Description This article explains details about port combination link aggregation group (LAG) support for FortiGate-600F and 601F hardware platforms.
Scope Any supported version of FortiGate.

Both the FortiGate-600F and 601F platforms support combining ultra low latency (ULL) ports (X5 to X8) and non-ULL ports (X1 to X4) as members in the same LAG. ULL ports (X5 to X8) are directly connected to NP7, while non-ULL ports (X1 to X4) are connected to NP7 through ISF.



If the device has multiple NP7 chips, all Ports defined in the LAG need to connect to the same NP7 chip.
