Viewing Oc3/Stm-1 Atm Statistics - 3Com SuperStack II PathBuilder S330 Reference Manual

Viewing OC3/STM-1 ATM Statistics

To view OC3/STM-1 ATM statistics:
1 From the Performance Management menu, select [4] OC3/STM-1 UNI to open the
OC3/STM-1 Performance Management menu.
2 Select [2] ATM Statistics. ATM cell statistics are cell counts since the last counter
reset. On the OC3/STM-1 ATM Statistics screen, you can reset the counter by
entering [c].
The OC3/STM-1 ATM Statistics menu provides the following information:
Cells Received — The number of ATM cells received on the OC3/STM-1 since the
last user reset of this counter.
Cells transmitted — The number of ATM cells transmitted on the OC3/STM-1
since the last user reset of this counter.
Cells with Correctable HCS Error — The number of header check sequence
(HCS) errored cells encountered on the ATM interface.
Cells with Uncorrectable HCS Error — The number of idle/unassigned cells
encountered and dropped on the interface due to uncorrectable HCS errors.
Viewing DS3 Card You can view both performance statistics and ATM statistics for the DS3 UNI
Statistics module.
Viewing DS3 UNI Performance Statistics
To view DS3 UNI performance statistics:
1 From the Card Statistics menu, select [9] DS3 UNI to open the DS3 UNI
Performance Management menu. This menu is similar to the OC3/STM-1
Performance Management menu, shown earlier in Figure 162.
2 Select [1] DS3 UNI Performance Monitoring to open the DS3 Performance
Monitoring menu. The DS3 Performance Monitoring menu provides the following
information:
PES — The number of P-bit errored seconds (PESs) encountered by the DS3
interface
PSES — The number of P-bit severely errored seconds (PSESs) encountered by the
DS3 interface
SEFS — The number of severely errored framing seconds (SEFSs) encountered by
the DS3 interface
UAS — The number of unavailable seconds (UASs) encountered by the DS3
interface
LCV — The number of line coding violations (LCVs) encountered by the DS3
interface
PCV — The number of path coding violations (PCVs) encountered by the DS3
interface
LES — The number of line errored seconds (LESs) encountered by the DS3
interface
CCV — The number of C-bit coding violations (CCVs) encountered by the DS3
interface
