How to validate that the ISL is working properly in FortiSwitch & FortiGate

[StevenT]

Hi everyone,

Have anyone got any clue on how to validate that the configure ISL is working fine for FortiSwitch & Fortigate?

Thanks in advance.

 HI @StevenT ,

You can verify the FortiSwitch status from Fortigate by going to Security Fabric > Physical Topology > FortiSwitch .

You can check the Fortilink interface status with command :

execute switch-controller get-conn-status <FortiSwitch_serial_number>

A quick summary is shown with the command:

GW # execute switch-controller diagnose-connection S108xxxx

Fortilink interface ... OK
port5 enabled

DHCP server ... OK
port5 enabled

...

Fortilink
Status ... SWITCH_AUTHORIZED_NOT_CONNECTED
Last keepalive ... syncing
