2. Click Save at the bottom of the page.

Set IP addresses, subnet masks, gateway address, DHCP, and firewall zone

1. Go to the Network devices section on the System Settings page.
2. Click the Edit button next to an interface to open its settings.
3. Enable or disable DHCP. When DHCP is enabled, the interface IP address and DNS servers are allocated automatically. DHCP-allocated values cannot be edited and are shown for reference only.
4. If DHCP is disabled, enter the IP address and subnet mask in the Addresses field using CIDR notation.
5. Optionally, enter the default gateway in the Gateway field.
6. Optionally, set the firewall zone in the Firewall zone field. Valid values are control, data, or control & data (public).
7. Click Confirm, then click Save at the bottom of the page.

Set DNS addresses

1. Go to the DNS section on the System Settings page.
2. Click the Edit button next to an interface to open its DNS settings.
3. If DHCP is disabled, add at least one DNS server in the Addresses field using CIDR notation. DNS servers allocated by DHCP cannot be edited and are shown for reference only.
4. Click Confirm, then click Save at the bottom of the page.

Set time synchronization

Configure active-backup bonded interfaces for redundancy

These instructions show how to configure bonded management or data interfaces. The example commands use the two 1G onboard NICs available on the E50 and E60 servers, and assume that the eno8303 interface is already configured and working as the management interface.

Run these commands using SSH or directly 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

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

The bonded network interface configuration persists on reboot and upgrade when you follow the instructions above.

Rebooting after configuration is recommended to confirm that networking continues to function after a reboot or power failure.
