6.4.1.2 Proprietary Mellanox Adapter Diagnostics Counters
Proprietary Mellanox adapter diagnostics counter set consists of the NIC diagnostics. These
counters collect information from ConnectX®-3 and ConnectX®-3 Pro firmware flows.
ERRORS, DROP, AND MISC. INDICATIONS
Packets Outbound Errors Shows the number of outbound packets that could not be transmitted
because of errors.
Packets Outbound Discarded Shows the number of outbound packets to be discarded even though no
errors had been detected to prevent transmission. One possible reason for
discarding packets could be to free up buffer space.
Packets Received Errors Shows the number of inbound packets that contained errors preventing
them from being deliverable to a higher-layer protocol.
Packets Received with Frame
Length Error
Shows the number of inbound packets that contained error where the
frame has length error. Packets received with frame length error are a sub-
set of packets received errors.
Packets Received with Symbol
Error
Shows the number of inbound packets that contained symbol error or an
invalid block. Packets received with symbol error are a subset of packets
received errors.
Packets Received with Bad CRC
Error
Shows the number of inbound packets that contained bad CRC error.
Packets received with bad CRC error are a subset of packets received
errors.
Packets Received Discarded Shows the number of inbound packets that were chosen to be discarded
even though no errors had been detected to prevent their being deliverable
to a higher-layer protocol. One possible reason for discarding such a
packet could be to free up buffer space.

Description
Requester length errors Number of local length errors when the local machine generates outbound
traffic.
Responder length errors Number of local length errors when the local machine receives inbound
traffic.
Requester QP operation errors Number of local QP operation errors when the local machine generates
outbound traffic.
Responder QP operation errors Number of local QP operation errors when the local machine receives
inbound traffic.
Requester protection errors Number of local protection errors when the local machine generates out-
bound traffic.
