SSH To allow SSH connections to the CLI through this interface.
SNMP To allow a remote SNMP manager to request SNMP information by connecting to
this interface. See
TELNET To allow Telnet connections to the CLI through this interface. Telnet connections
are not secure and can be intercepted by a third party.
MTU
To improve network performance, you can change the maximum transmission unit
(MTU) of the packets that the FortiGate unit transmits from any physical interface.
Ideally, this MTU should be the same as the smallest MTU of all the networks between
the FortiGate unit and the destination of the packets. If the packets that the FortiGate
unit sends are larger, they are broken up or fragmented, which slows down
transmission. Experiment by lowering the MTU to find an MTU size for best network
performance.
To change the MTU, select Override default MTU value (1500) and enter the
maximum packet size. For manual and DHCP addressing mode the MTU size can be
from 576 to 1500 bytes. For PPPoE addressing mode the MTU size can be from 576
to 1492 bytes.
Note: In Transparent mode, if you change the MTU of an interface, you must change the MTU
of all interfaces to match the new MTU.
Log
Select Log to record logs for any traffic to or from the interface. To record logs you
must also enable traffic log for a logging location and set the logging severity level to
Notification or lower. Go to Log & Report > Log Config to configure logging locations
and types. For information about logging see
