CBR Performance Monitoring Statistics
The CBR Performance Monitoring screens display the following statistics for the
CBR T1-DSX/E1 ports:
ES
— The number of errored seconds (ESs) encountered by the CBR T1-DSX/E1
interface
SES
— The number of severely-errored seconds (SESs) encountered by the CBR
T1-DSX/E1 interface
SEFS
— The number of severely errored framing seconds (SEFSs) encountered by
the CBR T1-DSX/E1 interface
UAS
— The number of unavailable seconds (UASs) encountered by the CBR
T1-DSX/E1 interface
CSS
— The number of controlled slip seconds (CSSs) encountered by the CBR
T1-DSX/E1 interface
PCV
— The number of path coding violations (PCVs) encountered by the CBR
T1-DSX/E1 interface
LES
— The number of line errored seconds (LESs) encountered by the CBR
T1-DSX/E1 interface
BES
— The number of bursty errored seconds (BESs) encountered by the CBR
T1-DSX/E1 interface
DM
— The number of degraded minutes (DMs) encountered by the CBR
T1-DSX/E1 interface
LCV
— The number of line coding violations (LCVs) encountered by the CBR
T1-DSX/E1 interface
CBR ATM Statistics
CBR ATM cell statistics are cell counts since the last counter reset. On the CBR
ATM Statistics screen, you can reset the counter by entering
c
. ATM statistics are
displayed as a list rather than a table. The CBR T1-DSX and CBR E1 ATM Statistics
screens display the following statistics:
CBR virtual circuits must be present in the database in order to view these
statistics.
Total Cells Received
— The total number of cells received over the virtual circuit.
Total Cells Transmitted
— The total number of cells transmitted over the virtual
circuit.
Total Cell Pointer Errors
— The number of cells dropped due to structure pointer
mismatches.
Total Cells Lost
— The difference between the number of cells transmitted and
the number of cells received.
Total Number of Buffer Underflows
— The number of buffer underflows over
the virtual circuit.
Total Number of Buffer Overflows
— The number of buffer overflows over the
virtual circuit.
Total out of Sequence Errors
— The number of cells received with
out-of-sequence number mismatch.
