14.7.7 Manageability IP Address Filter - MIPAF
(0x58B0-0x58EC; RW)
The Manageability IP Address Filter register stores IP addresses for manageability filtering. The MIPAF
register can be used in two configurations, depending on the value of the MANC. EN_IPv4_FILTER bit:
• EN_IPv4_FILTER = 0b: the last 128 bits of the register store a single IPv6 address (IPV6ADDR3)
• EN_IPv4_FILTER = 1b: the last 128 bits of the register store four IPv4 addresses (IPV4ADDR[3:0])
The initial values for these registers can be loaded from the EEPROM after power-up reset. The
registers are written by the BMC and not accessible to the host for writing.
Reset - The registers are cleared on Internal_Power_On_Reset only.
The MIPAF registers value should be configured to the register in host order.
EN_IPv4_FILTER = 0b:
Multicast

60b
1
Multicast
Controls the inclusion of Multicast address filtering in the manageability filter decision
(AND section). Broadcast packets are not included by this bit. The packet must pass some
L2 filtering to be included by this bit – either by the MANC.MCST_PASS_L2 or by some
dedicated MAC address.
ARP Request 7 0b
1
ARP Request
Controls the inclusion of ARP Request filtering in the manageability filter decision (OR
section).
ARP

ARP Response
Controls the inclusion of ARP Response filtering in the manageability filter decision (OR
section).
Neighbor

Neighbor Discovery
Controls the inclusion of Neighbor Discovery filtering in the manageability filter decision
(OR section). The neighbor types accepted by this filter are types 86h, 87h, 88h & 89h
Port 0x298 10 0b

Port 0x298
Controls the inclusion of Port 0x298 filtering in the manageability filter decision (OR
section).
Port 0x26F 11 0b
1
Port 0x26F
Controls the inclusion of Port 0x26F filtering in the manageability filter decision (OR
section).
Flex port 27:12 00h

Flex port
Controls the inclusion of Flex port filtering in the manageability filter decision (OR
section). Bit 12 corresponds to flex port 0, etc.
Flex TCO 31:28 00h
1
Flex TCO
Controls the inclusion of Flex TCO filtering in the manageability filter decision (OR
section). Bit 28 corresponds to Flex TCO filter 0, etc.
