System Manageability—Ethernet Controller I210
683
MDEF value of 10000000:
— Bit 28 [1] – ARP Requests
MDEF_EXT[0] value of 0000000h:
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 more details.
Step 6: Configure Manageability only
Update Manageability Filter Parameters [F, 0, 00000001]
Use the Update Manageability Filter Parameters command to update Manageability Only
(MNGONLY) (parameter Fh) so that port 298h and 26Fh would not be sent to the Host.
— Bit [0] - MDEF[0] is exclusive to the MC.
This allows ARP requests to be passed to both manageability and to the Host. Specified separate
MDEF filter for ARP requests. If ARP requests had been added to MDEF[0] and then MDEF[0]
specified in Management Only configuration then not only would RMCP traffic (ports 26Fh and
298h) be sent only to the MC, ARP requests would have also been sent to the MC only.
Step 7: Enable Filtering
Receive Enable [8D, AABBCCDD, 01020304, 00, 00, 00]
Using the advanced version Receive Enable command, the first parameter:
Receive Enable Control 8Dh:
— Bit 0 [1] – Enable Receiving of packets
— Bit 2 [1] – Enable status reporting (such as link lost)
— Bit 3 [1] – Enable Automatic ARP Responses
— Bit 5:4 [00] – Notification method = SMB Alert
— Bit 7 [1] - Use dedicated MAC
Second parameter is the MAC address (AABBCCDD).
Third Parameter is the IP address(01020304).
The last three parameters are zero when the notification method is SMB Alert.
The resulting MDEF filters are as follows:
