Ethernet Controller I210 —System Manageability
640
The MNGONLY is also configurable when using NC-SI using the Set Intel Filters — Manageability Only
Command (see Section 10.6.3.5.3).
All manageability filters are controlled by the MC only and not by the LAN device driver.
10.3.5 Possible Configurations
This section describes ways of using management filters. Actual usage may vary.
10.3.5.1 Dedicated MAC Packet Filtering
• Select one of the eight rules for dedicated MAC filtering.
• Load Host MAC address to one of the management MAC address filters and set the appropriate bit
in field 3:0 of the MDEF register.
• Set other bits to qualify which packets are allowed to pass through. For example:
— Load one or more management VLAN filters and set the appropriate bits in field 12:5 of the
MDEF register to qualify the relevant manageability VLANs.
— Set relevant bits in field 20:13 of the MDEF register to qualify with a match to one of the IP
addresses.
— Set any L3/L4 bits (bits 31:27 in the MDEF register and bits 23:16 in the MDEF_EXT register) to
filter using any set of L3/L4 filters.
10.3.5.2 Broadcast Packet Filtering
• Select one of the eight rules for broadcast filtering.
• Set bit 25 in the MDEF register of the decision rule to enforce broadcast filtering.
• Set other bits to qualify which broadcast packets are allowed to pass through. For example:
— Set bit 5 in the MDEF register to filter with the first manageability VLAN.
— Set relevant bits in field 20:13 of the MDEF register to qualify with a match to one of the IP
addresses.
— Set any L3/L4 bits (bits 31:27 in the MDEF register and bits 23:16 in the MDEF_EXT register) to
filter with any set of L3/L4 filters.
10.3.5.3 VLAN Packet Filtering
• Select one of the eight rules for VLAN filtering.
• Load one or more management VLAN filters and set the appropriate bits in field 12:5 of the MDEF
register to qualify the relevant manageability VLANs.
• Set other bits to qualify which VLAN packets are allowed to pass through. For example:
— Set any L3/L4 bits (bits 31:27 in the MDEF register and bits 23:16 in the MDEF_EXT register) to
filter using appropriate L3/L4 filter set.
10.3.5.4 IPv6 Filtering
IPv6 filtering is done using the following IPv6-specific filters:
