Table 7-1 Port Statistics Display Field Descriptions
Field

Description
|
InOctets
|
Cumulative number of octets that arrived at the port, including framing characters.
|
InUcastPkts
|
Cumulative number of incoming packets destined for a single port.
|
InMulticastPkts
|
Cumulative number of incoming packets destined for the ports of a multicast group.
|
InBroadcastPkts
|
Cumulative number of incoming packets destined for all ports on the fabric.

|
Cumulative number of inbound packets that the port discarded for a reason other than a packet error (such as the lack of buffer space).
|
InErrors
|
Number of inbound packets with errors that the port discarded.
|
InUnknownProtos
|
For packet-oriented interfaces, the number of packets received through the interface that were discarded because of an unknown or unsupported protocol. For character-oriented or fixed-length interfaces that support protocol multiplexing, the number of transmission units received through the interface that were discarded because of an unknown or unsupported protocol. For any interface that does not support protocol multiplexing, this counter is always 0.
|
OutOctets
|
Total number of octets transmitted out of the interface including framing characters.
|
OutUcastPkts
|
Total number of packets that higher-level protocols requested be transmitted and which were not addressed to a multicast or broadcast address at this sublayer, including those packets that were discarded or not sent.
|
OutMulticastPkts
|
Total number of packets that higher-level protocols requested be transmitted, and which were addressed to a multicast address at this sublayer, including those packets that were discarded or not sent. For a MAC layer protocol, includes both Group and Functional addresses.
|
OutBroadcastPkts

Total number of packets that higher-level protocols requested to be transmitted and that were addressed to a broadcast address at this sublayer, including those packets that were discarded or not sent.
|
OutDiscards
|
Number of outbound packets that were chosen to be discarded even though no errors had been detected to prevent their being transmitted. One possible reason for discarding such a packet could be to free-up buffer space.
|
OutErrors
|
For packet-oriented interfaces, the number of outbound packets that could not be transmitted because of errors. For character-oriented or fixed-length interfaces, the number of outbound transmission units that could not be transmitted because of errors.

Table 7-4 Ethernet Statistics Field Descriptions
Field
|
Description
|
SingleCollisionFrames
|
Count of successfully transmitted frames on a particular interface for which transmission is inhibited by exactly one collision. A frame that is counted by an instance of this object is also counted by the corresponding instance of the out-ucast-pkts, out-multicast-pkts, or out-broadcast-pkts, and is not counted by the corresponding instance of the multiple-collision-frames object. This counter does not increment when the interface is operating in full-duplex mode.
|
MultipleCollisionFrames
|
Count of successfully transmitted frames on a particular interface for which transmission is inhibited by more than one collision. A frame that is counted by an instance of this object is also counted by the corresponding instance of the out-ucast-pkts, out-multicast-pkts, or out-broadcast-pkts, and is not counted by the corresponding instance of the single-collision-frames object. This counter does not increment when the interface is operating in full-duplex mode.
|
AlignmentErrors
|
Count of frames received on a particular interface that are not an integral number of octets in length and do not pass the FCS check. The count represented by an instance of this object is incremented when the alignmentError status is returned by the MAC service to the Logical Link Control (LLC) or other MAC user. Received frames for which multiple obtained error conditions are counted exclusively according to the error status presented to the LLC. This counter does not increment for 8-bit wide group encoding schemes.
|
FCSErrors
|
Count of frames received on a particular interface that are an integral number of octets in length but do not pass the FCS check. This count does not include frames received with frame-too-long or frame-too-short errors. The count is incremented when the frameCheckError status is returned by the MAC service to the LLC (or other MAC user). Received frames for which multiple error conditions obtained are counted exclusively according to the error status presented to the LLC.
Coding errors detected by the physical layer for speeds above 10 Mbps will cause the frame to fail the FCS check.
|
SQETestErrors
|
Count of times that the SQE TEST ERROR message is generated by the PLS sub layer for a particular interface. The SQE TEST ERROR is set in accordance with the rules for verification of the SQE detection mechanism in the PLS Carrier Sense Function, as described in IEEE 802.3, 1998 Edition, section 7.2.4.6. This counter does not increment on interfaces operating at speeds greater than 10 Mbps or on interfaces operating in full-duplex mode.
|
DeferredTransmissions
|
Count of frames for which the first transmission attempt on a particular interface is delayed because the medium is busy. The count represented by an instance of this object does not include frames involved in collisions. This counter does not increment when the interface is operating in full-duplex mode.
|
LateCollisions
|
Number of times that a collision is detected on an interface later than one Ethernet slot-time unit into transmission of a packet. A late collision included in this count is also considered to be a generic collision for purposes of other collision-related statistics. This counter does not increment when the interface is operating in full-duplex mode.
|
ExcessiveCollisions
|
Count of frames for which transmission on an interface fails due to excessive collisions. This counter does not increment when the interface is operating in full-duplex mode.
|
InternalMacTransmitErrors
|
Count of frames for which transmission on an interface fails due to an internal MAC sub layer transmit error. A frame is counted only if it is not counted by the corresponding instance of the late-collisions object, the excessive-collisions object, or the carrier-sense-errors object. The precise meaning of this count is implementation-specific. This object may represent a count of transmission errors on a particular interface that is not otherwise counted.
|
CarrierSenseErrors
|
Number of times that the carrier sense condition was lost or never asserted when attempting to transmit a frame on an interface. This count is incremented, at most, once per transmission attempt, even if the carrier sense condition fluctuates during a transmission attempt. This counter does not increment when the interface is operating in full-duplex mode.
|
FrameTooLongs
|
Count of frames received on an interface that exceed the maximum permitted frame size. The count is incremented when the frame-too-longs status is returned by the MAC service to the LLC (or other MAC user). Received frames for which multiple error conditions obtained are counted exclusively according to the error status presented to the LLC.
|
InternalMacReceiveErrors
|
Count of frames for which reception on an interface fails due to an internal MAC sub layer receive error. A frame is counted only if it is not counted by the corresponding instance of the frame-too-longs, alignment-errors, or fcs-errors object. The precise meaning of this count is implementation-specific. An instance of this object may represent a count of receive errors on a particular interface that is not otherwise counted.
|
Graphing Port Statistics
Element Manager provides utilities that create line charts, area charts, bar charts, and pie charts to visually represent port statistics.
