Ethernet Controller I210 —System Manageability
680
If case of error the following answers may be returned
This response is by the I210, on read common filter command when the data that should have been
read is not ready. This parameter has no data. The MC should retry the read transaction.
This value is also returned if the byte count is illegal or if the read command is not preceded by a write
command.
10.5.10 Example Configuration Steps
This section provides sample configuration settings for common 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.
10.5.10.1 Example 1 - Shared MAC, RMCP Only Ports
This example is the most basic configuration. The MAC address filtering is shared with the Host
operating system and only traffic directed the RMCP ports (26Fh & 298h) is filtered. For this example,
the MC must issue gratuitous ARPs because no filter is enabled to pass ARP requests to the MC.
10.5.10.1.1 Example 1 Pseudo Code
Step 1: Disable existing filtering
Receive Enable[00]
Utilizi
ng the simple form of the Receive Enable command, this prevents any packets from
reaching the MC by disabling filtering:
Receive Enable Control 00h:
— Bit 0 [0] – Disable Receiving of packets
Step 2: Configure MDEF[0]
