8.20 Manageability Statistics
This section describes a set of statistics counters used by the NC-SI interface and are not accessible to
the host driver.
8.20.1 MC Management Receive Packets Dropped Count - BMRPDC
(0x4140; RC)
This register counts the total number of packets received that pass the management filters as
described in Section 10.3, that are dropped because the management receive FIFO is full. Management
packets include any packet directed to the manageability console (for example, MC and ARP packets).
This register is available to the firmware only.
8.20.2 MC Management Transmit Packets Dropped Count - BMTPDC
(0x8FDC; RC)
This register counts the total number of packets received from the Out-of-Band Management interface,
that are dropped because the management transmit FIFO is full or if the relevant NC-SI channel is
disabled. This counter increases only if the packet is not sent to any destination (host or network).
Note: This register is available to firmware only and is shared for MC Tx traffic destined to the port.
8.20.3 MC Management Packets Transmitted Count - BMNGPTC
(0x4144; RC)
This register counts the total number of transmitted packets originating from the manageability path.
This counter increases once if the packet is sent to any destination (host or network).
This register is available to the firmware only.
