Viewing Performance and ATM Statistics 193Cells dropped—The number of idle/unassigned cells encountered and droppedon the interface.Cells with HCS errors—The number of header check sequence (HCS) erroredcells encountered on the ATM interface.Viewing E3 CardStatisticsYou can view both performance statistics and ATM statistics for the E3 UNImodule.Viewing E3 UNI Performance StatisticsTo view E3 UNI performance statistics, follow these steps:1 From the Card Statistics menu, select [9] E3 UNI to open the E3 UNI PerformanceManagement menu. This menu is similar to the OC3/STM-1 PerformanceManagement menu, shown earlier in Figure 147.2 Select [1] E3 UNI Performance Monitoring to open the E3 PerformanceManagement menu. The E3 Performance Management menu provides thefollowing information:SEFS—The number of severely errored framing seconds (SEFSs) encountered bythe E3 interface.LCV—The number of line coding violations (LCVs) encountered by the E3interface.LES—The number of line errored seconds (LESs) encountered by the E3 interface.Viewing E3 UNI ATM StatisticsTo view E3 ATM statistics, follow these steps:1 From the Card Statistics menu, select [9] E3 UNI to open the E3 PerformanceManagement menu.2 From the E3 Performance Management menu, select [2] ATM Statistics. ATM cellstatistics are cell counts since the last counter reset. On the E3 ATM Statisticsscreen, you can reset the counter by entering [c].The E3 ATM Statistics menu provides the following information:Cells Received—The number of ATM cells received on the E3 since the last userreset of this counter.Cells transmitted—The number of ATM cells transmitted on the E3 since the lastuser reset of this counter.Cells dropped—The number of idle/unassigned cells encountered and droppedon the interface.Cells with HCS errors—The number of header check sequence (HCS) erroredcells encountered on the ATM interface.Viewing SIM CardStatisticsYou can view HDLC, Frame Relay, and ATM VC statistics for the serial port. To viewserial port statistics, follow these steps:1 From the Card Statistics menu, shown earlier in Figure 146, select [5] SIM. The SIMStatistics menu appears.2 Select [1] Port 1.3 Select the option corresponding to the type of statistics you want to view.
