Network settings
To configure the Network Settings:
NOTE: For information about the options, see the iDRAC Settings Utility Online Help.
1. Under Enable NIC, select the Enabled option.
2. From the NIC Selection drop-down menu, select one of the following ports based on the network requirement:
● Dedicated — Enables the remote access device to use the dedicated network interface available on the Remote Access
Controller (RAC). This interface is not shared with the host operating system and routes the management traffic to a
separate physical network, enabling it to be separated from the application traffic.
This option implies that iDRAC's dedicated network port routes its traffic separately from the server's LOM or NIC ports.
About managing network traffic, the Dedicated option allows iDRAC to be assigned an IP address from the same subnet
or different subnet in comparison to the IP addresses assigned to the Host LOM or NICs.
NOTE: In blade servers, the Dedicated option is displayed as Chassis (Dedicated).
● LOM1
● LOM2
● LOM3
● LOM4
NOTE: In the case of rack and tower servers, two LOM options (LOM1 and LOM2) or all four LOM options are available
depending on the server model. In blade servers with two NDC ports, two LOM options (LOM1 and LOM2) are available
and on server with four NDC ports, all four LOM options are available.
NOTE: Shared LOM is not supported on the following bNDCs if they are used in a full — height server with two NDCs
because they do not support hardware arbitration:
● Intel 2P X520–k bNDC 10 G
● Emulex OCM14102–N6–D bNDC 10 Gb
● Emulex OCm14102-U4-D bNDC 10 Gb
● Emulex OCm14102-U2-D bNDC 10 Gb
● QLogic QMD8262–k DP bNDC 10 G
3. From the Failover Network drop-down menu, select one of the remaining LOMs. If a network fails, the traffic is routed
through the failover network.
For example, to route the iDRAC network traffic through LOM2 when LOM1 is down, select LOM1 for NIC Selection and
LOM2 for Failover Network.
NOTE: If you have selected Dedicated in NIC Selection drop-down menu, the option is grayed-out.
NOTE: Failover is not supported on shared LOM for the following Emulex rNDCs and bNDCs:
● Emulex OCM14104-UX-D rNDC 10 Gbx
● Emulex OCM14104-U1-D rNDC 10 Gb
● Emulex OCM14104B-U1-D rNDC 10 Gb
● Emulex OCM14104-N1-D rNDC 10 Gb
● Emulex OCM14104B-N1-D rNDC 10 Gb
● Emulex OCM14102-U2-D bNDC 10 Gb
● Emulex OCM14102-U4-D bNDC 10 Gb
● Emulex OCM14102-N6-D bNDC 10 Gb
NOTE: On Dell PowerEdge FM120x4 and FX2 servers, Failover Network is not supported for the chassis sled
configurations. For more information about the chassis sled configurations, see the Chassis Management Controller
(CMC) User’s Guide available at dell.com/idracmanuals.
NOTE: On PowerEdge FM120x4 servers, while configuring the Enhanced Network Adapter Isolation, ensure that LOM2
is disabled on the host system and is not selected for iDRAC NIC. For more information about the chassis sled
configurations, see the Chassis Management Controller (CMC) User’s Guide available at dell.com/idracmanuals.
