Intel^® 82598EB 10 GbE Controller - Sample Configurations
5.3.13 Sample Configurations
This section provides an overview and sample settings for commonly used filtering configurations.
Three examples are presented. The examples are in pseudo code format, with the name of the SMBus
command, followed by the parameters for that command and an explanation.
Here is a sample:
Receive Enable[00]
Utilizing the simple form of the Receive Enable command, this prevents any packets from reaching the
BMC by disabling filtering.
Example 5-1. Shared MAC, RMCP-Only Ports
This example will be the most basic configuration. The MAC address filtering will be shared with the
host operating system and only traffic directed the RMCP ports (26Fh & 298h) will be filtered. For this
simple example, the BMC must issue gratuitous ARPs because no filter will be enabled to pass ARP
requests to the BMC.
Pseudo Code
Step 1: Disable existing filtering
Receive Enable[00]
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: 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[0] value of 00000C00h:
Bit 10 [1]– port 298h
Bit 11 [1]– port 26Fh
Step 3: Enable Filtering
Receive Enable [45]
Using the simple form of the Receive Enable command:
Receive Enable Control 05h:
Bit 0 [1] – Enable Receiving of packets
Bit 2 [1] – Enable status reporting (such as link lost)
Bit 5:4 [00]– Notification method = SMB Alert
Bit 6 [1] - Reserved, must be set to 1
Bit 7 [0]– Use shared MAC
