estimados, soy nuevo en el foro y necesito aclarar una duda, me gustaria enternder bien que hace este parametro set mtu-override enable

gracias

hola,


mtu-override
"Select enable to use custom MTU size instead of default
(1 500). This is available only for physical interfaces and some
tunnel interfaces (not IPsec).
If you change the MTU size, you must reboot the FortiGate unit
o update the MTU values of the VLANs on this interface.
Some models support MTU sizes larger than the standard
1500 bytes. "

mtu
"Set a custom maximum transmission unit (MTU) size in bytes.
Ideally set mtu to the size of the smallest MTU of all the
networks between this FortiGate unit and the packet
destination.
<mtu_bytes> valid ranges are:
• 68 to 1 500 bytes in static mode
• 576 to 1 500 bytes in dhcp mode
• 576 to 1 492 bytes in pppoe mode
• up to 9 000 bytes for NP2-accelerated interfaces
• over 1 500 bytes on high end FortiGate models on some
interfaces.
If you enter an MTU that is not supported, an error message
informs you of the valid range for this interface.
In Transparent mode, if you change the MTU of an interface,
you must change the MTU of all interfaces to match the new
MTU.
If you configure an MTU size larger than 1 500 on your
FortiGate unit, all other network equipment on the route to the
destination must also support that frame size.
You can set the MTU of a physical interface and some tunnel
interfaces (not IPsec). All virtual interfaces inherit the MTU of
the parent physical interface.
The variable mtu is only available when mtu-override is
enabled."
