14.7.2 Management Flex UDP/TCP Ports - MFUTP
(5030h + 4*n [n=0..7]; R/W)
Where each 32-bit register (n=0,…,7) refers to two port filters (register 0 refers to ports 0 and 1,
register 2 refers to ports 2 and 3, etc.).
The MFUTP registers are written by the BMC and not accessible to the host for writing. The registers are
used to filter manageability packets as described the Intel® 82575 GbE Controller System
Manageability Interface Application Note.
Reset - The MFUTP registers are cleared on Internal_Power_On_Reset only. The initial values for this
register can be loaded from the EEPROM after a power-on reset.
Note: The MFUTP_even and MFUTP_odd fields should be written in network order.
14.7.3 Management Control Register - MANC (05820h;
R/W)
The MANC register is written by the BMC and is not accessible to the host for writing.

MFUTP_even 15:0 0b i Management flex UDP/TCP port.
MFUTP_odd 31:16 0b i + 1 Management flex UDP/TCP port.
Field Bits
Initial
Value
Description
Reserved 15:0 0b Reserved.
TCO_RESET 16 0b TCO Reset Occurred
Set to 1b on a TCO reset.
This bit is only reset by an Internal_Power_On_Reset.
RCV_TCO_EN 17 0b Receive TCO Packets Enabled
When this bit is set, it enables the receive flow from the wire to the
manageability block.
KEEP_PHY_LINK_UP 18 0b Block PHY Reset and Power State Changes
When this bit is set, the PHY reset and power state changes do not get to the
PHY. This bit cannot be written unless the Keep_PHY_Link_Up_En EEPROM bit is
set.
This bit is reset after an Internal_Power_On_Reset.
RCV_ALL 19 0b Receive All Enable
When set, all received packets that passed L2 filtering are directed to the
manageability block.
MCST_PASS_L2 20 0b Receive All Multicast
When set, all received multicast packets pass L2 filtering and can be directed to
the manageability block by one of the decision filters. Broadcast packets are not
forwarded by this bit.
EN_MNG2HOST 21 0b Enable MNG Packets to Host Memory
This bit enables the functionality of the MANC2H register. When set, the packets
that are specified in the MANC2H register are also sent to host memory as long
as they pass the manageability filters.
