NAME

adstat - show ATM device driver statistics

SYNOPSIS

adstat [ -poa045d ] device [ interval ]

DESCRIPTION

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.

OPTIONS

-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.

CLUSTER CONSIDERATIONS

You cannot run this command in partner mode.

In takeover mode, the counters represent the combined statistics of the live filer and failed filer.

ERRORS

No such device
This indicates that the specified device is invalid.
