L2 PROTOCOL (T1 ATM–T1–ATM) > STATUS > ATM STATUS
Displays overall ATM link performance statistics. The following statistics are available:
L2 PROTOCOL (T1 ATM–T1–ATM) > STATUS > ATM STATUS > CLEAR STATS
Clears all ATM statistics contained in the ATM status field and returns all counters to 0.
L2 PROTOCOL (T1 ATM–T1–ATM) > STATUS > PVC STATUS
View the ATM PVC statistics from this menu.
L2 PROTOCOL (T1 ATM–T1–ATM) > STATUS > PVC STATUS > NUM
Displays the index number in the PVC Status menu.
AP: TX CELLS Number of cells transmitted over the ATM link.
AP: R
X CELLS Number of cells received over the ATM link.
AP: R
X OAM CELLS 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 CELL
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 CELL ERRORS 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 CELL Indicates loss of cell delineation at the ATM layer.
AAL5: T
RANSMIT FRAMES Number of ATM Adaptation Layer Type 5 frames
transmitted on the ATM link.
AAL5: R
ECEIVE FRAMES Number of ATM Adaptation Layer Type 5 frames
received on the ATM link.
AAL5: T
RANSMIT DISCARDED
F
RAMES
Number of ATM Adaptation Layer Type 5 transmitted
frames that were discarded before transmission.
AAL5: R
ECEIVE ERRORS Number of ATM Adaptation Layer Type 5 frames that
were received and contained errors.
AAL5: R
ECEIVE DISCARDED
F
RAMES
Number of ATM Adaptation Layer Type 5 frames that
were received but then discarded.
