Description The sum of single collision frames discarded, multiple collision frames discarded, and excessive frames discarded. The total number of Aged packets. A count of the number of successfully transmitted frames on a particular interface for which transmission is inhibited by exactly one collision. A count of the number of successfully transmitted frames on a particular interface for which transmission is inhibited by more than one collision. A count of frames for which transmission on a particular interface fails due to excessive collisions. Total number of collisions that occur after 512 bit collision window has passed. The number of frames discarded on egress for this port due to egress filtering being enabled. Loss of the carrier detection occurs when the carrier signal of the hardware is undetectable. It could be because the carrier signal was not present or was present but could not be detected. Each such event causes this counter to increase. Number of STP BPDUs received at the selected port. Number of STP BPDUs transmitted from the selected port. Number of RSTP BPDUs received at the selected port. Number of RSTP BPDUs transmitted from the selected port. Number of MSTP BPDUs received at the selected port. Number of MSTP BPDUs transmitted from the selected port. A count of MAC Control frames transmitted on this interface with an opcode indicating the PAUSE operation. This counter does not increment when the interface is operating in half-duplex mode. The count of GVRP PDUs received in the GARP layer. The count of GVRP PDUs transmitted from the GARP layer. The number of times attempted GVRP registrations could not be completed. The count of GMRP PDUs received from the GARP layer. The count of GMRP PDUs transmitted from the GARP layer. The number of times attempted GMRP registrations could not be completed. The elapsed time, in days, hours, minutes, and seconds since the statistics for this port were last cleared. • Click Clear Counters to clear all the counters. This resets all statistics for this port to the default values. • Click Clear All Counters to clear all the counters for all ports on the switch. The button resets all statistics for all ports to default values. • Click Refresh to refresh the data on the screen and display the most current statistics. PORT SUMMARY STATISTICS The Port Summary Statistics page shows a summary of per-port traffic statistics on the switch. Document 34CSFP6XXUWS-SWUM100-D7 Viewing System Statistics Page 137
