8.22.6 Management Only Traffic Register - MNGONLY (0x5864; RW)
The MNGONLY register enables exclusive filtering of a certain type of traffic to the MC. Exclusive
filtering enables the MC to define certain packets that are forwarded to the MC but not to the host. The
packets are not be forwarded to the host even if they pass the host L2 filtering process.
Each manageability decision filter (MDEF and MDEF_EXT) has a corresponding bit in the MNGONLY
register. When a manageability decision filter (MDEF and MDEF_EXT) forwards a packet to
manageability, it can also block the packet from being forwarded to the host if the corresponding
MNGONLY bit is set.
8.22.7 Manageability Decision Filters - MDEF (0x5890 + 4*n [n=0...7];
RW)
Where “n” is the decision filter.
EN_BMC2NET (RO) 29 1b
1
Enable MC to network and network to MC traffic.
0b = The MC cannot communicate with the network.
1b = The MC can communicate with the network.
When cleared, the MC traffic is not forwarded to the network and the network
traffic is not forwarded to the MC even if the decision filters indicates it should.
This bit does not impact the host-to-MC traffic.
Note:
1. Initial value loaded according to value of Port n traffic types field in Flash
(refer to Section 6.7.7.2).
2.
MPROXYE (RO) 30 0b
1
Management Proxying Enable.
When set to 1b, proxying of packets is enabled when the device is in a D3 low
power state.
0b = Manageability does not support proxying.
1b = Manageability supports proxying.
Note: Proxy information and requirements are passed by the software device
driver to firmware via the shared RAM host interface (refer to
Section 10.8, Section 8.23 and Section 10.8.2.4.5).
Note: Proxying traffic from and to firmware is not affected by the
MANC.RCV_TCO_EN bit or the MANC.EN_BMC2NET bit.

Description
Exclusive to
MNG
7:0 0x0
Exclusive to MNG.
When set, indicates that packets forwarded by the manageability filters to
manageability are not sent to the host. Bits 0...7 correspond to decision
rules defined in registers MDEF[0...7] and MDEF_EXT[0...7].
Reserved 31:8 0x0
Reserved.
Write 0x0, ignore on read.
