Fortiswitch Multiport 3+

[rcpdkc]

Hello, I have a 1101f series firewall. I want to connect 6 fortiswitches. When I connect the switches over fortilink by jumping from each other, there is no problem and all of them get ip and the connection status is actively monitored. However, when I need to connect with different 6 ports of the firewall (due to the wiring structure of the building), I enter 6 ports into fortilink. When I connect the switches, they get ip first, but the connections go immediately. DHCP does not work and they cannot get ip. What is the reason for this?

In addition, I created a fortilink port as a Hardware Switch. When I put the ports into it, all switches get ip but only 2 of them seem to be active. I can reach the others but they do not seem active. What could be the reason for this?

The following topic was a solution for me, but the problem here is that I can connect to 6 fortiswitches, but only 2 of them seem to be active.

The document I gave in the link gives all the details required for the connection.

After applying the given document, it did not appear active except for 2 devices. Later, when I entered the fortiswitch interface, I saw that the time was incorrect. I entered the gateway address of the switches as ntp server and the time was corrected. Devices went online.

Nice catch.. Thanks for sharing the info.

Indeed, missing NTP leads in so much and diverse issues.

In the Fortiswitch interface, the default gateway must be written in the NTP server section at the bottom.
