NOTE: This feature is available with iDRAC Express and iDRAC Enterprise licenses.
To view the OS information, make sure that:
• You have Login privilege.
• iDRAC Service Module is installed and running on the host operating system.
• OS Information option is enabled in the Overview → Server → Service Module page.
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 Overview → 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 Command Line Reference Guide available at dell.com/esmmanuals.
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 Dell Chassis Management Controller User Guide available at dell.com/support/manuals. 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 server–assigned MAC addresses with chassis–assigned 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
