link aggregation using port 15 and port 16
Hi, I was asked to cascade the port 16 or a Fortigate 200D to a Csico 2960-X L2 switch. Now my boss wants me to have a backup of port 15 in case port 16 goes down. So from ports 15 and 16 going to ports 23-24 of the Cisco 2960-X switch. I followed the following articles for me to link aggregate the 2 ports.

but in my cisco switch, it still shows that
LACP is currently not enabled on remote ports. Am I imssing something here?
Thanks
