Integrated Dell Remote Access Controller 9 User's Guide

Configuring the network settings

1. Under Enable NIC, select Enabled.
2. From the NIC Selection drop-down menu, select one of the following ports based on the network requirement:
   NOTE:This option is not available in MX platforms.

   • 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. 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 to manage the network traffic.

     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 servers with four NDC ports, all four LOM options are available.

   NOTE:Shared LOM is not supported on the Intel 2P X520–k bNDC 10 G if they are used in a full-height server with two NDCs because they do not support hardware arbitration.
3. From the NIC Selection drop-down menu, select the port from which you want to access the system remotely, following are the options:
   NOTE:This feature is not available in MX platforms.

   NOTE:You can select either the dedicated network interface card or from a list of LOMs available in the Quad port or Dual port mezzanine cards.

   • Chassis (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. 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 to manage the network traffic.

   • For Quad port cards—LOM1-LOM16
   • For Dual port cards—LOM1, LOM2, LOM5, LOM6, LOM9, LOM10, LOM13, LOM14.
4. 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:This option is disabled if NIC Selectionis set to Dedicated.

   NOTE:When using the Failover network settings, it is recommended that all the LOM ports to be connected to the same network.
   For more details, refer to the section Modifying network settings using web interface
5. Under Auto Negotiation, select On if iDRAC must automatically set the duplex mode and network speed.
   This option is available only for dedicated mode. If enabled, iDRAC sets the network speed to 10, 100, or 1000 Mbps based on the network speed.
6. Under Network Speed, select either 10 Mbps or 100 Mbps.
   NOTE:You cannot manually set the Network Speed to 1000 Mbps. This option is available only if Auto Negotiation option is enabled.
7. Under Duplex Mode, select Half Duplex or Full Duplex option.
   NOTE:This option is disabled if Auto Negotiationis set to Enabled.
   NOTE:If network teaming is configured for the host OS using the same network adapter as NIC Selection, then the Failover Network should also be configured. NIC Selection and Failover Network should use the ports that are configured as a part of the network team. If more than two ports are used as part of the network team, then the Failover Network selection should be "All".
8. Under NIC MTU, enter the Maximum Transmission Unit size on the NIC.
   NOTE: The default and maximum limit for MTU on NIC is 1500, and the minimum value is 576. An MTU value of 1280 or greater is required if IPv6 is enabled.
