This article provides information about pinging an iDRAC from within an Operating System when the iDRAC is being shared with the same LOM (LAN on Motherboard).
Users can configure a Dell EMC Poweredge iDRAC to operate on one or more of the LOM (LAN on Motherboard) ports. This is a common practice to limit the number of physical switch ports required in the network environment or provide physical redundancy to the iDRAC. When this network configuration is leveraged, an end-user may notice that the Host Operating System cannot ping or connect to its own iDRAC IP Address on the shared switch port.
This behavior is a Layer-2 networking limitation when both the Host Operating System and iDRAC are using the same VLAN (Virtual Local Area Network). When a broadcast packet is sent from the Host Operating System, the broadcast excludes the source switch port. In this scenario, the iDRAC will not receive the broadcast request.
In order to resolve this issue, Dell EMC Engineering recommends that Host Operating System and iDRAC exist on separate VLANs. In order to achieve this configuration, there are some considerations that need to be taken into account:
