• Go to the Network devices section on the System Settings page.
• Click the Edit button next to an interface to display the interface information.
• Enable/disable DHCP. If DHCP is enabled, the interface IP address and DNS servers will be allocated by DHCP. IP addresses which have been allocated by DHCP cannot be edited and are shown on this page for information only.
• If DHCP is not enabled, set the IP address and subnet mask in the Addresses field, using CIDR notation.
• Optionally, set the default gateway in the Gateway field.
• Optionally, set the firewall zone in the Firewall zone field. This can be set to control, data or control & data (public).

• To set NTP as the time source, click on the Make active button, then click the Save button at the bottom of the page to save the change.

Configure active-backup bonded management interfaces for redundancy

These instructions show how to configure bonded management interfaces using the two 1G onboard NICs available on the E50 and E60 servers. These instructions assume that the eno8303 interface is already configured and working as the control interface.

Carry out the following commands using SSH or on the terminal:

sudo nmcli connection add type bond con-name bond0 ifname bond0 bond.options "mode=active-backup"

sudo nmcli connection add type ethernet slave-type bond con-name bond0-eno8303 ifname eno8303 master bond0

sudo nmcli connection add type ethernet slave-type bond con-name bond0-eno8403 ifname eno8403 master bond0

Configure the IP address of the bond interface. This can be either allocated via DHCP or assigned a static IP address.

sudo nmcli connection modify bond0 ipv4.method auto

sudo nmcli connection modify bond0 ipv4.addresses 192.168.1.42/24 ipv4.gateway 192.168.1.1 ipv4.dns "192.168.1.99,192.168.1.98" ipv4.method manual

sudo nmcli connection down eno8403 && sudo nmcli connection down eno8303 && sudo nmcli connection up bond0

sudo nmcli connection delete eno8403

sudo nmcli connection delete eno8303

sudo firewall-cmd --permanent --change-zone=bond0 --zone=control

sudo firewall-cmd --reload

Bonded network interface configuration will be retained on reboot and upgrade if the instructions above have been followed correctly.

Rebooting after configuration is recommended to confirm that in the event of reboot or power failure the networking continues to function.
