Initial
Value
Description
MAC
3:0
0x0¹
MAC
Indicates if the MAC unicast filter registers (MMAH and MMAL) contain valid MAC
addresses. Bit 0 corresponds to filter 0, etc.
Reserved
7:4
0x0¹
Reserved
VLAN
15:8
0x0¹
VLAN
Indicates if the VLAN filter registers (MAVTV) contain valid VLAN tags. Bit 8
corresponds to filter 0, etc.
IPv4
19:16
0x0¹
IPv4
Indicates if the IPv4 address filters (MIPAF) contain valid IPv4 addresses. Bit 16
corresponds to IPv4 address 0. These bits apply only when IPv4 address filters are
enabled (MANC.EN_IPv4_FILTER=1b)
Reserved
23:20
0x0¹
Reserved
IPv6
27:24
0x0¹
IPv6
Indicates if the IPv6 address filter registers (MIPAF) contain valid IPv6 addresses. Bit
24 corresponds to address 0, etc. Bit 27 (filter 3) applies only when IPv4 address
filters are not enabled (MANC.EN_IPv4_FILTER=0b).
Reserved
31:28
0x0¹
Reserved
1. The initial values for this register can be loaded from the EEPROM by the management firmware after power-up reset or firmware
reset. The MFVAL register is written by the BMC and not accessible to the host for writing.
4.4.3.10.5 Management Control To Host Register – MANC2H (0x5860; RW)
The MANC2H register enables routing of manageability packets to the host based on the decision filter
that routed the packet to the manageability micro-controller. Each manageability decision filter (MDEF)
has a corresponding bit in the MANC2H register. When a manageability decision filter (MDEF) routes a
packet to manageability, it also routes the packet to the host if the corresponding MANC2HOST bit is set
and if the EN_MNG2HOST bit is set. The EN_MNG2HOST bit serves as a global enable for the MANC2H
bits.
Reset – The MANC2H register is cleared on Internal Power On Reset or LAN_PWR_GOOD, and firmware
reset.
Field
Host Enable
Bit(s)
7:0

Description
Host Enable
When set, indicates that packets routed by the manageability filters to
manageability are also sent to the host. Bit 0 corresponds to decision rule
0, etc.
