DGS-1520 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide ifInErrors Received Error Packet Counter. Incremented for received packets which contained errors preventing them from being deliverable to a higher-layer protocol. The counter is the sum of dot3StatsAlignmentErrors, dot3StatsFCSErrors, dot3StatsFrameTooLongs, dot3StatsInternalMacReceiveErrors, dot3StatsSymbolErrors, undersize, fragment, oversize, and jabber error. ifOutErrors Transmit Error Packet Counter. Incremented for outbound packets which could not be transmitted because of errors. The counter is the sum of dot3StatsSQETestErrors, dot3StatsLateCollisions, dot3StatsExcessiveCollisions, dot3StatsInternalMacTransmitErrors and dot3StatsCarrierSenseErrors. ifInDiscards Receive Discards Packet Counter. Incremented for packets received which are dropped due to any condition. Such as MTU drop, Buffer Full Drop, ACL Drop, Multicast Drop, VLAN Ingress Drop, Invalid IPv6, STP Drop, Storm and FDB Discard, and etc. ifOutDiscards Transmit Discards Packet Counter. Incremented for packets transmitted which are dropped due to any condition. Such as excessive transit delay discards, HOL drop, STP drop, MTU drop, VLAN drop, and etc. ifInUnknownProtos Receive Discards Unknown and Unsupported protocol Counter .Incremented for packets received, which were discarded because of an unknown or unsupported protocol. txDelayExceededDiscards Transmit Multiple Deferral Packet Counter. Incremented for packets transmitted which are discarded due to excessive transit delay. txCRC Transmit FCS Error Packet Counter. Incremented for each frame transmitted which does not pass the FCS check. txSTPDropPkts Transmit STP Drop Packet Counter. Incremented for packets dropped because the Spanning Tree State of the egress port was not in the forwarding state. txHOLDropPkts Transmit HOL Drop Packet Counter. Incremented for each packet dropped due to Head Of Line blocking. dot3StatsAlignmentErrors Receive Alignment Error Frame Counter. Incremented for each frame received which are not an integral number of octets in length and does not pass the FCS check. dot3StatsFCSErrors Receive FCS Error Frame Counter. Incremented for each packet received which is an integral number of octets in length but do not pass the FCS check. dot3StatsSingleColFrame s Transmit Single Collision Frame Counter. 10/100 mode only-incremented for each frame transmitted which experienced exactly one collision during transmission. dot3StatsMultiColFrames Transmit Multiple Collision Frame Counter. 10/100 mode only-incremented for each frame successfully transmitted for which transmission is inhibited by more than one collision. dot3StatsSQETestErrors SQET Test Error Counter. Incremented for times that the SQE TEST ERROR message is generated by the PLS sublayer for a particular interface. The SQE TEST ERROR message is defined in section 7.2.2.2.4 of ANSI/IEEE 802.3-1985 and its generation is described in section 7.2.4.6 of the same document. Note: This counter does not increment at speeds greater than 10 Mb/s or in fullduplex mode. dot3StatsDeferredTransmi Transmit Single Deferral Frame Counter. 10/100 mode only-incremented for ssions each frame which was deferred on its first transmission attempt and did not experience any subsequence collisions during transmission. dot3StatsLateCollisions Transmit Late Collision Frame Counter. 10/100 mode only-incremented for each frame transmitted which experienced a late collision during a transmission attempt. dot3StatsExcessiveCollisi Transmit Excessive Collision Frame Counter. 10/100 mode only-incremented ons for each frame transmitted for which transmission fails due to excessive collisions. 435
