The content of the Shared IP Broadcast Packet Filter Settings field is specified in Table 10-63. Bit 4 has
been added to the standard Enable Broadcast Filtering Command Limit ARP Broadcast Packets to
Management Controller IP Address.
10.6.3.14.7.1Shared IP Enable Broadcast Filtering Response
The Network Controller shall, in the absence of a checksum error or identifier mismatch, always accept
the Shared IP Enable Broadcast Filtering command and send a response, using the format specified in
Table 10-58. Currently no command-specific reason codes are identified for this response.
10.6.3.14.8 Shared IP Enable Global Multicast Filtering Command (Intel Command 0x25,
Index = 0x7)
A new Shared IP Enable Global Multicast Filtering is defined to allow the Management Controller to
enable the forwarding of IEEE 802.1X Extensible Authentication Protocol over LAN (EAPOL) frames to
the Management Controller IP Address. IEEE 802.1X defines methods for port-based network access
control.
This command should be used instead of the regular NC-SI Enable Global Multicast Filtering command.
Note: Reception of a standard NC-SI Enable Global Multicast Filtering command will enable the
matching bits in this command. Reception of a standard NC-SI Disable Global Multicast Filter
Command will clear the settings in this command.

Limit ARP Broadcast
Packets to Management
Controller IP Address.
When bit 0 is set, this bit can be set to limit the flow of ARP packets to the
Management Controller as follows:
0x1 = Forward only ARP broadcast packets that are targeted at IP addresses
bound to the Management Controller.
0x0 = Forward all ARP broadcast packets to the Management Controller.
All the IPs set by the Set IP command before this command is given will be
included in forwarding.
This field is optional. If unsupported, the behavior for ARP packets will be set
according to bit 0 in this structure. The value shall be set to 0 if unsupported.
