- <para>The final three configurable settings within the <guilabel>Identity</guilabel> dialog: the first below the name field is a text-entry field where you can specify a MAC (Media Access Control) address, and the second allows you to specify a cloned MAC address, and the third allows you to specify the MTU (Maximum Transmission Unit) value. Normally, you can leave the <guilabel>MAC address</guilabel> field blank and the <guilabel>MTU</guilabel> set to <userinput>automatic</userinput>. These defaults will suffice unless you are associating a wired connection with a second or specific NIC, or performing advanced networking. In such cases, see the following descriptions:</para>

- <para>Network hardware such as a Network Interface Card (NIC) has a unique MAC address (Media Access Control; also known as a <firstterm>hardware address</firstterm>) that identifies it to the system. Running the <command>ip addr</command> command will show the MAC address associated with each interface. For example, in the following <command>ip addr</command> output, the MAC address for the <guilabel>eth0</guilabel> interface (which is <systemitem class="etheraddress">52:54:00:26:9e:f1</systemitem>) immediately follows the <computeroutput>link/ether</computeroutput> keyword:</para>

- inet6 fe80::5054:ff:fe26:9ef1/64 scope link
- valid_lft forever preferred_lft forever</screen>
- <para>A single system can have one or more NICs installed on it. The <guilabel>MAC address</guilabel> field therefore allows you to associate a specific NIC with a specific connection (or connections). As mentioned, you can determine the MAC address using the <command>ip addr</command> command, and then copy and paste that value into the <guilabel>MAC address</guilabel> text-entry field.</para>
- <para>The cloned MAC address field is mostly for use in such situations were a network service has been restricted to a specific MAC address and you need to emulate that MAC address.
