iDRAC can display the IPv4 and IPv6 addresses for all the interfaces configured on the Host OS.
Depending on how the Host OS detects the DHCP server, the corresponding IPv4 or IPv6 DHCP server address may not be
displayed.
Viewing network interfaces available on host OS using web
interface
To view the network interfaces available on the host OS using Web interface:
1. Go to System > Host OS > Network Interfaces.
The Network Interfaces page displays all the network interfaces that are available on the host operating system.
2. To view the list of network interfaces associated with a network device, from the Network Device FQDD drop-down menu,
select a network device and click Apply.
The OS IP details are displayed in the Host OS Network Interfaces section.
3. From the Device FQDD column, click on the network device link.
The corresponding device page is displayed from the Hardware > Network Devices section, where you can view the device
details. For information about the properties, see the iDRAC Online Help.
4. Click the
icon to display more details.
Similarly, you can view the host OS network interface information associated with a network device from the Hardware >
Network Devices page. Click View Host OS Network Interfaces.
NOTE: For the ESXi host OS in the iDRAC Service Module v2.3.0 or later, the Description column in the Additional
Details list is displayed in the following format:
<List-of-Uplinks-Configured-on-the-vSwitch>/<Port-Group>/<Interface-name>
Viewing network interfaces available on host OS using
RACADM
Use the gethostnetworkinterfaces command to view the network interfaces available on the host operating systems
using RACADM. For more information, see the iDRAC RACADM CLI Guide available at https://www.dell.com/idracmanuals.
Viewing FlexAddress mezzanine card fabric
connections
In blade servers, FlexAddress allows the use of persistent, chassis-assigned World Wide Names and MAC addresses (WWN/
MAC) for each managed server port connection.
You can view the following information for each installed embedded Ethernet and optional mezzanine card port:
Fabrics to which the cards are connected.
Type of fabric.
Server-assigned, chassis-assigned, or remotely assigned MAC addresses.
To view the Flex Address information in iDRAC, configure and enable the Flex Address feature in Chassis Management
Controller (CMC). For more information, see the Chassis Management Controller User's Guide available at https://
www.dell.com/cmcmanuals. Any existing Virtual Console or Virtual Media session terminates if the FlexAddress setting is
enabled or disabled.
NOTE:
To avoid errors that may lead to an inability to turn on the managed system, you must have the correct type of
mezzanine card installed for each port and fabric connection.
The FlexAddress feature replaces the serverassigned MAC addresses with chassisassigned MAC addresses and is
implemented for iDRAC along with blade LOMs, mezzanine cards and I/O modules. The iDRAC FlexAddress feature supports
preservation of slot specific MAC address for iDRACs in a chassis. The chassisassigned MAC address is stored in CMC non
volatile memory and is sent to iDRAC during an iDRAC boot or when CMC FlexAddress is enabled.
