10.6.3.9 System MAC Address
10.6.3.9.1 Get System MAC Address Command (Intel Command 0x06)
In order to support a system configuration that requires the NC to hold the MAC address for the MC
(such as shared MAC address mode), the following command is provided to enable the MC to query the
NC for a valid MAC address.
The NC must return the system MAC addresses. The MC should use the returned MAC addressing as a
shared MAC address by setting it using the Set MAC Address command as defined in NC-SI 1.0.
It is also recommended that the MC use packet reduction and Manageability-to-Host command to set
the proper filtering method.
