    FortiGate hardware limitation

    FortiGate hardware limitation

    FortiOS 5.4.0 reported an issue with the FG-92D model in the Special Notices > FG-92D High Availability in Interface Mode section of the release notes. Those issues, which were related to the use of port 1 through 14, include:

    • PPPoE failing, HA failing to form.
    • IPv6 packets being dropped.
    • FortiSwitch devices failing to be discovered.
    • Spanning tree loops may result depending on the network topology.

    FG-92D does not support STP. These issues have been improved in FortiOS 5.4.1, but with some side effects with the introduction of a new command, which is enabled by default:

    config global

    set hw-switch-ether-filter <enable | disable>

    When the command is enabled:
    • ARP (0x0806), IPv4 (0x0800), and VLAN (0x8100) packets are allowed.
    • BPDUs are dropped and therefore no STP loop results.
    • PPPoE packets are dropped.
    • IPv6 packets are dropped.
    • FortiSwitch devices are not discovered.
    • HA may fail to form depending the network topology.
    When the command is disabled:
    • All packet types are allowed, but depending on the network topology, an STP loop may result.
