L2 P ROTOCOL (ATM–NET–ATM) > S TATUS
Displays all available ATM statistics (both overall and PVC-specific).
L2 P ROTOCOL (ATM–NET–ATM) > S TATUS > ATM S TATUS
Displays overall ATM link performance statistics. The following statistics are available:
L2 P
ROTOCOL
(ATM–NET–ATM) > S
TATUS
> ATM S
TATUS
> C
LEAR
S
TATS
Clears all ATM statistics contained in the ATM status field and returns all counters to 0.
QOS > P EAK C ELL R ATE
Defines the peak cell rate for the data PVC. This setting is normally used for Undefined Bit Rate
(UBR) connections and is calculated using the following equation:
Peak Cell Rate = Bit Rate / 424
The total of all peak cell rates for the ATM network connection must not exceed the line rate.
The range for this parameter is
0 to 3623 .
AP: T X C ELLS Number of cells transmitted over the ATM link.
AP: R X C ELLS Number of cells received over the ATM link.
AP: R X OAM C ELLS Number of Operation, Administration, and Maintenance
cells received on the ATM link. OAM cells provide
network fault indications, performance information, and
data and diagnostic functions.
AP: R ECEIVE C ELL
D ISCARDED
Number of cells received that are received and
discarded. An incrementing count in this field could
indicate a configuration problem with the ATM layer.
AP: R ECEIVE C ELL E RRORS Number of cells received that contain a Header Error
Control (HEC) error. The HEC is a CRC code located in
the last byte of the ATM cell header that’s used for
checking integrity.
AP: S YNC Indicates cell delineation at the ATM layer.
AP: O UT OF C ELL Indicates loss of cell delineation at the ATM layer.
AAL5: T RANSMIT F RAMES Number of ATM Adaptation Layer Type 5 frames
transmitted on the ATM link.
AAL5: R ECEIVE F RAMES Number of ATM Adaptation Layer Type 5 frames
received on the ATM link.
AAL5: T RANSMIT D ISCARDED
F RAMES
Number of ATM Adaptation Layer Type 5 transmitted
frames that were discarded before transmission.
AAL5: R ECEIVE E RRORS Number of ATM Adaptation Layer Type 5 frames that
were received and contained errors.
AAL5: R ECEIVE D ISCARDED
F RAMES
Number of ATM Adaptation Layer Type 5 frames that
were received but then discarded.
AAL5: N O ATM F RAMES Internal ADTRAN use only.
