When you have an LACP aggregated link and/or VLAN interfaces in a fortigate at what "level" are you supposed to set the MTU?
On our different generations of switches I have seen different behavior and I don't know which applies to Fortigate.
I have seen:
- Jumbo frames are set per vlan
- Jumbo frames are set per port (on the port level and not the lag level)
The FortiOS system interfaces table contains items for each port, vlan and lag so where am I supposed to set the mtu?
