System Manageability—Ethernet Controller I210
717
This command causes the NC to filter packets that have passed due to the unicast filter (MAC address
filters, as specified in the DMTF NC-SI). Note that unicast filtering might be affected by other filters, as
specified in the DMTF NC-SI.
The filtering of these packets are done such that the MC might add a logical condition that a packet
must match, or it must be discarded.
Note: Packets that might have been blocked can still pass due to other decision filters.
In order to disable unicast packet reduction, the MC should set all reduction filters to 0b. Following such
a setting the NC must forward, to the MC, all packets that have passed the unicast filters (MAC address
filtering) as specified in the DMTF NC-SI.
The command shall overwrite any previously stored value.
Note: See Table 10-40 and Table 10-41 for description of the Unicast Extended Packet Reduction
format.
