Gigabit-Ethernet ================ .. admonition:: Galvanic Isolation The Gigabit-Ethernet interface is **galvanically isolated** to prevent ground-loops and increases overall system resilience. .. note:: Per default the Gigabit-Ethernet interface is configured for `DHCP `_. Configure Gigabit-Ethernet (1000BASE-T) for static IP using ``nmcli``: * Configure a static IP (on host computer) .. code:: bash sudo ifconfig eth0 192.168.1.2 netmask 255.255.255.0 * Check current IP configuration on X8. .. code:: bash ip addr show eth0 ... 3: eth0: mtu 1500 qdisc mq state UP group default qlen 1000 link/ether ee:89:d5:98:e7:01 brd ff:ff:ff:ff:ff:ff * Delete ``nmcli`` configuration for DHCP (on X8) .. code:: bash nmcli con del 'Wired connection 1' * Add ``nmcli`` configuration for a static IP (on X8) .. code:: bash nmcli con add type ethernet con-name 'static' ifname eth0 nmcli con mod 'static' ipv4.addresses 192.168.1.8/24 nmcli con mod 'static' ipv4.gateway 192.168.2.1 nmcli con mod 'static' ipv4.dns 8.8.8.8 nmcli con mod 'static' ipv4.method manual nmcli con up 'static' .. code:: bash ip addr show eth0 ... ip addr show eth0 3: eth0: mtu 1500 qdisc mq state UP group default qlen 1000 link/ether ee:89:d5:98:e7:01 brd ff:ff:ff:ff:ff:ff inet 192.168.1.8/24 brd 192.168.1.255 scope global noprefixroute eth0 valid_lft forever preferred_lft forever inet6 fe80::9361:a0f:f192:6199/64 scope link noprefixroute valid_lft forever preferred_lft forever
