5.1.4 IMM2 dedicated versus shared ML2 Ethernet port
When configured as Dedicated, you are connecting to the network via the system
management port. As shown in Figure 5-3, the system management port is located from the
rear of the server to the right side of the USB ports.
Figure 5-3 Dedicated Gigabit IMM2 system management port
Using this port allows for easier separation of public and management network traffic.
Separating the traffic is done when you connect your public network port to switch ports that
belong to a public access virtual LAN (VLAN), and the management port is connected to a
switch port defined by a separate management VLAN.
When configured as
Shared, you are sharing network traffic on a ML2 Ethernet adapter,
which is the adapter slot closest to the rear fans, as shown in Figure 5-4. The default port
used on the ML2 adapter is port 1.

While this configuration eliminates a physical switch port and patch cable configuration, both
the media access control (MAC) address for the shared Ethernet port and the MAC address
for the IMM2 will address through this single network port. This situation means at least two
separate IP addresses for the same physical port, which prevents you from configuring the
ML2 adapter’s Ethernet port in a network team using 802.3ad load balancing if the particular
ML2 adapter that you are using supports this function.
