iDRAC networking can be assigned to its dedicated external network port or to share the main, onboard network port (LOM). This setting can be changed as desired by a system administrator.
Dedicated (Default): Uses the dedicated network interface port labeled “iDRAC”. This interface is not shared with the host operating system or application traffic. Dell iDRAC Security Best Practice is to use this setting. 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. Note, in modular or blade servers, the Dedicated option is displayed as “Chassis (Dedicated)”.
Shared LOM: The iDRAC shares the same physical connection on the Shared LOM but is separated from OS and application traffic using VLAN implementation.
