The article below will teach you how to update the configuration settings of a NIC.
Global Networking NIC Settings
The following are the Global Settings for updating the configuration of a given NIC.
Name. The system name of the physical interface. This name is not editable.
IP Address. The network-layer IP address of the NIC. Supports both IPv4 and IPv6. This field is mandatory and the Netmask field must be set if DHCP is disabled.
Netmask/CIDR. The subnet mask of the NIC. Supports the network mask format or CIDR (0 to 32 bits) when using IPv4 or only CIDR format (0 to 128 bits) when using IPv6. This field is mandatory and the Address field must be set if DHCP is disabled.
Gateway. Default gateway in IPv4/IPv6 format used by the NIC.
MAC. The link-layer MAC address assigned to the NIC by its vendor. This is not editable.
IPv4 and IPv6 stacks are supported, taking into account that the Netmask and Gateway must be configured in the same stack as the IP. Once all the required changes are done, click the Apply button to save the new changes.
