to map vlanX as native vlan on FSW internal interface as well?
