Can I delete "lan" Hardware Switch in 40F

[johnlloyd_13]

hi,

just wondering if i can delete the "lan" hardware switch in a fortigate 40F?

can't seem to delete it even when it's disabled.

i'm trying to do this setup:

WAN: internet/ISP

A: HA

port 1: MGMT (out of band)

port 2 and 3: 802.3AD aggregate/Port-Channel to switch

the port-channel interface (ports 2 and 3) will be my "inside" interface with a private layer 3 IP.

is this scenario possible? appreciate your advise.

Hi John,

Make sure there are no references for the hardware interface while deleting.

However, share the error you are getting while deleting the interface.

WAN: internet/ISP

A: HA

port 1: MGMT (out of band)

port 2 and 3: 802.3AD aggregate/Port-Channel to switch

the port-channel interface (ports 2 and 3) will be my "inside" interface with a private layer 3 IP.

The above scenario is possible.

hi,

i can't remove "lan2" in the "lan" hardware switch.

getting a "this field is required" under the interface member.

originally lan2 and lan3 were added here.

how can i remove lan2 and delete the "lan" hardware switch interface?

Hi,

if you have not reference, you can delete the hardware switch from list interface. The interface lan2 will come back in list interface. You can not have a hardware switch without an interface.

hi,

i saw a default source NAT firewall policy.

changed source interface to my new portchannel inside interface.

the "delete" option was available for the lan hardware switch (lan2).

While I'm not a Fortinet expert, it's generally advisable to be cautious when altering hardware configurations, especially on network devices. Deleting the "lan" hardware switch might have unintended consequences. Ensure you have a solid backup before attempting major changes. It's also worth consulting Fortinet's documentation or community forums for specific advice on your FortiGate 40F model. Good luck with your setup! blumgi rocket
