trunk access point remains red status

[matteocostanzo]

I configured trunks on my fortiswitch to structure the double port of my APs in LACP. on the access points I ran the same command:
cfg -a FAP_ETHER_TRUNK=2

but on a graphic level the trunk on the switch side remains red. I can see the switch through the firewall.

only the first AP installed sees the green trunk, the others remain red.

even the trunk to the firewall itself remains red despite all the ports connected in green. I don't understand why.

the firewall is updated to the latest firmware version available and everything else is updated too.

Hi,

Can you help me out with below output:-

conf switch trunk
show

diagnose switch trunk list

[matteocostanzo]

Can you write me the exact commands to launch and on which CLI: firewall, switch, AP??

[sjoshi]

the command mention above needs to be run on the FortiSwitch

[matteocostanzo]

I opened the switch cli and this is the message I get when running the command you described

# conf switch trunk

ambiguous command before 'switch'
Command fail. Return code 1

Can anyone help me with this please?

Whats the FAP model, FAP version, FSW model, FSW version?

Have you checked the link speed on both FortiAP ports if both the ports are negotiating at same speed? You can check this by entering below command on FSW:

FortiSwitch# diagnose switch physical-ports summary
