Troubleshooting

A.2.2 atmstat

To determine a particular failure state, enter the following command on the
remote workstation while continuously pinging:

atmstat fa0 1

PHY/ATM/AAL statistics:

Output Input Errors

ATM AAL* ATM AAL* 4B5B 4B5B ATM AAL* AAL*

Cells CS-PDUs Cells CS-PDUs Framing Hdr-CRC VPI/VCI Pay-CRC Proto

161747 153692 142289 134685 0 0 20 0 0

The failure states are determined by examining the output from the

atmstat

fa0 1

command string. The failures are classified by whether or not cells are

sent (or received) and whether or not errors are received. The output shown
below is typical of the first response from the

atmstat

fa0 1

command string.

Succeeding lines of data continue in the same column format. Refer to the fol-
lowing subsections for a description of each type of failure.
