10.5.9.1.6 Update Management Receive Filter Parameters
This command is used to set the manageability receive filters parameters. The command is 0xCC. The
first data byte is the parameter number and the data that follows (length and content) are parameter
specific as listed in management RCV filter parameters.
If the parameter that the MC sets is not supported by the I210, then the I210 does not NACK the
transaction. After the transaction ends, the I210 discards the data and asserts a transaction abort
status.
The update management RCV receive filter parameters command format is as follows:
Table 10-12 lists the different parameters and their content.

Table 10-12. Management Receive Filter Parameters
Parameter Number Parameter Data
Filters Enables 0x1
Defines the generic filters configuration. The structure of this parameter is four bytes
as the Manageability Control (MANC) register.
Note: The general filter enable is in the Receive Enable command that enables
receive filtering.
MNGONLY configuration 0xF
This parameter defines which of the packets types identified as manageability
packets in the receive path will never be directed to the Host memory.
Data 2:5: MNGONLY register bytes - Data 2 is the MSB
Flex Filter 0 Enable Mask and
Length
0x10
Flex Filter 0 Mask.
Data 17:2 = Mask. Bit 0 in data 2 is the first bit of the mask.
Data 19:18 = Reserved. Should be set to 00b.
Date 20 = Flexible filter length.
Flex Filter 0 Data 0x11
Data 2 — Group of flex filter’s bytes:
0x0 = bytes 0-29
0x1 = bytes 30-59
0x2 = bytes 60-89
0x3 = bytes 90-119
0x4 = bytes 120-127
Data 3:32 = Flex filter data bytes. Data 3 is LSB.
Group's length is not a mandatory 30 bytes; it might vary according to filter's length
and must NOT be padded by zeros.
Decision Filters 0x61 This command is obsolete. Please use 0x68 instead
VLAN Filters 0x62
Three bytes are required to load the VLAN tag filters.
Data 2: VLAN filter number.
Data 3: MSB of VLAN filter.
Data 4: LSB of VLAN filter.
