Fortigate – Finding MTU of an interface

Recently I had the need to show the MTU of an Fortinet Fortigate firewall interface. By default, if there are no changes the MTU will be 1500. But in this case I needed to be able to show that the MTU was 1500.

Few commands I tried did not show the exact info I needed, for example- Get hardware nic port1 – showed lots of great info but not the MTU.

To get this info I needed to do an Ifconfig from the Fortigate. to do this I ran the command:

fnsysctl ifconfig -a port1     Port1 being the port I needed to get the info for. Check out the screenshot below. Lots of other great info such as dropped packets and MAC.



Dell FX2 console to internal switches

The Dell FX2 is a pretty awesome piece of hardware. I mostly only work on it from the networking side.

From the CMC you can console to each of your switch modules. I had a hard time finding documentation on the very simple command to do this. From doing a quick ? and scanning through each command I found “Connect” Pretty fast, and knew that would be it …. but connect to what?

I finally found from searching a different help command that you can do

Connect switch-1


connect switch-2

This will allow you to access each of your switches from the CMC. Check the below screenshot out.
