Network port configurations available to iLO

Possible configurations between the system network interface card NIC and the iLO based NIC
provide the user with choices to best suit individual system requirements (Figure 1). Choosing between
these options depends on knowing the benefits and cautions connected with each.

iLO common network

The iLO management port can be connected to the same network used by the server's main
10/100/1000 NIC to allow iLO control from anywhere on the network. Using a common network
simplifies installation, since all cables attach to the same network; however, iLO management
performance may be hindered by corporate network traffic.

iLO Shared Network Port

The iLO Shared Network Port feature on ProLiant servers allows system administrators to access iLO
using a network connection shared with the host operating system. SNP enables this shared
connection with a single cable. The ProLiant server Shared Network Port feature implements a
sideband connection between the main NIC and the iLO. This sideband connection maintains a
second (and separate) MAC address. This separate MAC address is assigned to iLO and allows iLO
to obtain a separate IP address. Thus, iLO and the server's NIC each have their own separate MAC
and IP addresses.
With iLO 2 only, shared network port provides a high-speed, full-featured connection to iLO. First
generation, iLO only servers with shared network port are limited-to a low-speed (text only) connection
to iLO when using the shared port.
When teaming host NICs, the iLO Shared Network Port can still be used, however iLO does not
benefit from teaming fault tolerance, nor does Shared Network Port prevent teaming, since iLO and
the host have separate MAC and IP addresses.
This feature reduces the number of network connections required to manage the server. The Shared
Network Port operates as miniature network switch, routing iLO information to the iLO network
interface and server operating system information to the operating system network interface. Using
this routing, where both ports are connected to the corporate network, allows fewer network
connections to the system. This approach enables access to iLO from anywhere on the network. One
