iLO network connection considerations
• Only one of the Dedicated Network Port or Shared Network Port options can be enabled at a time
because iLO supports only one active NIC connection.
• By default, the iLO Shared Network Port uses port 1 on the server NIC. Depending on the server
configuration, this NIC might be a LOM or FlexibleLOM adapter. The port number corresponds to the
label on the NIC, which might be different from the numbering in the operating system.
If both the server and the NIC support port selection, the iLO firmware allows you to select a different
port number. If a port other than port 1 is selected for Shared Network Port use, and your server does
not support that configuration, iLO switches back to port 1 when it starts.
• Access to iLO through IPv6 is not currently supported when the Shared Network Port is enabled.
• On servers that do not have a Dedicated Network Port, the standard hardware configuration provides
iLO network connectivity only through the iLO Shared Network Port connection. On these servers, the
iLO firmware defaults to the Shared Network Port.
• Due to server auxiliary-power budget limitations, some 1Gb/s copper network adapters used for iLO
Shared Network Port functionality might run at 10/100 speed when the server is powered off. To avoid
this issue, Hewlett Packard Enterprise recommends configuring the switch that the iLO Shared
Network Port is connected to for auto-negotiation.
If the switch port that iLO is connected to is configured for 1Gb/s, some copper iLO Shared Network
Port adapters might lose connectivity when the server is powered off. Connectivity will return when the
server is powered back on.
• Disabling the iLO Shared Network Port does not completely disable the system NIC—server network
traffic can still pass through the NIC port. When the iLO Shared Network Port is disabled, any traffic
going to or originating from iLO will not pass through the Shared Network Port.
• If the Shared Network Port is enabled, you cannot modify the link state or duplex options. When using
Shared Network Port configurations, these settings must be managed in the operating system.
