10.6.3.14.7 Shared IP Enable Broadcast Filtering Command (Intel Command 0x25, Index =
0x6)
A new Shared IP Enable Broadcast Filtering is defined to allow the Management Controller to limit the
flow of ARP requests to those that contain a Target IP Address value that matches the Management
Controller IP Address.
This command should be used instead of the regular NC-SI Enable Broadcast Filtering command.
Note: Reception of a standard NC-SI Enable Broadcast Filtering command will enable the matching
bits in this command. Reception of a standard NC-SI Disable Broadcast Filter Command will
clear the settings in this command.
The format of an Shared IP Enable Broadcast Filtering command packet is specified in
Table 10-56.
