Integrated Dell Remote Access Controller 9 User's Guide

Port-based Network Access Control (IEEE 802.1x)

Starting from iDRAC release 6.10.00.00, iDRAC provides Port-based network access control (IEEE802.1x). It provides a secured authentication mechanism to devices wishing to attach to a LAN.

This feature requires iDRAC Datacenter license.

You can access this feature using iDRAC GUI by navigating to- iDRAC Settings > Connectivity > Network > Advanced Network Settings > 802.1x Security. You can enable or disable the option using the drop-down. The feature is enabled by default.

NOTE:The effect of 802.1x does not work in Shared LOM mode with VLAN enabled.

Port-based Network Access Control has three ways of configuring the authentication certificates:

  • Default IDevID— This is the default iDRAC certificate installed in the factory.
  • Custom Signing LDevID— Using this option, you are able to define a Certificate Signing Request (CSR) which is signed by the uploaded LDEVID Signing Certificate.
  • Custom LDevID— Using this option, you are able to upload a custom certificate of choice.

There is option to enable or disable Authentication Server Certificate, for providing the necessary information to validate the certificate. This option is disabled by default.

NOTE:
  • This feature is disabled by default in modular servers.
  • Any change in 802.1x configuration, including certificate uploads and enabling/disabling settings, takes effect on the next iDRAC boot.
  • Switching iDRAC network between 802.1x enabled switch & Non 802.1x switch needs idrac reboot.
  • If the ports on the Ethernet Switch which are connected to the server's LOM ports are enabled for 802.1X security, then all downstream devices on those ports need to be enabled for 8021.X security. This means the host is impacted if it has not been enabled for 802.1X security.
