Users Guide

● 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 on page 92
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.
Common settings
If network infrastructure has DNS server, register iDRAC on the DNS. These are the initial settings requirements for advanced
features such as Directory services—Active Directory or LDAP, Single Sign On, and smart card.
To register iDRAC:
1. Enable Register DRAC on DNS.
2. Enter the DNS DRAC Name.
3. Select Auto Config Domain Name to automatically acquire domain name from DHCP. Else, provide the DNS Domain
Name.
For DNS iDRAC Name field, the default name format is idrac-Service_Tag, where Service_Tag is the service tag of the
server. The maximum length is 63 characters and the following characters are supported:
● A-Z
● a-z
● 0-9
● Hyphen (-)
