Intel^® 82598EB 10 GbE Controller - Sample Configurations
Receive Enable[40]
Utilizing the simple form of the Receive Enable command, this prevents any packets from reaching the
MC by disabling filtering:
Receive Enable Control 40h:
Bit 0 [0]– Disable Receiving of packets
Bit 6 [1] - Reserved, must be set to 1
Step 2: Read System MAC Address
Get System MAC Address []
Reads the System MAC address. Assume returned AABBCCDDED for this example.
Step 3: Enable MNG2Host & XSUM Filters
Update Manageability Filter Parameters [01, 00A00000]
Use the Update Manageability Filter Parameters command to update Filters Enable settings (parameter
1). This set the Manageability Control (MANC) Register.
MANC Register 00A00000h:
Bit 21 [1]- MNG2Host Filter Enable
Bit 23 [1]– XSUM Filter enable
Some of the following configuration steps manipulate the MANC register indirectly, this command sets
all bits except XSUM to 0. It is important to either do this step before the others, or to read the value
of the MANC and then write it back with only bit 32 changed. Also note that the XSUM enable bit may
differ between Ethernet Controllers, refer to product specific documentation.
Step 4: Configure MDEF[0]
Update Manageability Filter Parameters [61, 0, 00000C00]
Use the Update Manageability Filter Parameters command to update Decision Filters (MDEF)
(parameter 61h). This will update MDEF[0], as indicated by the 2^nd parameter (0).
MDEF value of 00000C00h:
Bit 10 [1]– port 298h
Bit 11 [1]– port 26Fh
Step 5: Configure MDEF[1]
Update Manageability Filter Parameters [61, 1, 00000080]
Use the Update Manageability Filter Parameters command to update Decision Filters (MDEF)
(parameter 61h). This will update MDEF[1], as indicated by the 2^nd parameter (1).
MDEF value of 00000080:
Bit 7 [7]– ARP Requests
When Enabling Automatic ARP responses, the ARP requests still go into the manageability filtering
system and as such need to be designated as also needing to be sent to the host. For this reason a
separate MDEF is created with only ARP request filtering enabled.
Refer to the next step for details.
Step 6: Configure the Management to Host Filter
Update Manageability Filter Parameters [0A, 00000002]
Use the Update Manageability Filter Parameters command to update the Management Control to Host
(MANC2H) Register.
