Item on Label Description Example/Additional Information
HOST (Base MAC) Represents the base MAC address for
high-speed data port 0
DPUs with more than one high-speed
port will use incremental (+1) MAC
addresses against the base HOST MAC on
the label.
For instance:
From the label - HOST: 94 6D AE F5 A1
CC
Port 0: 94 6D AE F5 A1 CC (same as
label)
Port 1: 94 6D AE F5 A1 CD (+1 from
base)
Port 2: 94 6D AE F5 A1 CE (+2 from base)
Port 3: 94 6D AE F5 A1 CF (+3 from base)
ECPF (Embedded CPU
Physical Function)
ECPF encompasses the embedded
Arm system responsible for managing
NIC resources and controlling the
data path.
Each physical high-speed port is
allocated one ECPF. The base ECPF MAC
is displayed on the label and is
associated with Port 0. The second port
(Port 1) receives base-ECPF+1 MAC
address and so forth, similar to HOST
MAC allocation pattern described
above.
MPF (Multi/Management
Physical Function)
For future use. N/A
OOB (Out-of-Band) OOB represents the MAC address of
the 1GbE out-of-band management
port of the DPU's embedded Arm
system.
Network traffic for the "OOB" (DPU
embedded Arm system) and "DPU BMC"
traverse through the 1GbE RJ-45
connector located on the front panel of
the DPU card.
DPU BMC (Baseboard
Management Controller)
Represents the MAC address for the
1GbE OOB management port of the
DPU BMC.
Note: The base MAC address for DPU
BMC is +1 from the OOB MAC address.
S/N (Serial Number) A unique serial number that
distinguishes your DPU from others.
The S/N is used for tracking and
support purposes.
