Shows Asynchronous Transfer Mode adapters statistics.
The atmstat command displays Asynchronous Transfer Mode (ATM) adapter statistics. The user can optionally specify that the device-specific statistics be displayed in addition to the device generic statistics. If no flags are specified, only the device generic statistics are displayed. For information on statistic from the atmstat command, see ATM adapter statistics in the AIX® Version 7.1 Networks and communication management.
If an invalid Device_Name is specified, the atmstat command produces an error message stating that it could not connect to the device.
| Item | Description |
|---|---|
| -d | Displays detailed statistics. |
| -r | Resets all the statistics back to their initial values. This flag can only be issued by privileged users. |
| Item | Description |
|---|---|
| Device_Name | The name of the ATM device, for example, atm0. |
To display the adapter generic statistics for atm0, enter:
