6.4.1.3 Proprietary Mellanox QoS Counters
Proprietary Mellanox QoS counter set consists of flow statistics per (VLAN) priority. Each QoS
policy is associated with a priority. The counter presents the priority's traffic, pause statistic.
Bad multicast received Number of bad multicast packet received.
Discarded UD packets Number of UD packets silently discarded on the receive queue due to lack
of receives descriptor.
Discarded UC packets Number of UC packets silently discarded on the receive queue due to lack
of receives descriptor.
CQ overflows Number of CQ overflows.
NOTE: this value is evaluated for the entire NIC since there are cases
where CQ might be associated with both ports (i.e. the value on all ports
is identical).
EQ overflows Number of EQ overflows.
NOTE: this value is evaluated for the entire NIC since there are cases
where EQ might be associated with both ports (i.e. the value on all ports
is identical).
Bad doorbells Number of bad DoorBells
Responder duplicate request
received (pending firmware
implementation).
Number of duplicate requests received when the local machine receives
inbound traffic.
Requester time out received
(pending firmware implementa-
tion).
Number of time out received when the local machine generates outbound
traffic.

Mellanox QoS Counters Description
Bytes/ Packets IN
Bytes Received The number of bytes received that are covered by this priority. The
counted bytes include framing characters (modulo 2^64).
Bytes Received/Sec The number of bytes received per second that are covered by this priority.
The counted bytes include framing characters.
Packets Received The number of packets received that are covered by this priority (modulo
2^64).
Packets Received/Sec The number of packets received per second that are covered by this prior-
ity.
