Server NIC Configuration
Server NICs
Two NIC modes are available for connection to the CIMC. In one mode, you can also choose an active-active or active-standby redundancy mode, depending on your platform.
NIC Mode
-
Dedicated—A connection to the CIMC is available through the management Ethernet port or ports.
-
Shared LOM—A connection to the CIMC is available only through the LAN On Motherboard (LOM) Ethernet host ports.
Note
In shared LOM mode, all host ports must belong to the same subnet. -
Shipping (if supported)—A connection to the CIMC is available through the management Ethernet port or ports using a limited factory default configuration.
Note
Shipping mode is intended only for your initial connection to the CIMC. Configure another mode for operation.
NIC Redundancy
-
None—Redundancy is not available.
-
Active-Active—All Ethernet ports operate simultaneously. This mode provides multiple paths to the CIMC.
-
Active-Standby—One port fails over to the other.
The available redundancy modes vary depending on the selected network mode and your platform. For the available modes, see the Installation and Service Guide for your platform.
Configuring Server NICs
Configure a server NIC when you want to set the NIC mode and NIC redundancy.
You must log in as a user with admin privileges to configure the NIC.
Configuring Common Properties
Use common properties to describe your server.
You must log in as a user with admin privileges to configure common properties.

Step 2 | On the Admin tab, click Network. |
Step 3 | In the Network pane, click the Network Settings tab. |
Step 4 | In the Hostname field, enter the name of the host. |
Step 5 | Click Save Changes. |
Configuring IPv4
You must log in as a user with admin privileges to configure IPv4.

Network Security Configuration
Network Security
The CIMC uses IP blocking as network security. IP blocking prevents the connection between a server or website and certain IP addresses or ranges of addresses. IP blocking effectively bans undesired connections from those computers to a website, mail server, or other Internet servers.
IP banning is commonly used to protect against denial of service (DoS) attacks. CIMC bans IP addresses by setting up an IP blocking fail count.
Configuring Network Security
Configure network security if you want to set up an IP blocking fail count.
You must log in as a user with admin privileges to configure network security.
