Description

This article explains how to override the manufacturer-burned MAC address for a network interface.

Solution

The MAC address or MAC entry of a FortiGate unit network interface can be set with the following CLI command.

# config system interface
# edit int
# set macaddr <xx:xx:xx:xx:xx:xx>
# end

where <xx:xx:xx:xx:xx:xx> is the address to be set.

This command will override the factory-set MAC address of this network interface, by specifying a new MAC address in the format xx:xx:xx:xx:xx:xx.

This is only used for physical interfaces or the MAC entry may be set in the transparent mode.
