The network interface controller ( NIC) uses the MAC address as its assigned unique identifier within an existing network segment. The following command output for Cluster_2 shows the same current hardware address for port1 as for the internal interface of Cluster_2, indicating a MAC address conflict.The term MAC Address is a derived abbreviation for Media Access Control Address. For example for one of the units in Cluster_1:įGT60B3907503171 # get hardware nic internalĭuring HA operation the current hardware address becomes the HA virtual MAC address, for example for the units in Cluster_1: You can also use the diagnose hardware deviceinfo nic  command to display both MAC addresses for any FortiGate interface.īefore HA configuration the current and permanent hardware addresses are the same. The command displays a great deal of information about the interface so you may have to scroll the output to find the hardware addresses. For some interfaces the current hardware address is displayed as MAC. You can use this command to display the current hardware address as Current_HWaddr and the permanent hardware address as Permanent_HWaddr. Depending on their hardware configuration, this command may display different information for different interfaces.

This command displays hardware information for the specified interface. You can use the get hardware nic command to display both MAC addresses for any FortiGate interface. You cannot change an interface MAC address and you cannot view MAC addresses from the system interface CLI command. The macaddr option is not available for a functioning cluster. For a FortiGate unit not operating in HA, you can use the following command to change the current hardware address of the port1 interface:įor an operating cluster, the current hardware address of each cluster unit interface is changed to the HA virtual MAC address by the FGCP. The current hardware address is the address seen by the network. The current hardware address can be changed. The permanent hardware address cannot be changed, it is the actual MAC address of the interface hardware. D i s p l ay i n g the virtual MAC addressĮvery FortiGate unit physical interface has two MAC addresses: the current hardware address and the permanent hardware address.
