Example 5-3. Dedicated MAC & IP Address
This example provided the BMC with a dedicated MAC and IP address and allows it to receive ARP
requests. The BMC is then responsible for responding to ARP requests.
For demonstration purposes, the dedicated MAC address will be calculated by reading the System MAC
address and adding 1 do it, assume the System MAC is AABBCCDC. The IP address for this example will
be 1.2.3.4. For this example, the Receive Enable command is used to configure the MAC address filter.
In order for the BMC to be able to receive ARP Requests, it will need to specify a filter for this, and that
filter will need to be included in the Manageability To Host filtering so that the host OS may also receive
ARP Requests.
Pseudo Code
Step 1: Disable existing filtering
Receive Enable[40]
Utilizing the simple form of the Receive Enable command, this prevents any packets from reaching the
MC by disabling filtering:
