adstat - show ATM device driver statistics
adstat [ -poa045d ] device [ interval ]
The adstat program displays Physical layer, ATM layer, ATM Adaptation Layer
(AAL), and device-specific counters gathered by the ATM device driver.
The device argument is the name of the ATM device, for example fatm1. If
interval is specified, adstat summarizes activity during each interval second
period. Only a single layer may be selected when specifying an
interval. The fields of adstat's display are as follows:
Output Cells Number of cells transmitted by the ATM device driver.
Input Cells Number of cells received by the ATM device driver.
- Framing
- Numbers of cells received with bad framing.
- Hdr-CRC
- Number of cells received with bad header CRC.
- VPI-OOR
- Number of cells received with out of range VPI.
- VPI-NoC
- Number of cells received for a disconnected VP.
- VCI-OOR
- Number of cells received with out of range VCI.
- VCI-NoC
- Number of cells received for a disconnected VC.
- Drops
- Number of cells dropped due to lack of buffer space or queue
overflow.
- Congestn
- Number of AAL 5 CS-PDUs dropped due to cells lost or gained
as a result of network congestion.
- CS-PDUs
- Number of PDUs to (input) or from (output) CS-sublayer.
- CSProto
- Number of CS-PDUs received with protocol errors.
- Pay-CRC
- Number of cells (AAL 4) or CS-PDUs (AAL 5) received with bad
payload CRC.
- SARProto
- Number of cells received with SAR protocol errors.
Section BIP Number of PMD section layer BIP errors detected in STS
stream.
- Path BIP
- Number of PMD path layer BIP errors detected in STS stream.
- Line BIP
- Number of PMD line layer BIP errors detected in STS stream.
- Line FEBE
- Number of PMD line layer FEBE errors detected in STS stream.
- Path FEBE
- Number of PMD path layer FEBE errors detected in STS stream.
- Corr HCS
- Number of cells received with correctable HCS.
Uncorr HCS Number of cells received with uncorrectable HCS.
Buffer Allocation Failures
Number of times a buffer of the required size and type was
unavailable. The type and size of small and large buffers
is platform dependent.
Receive Queue Full
Number of cells dropped due to a full receive queue.
- Carrier
- Indicates that a carrier has been detected on the receive
line.
- -p
- Display physical layer statistics.
- -o
- Display physical media device (PMD) error statistics.
- -a
- Display ATM layer statistics.
- -0
- Display statistics about ``null'' AAL traffic.
- -4
- Display statistics about AAL 4 traffic.
- -5
- Display statistics about AAL 5 traffic.
- -d
- Display device specific statistics.
You cannot run this command in partner mode.
In takeover mode, the counters represent the combined statistics of the
live filer and failed filer.
No such device
This indicates that the specified device is invalid.
