What is atmSuPortAtmVclStatsTxTotalAISCells?

This counter logs the number of AIS (Alarm Indication Signal) cells transmitted by the ACE20 to the far end on the Virtual Channel Link to alert the remote switch that this side has detected a problem. Network engineers use this counter to confirm that alarm notifications are being sent when appropriate, and an increase indicates that this switch is in alarm state and is warning the far end. If this counter increases from 0 to 500 cells within one minute after you notice a port error, it confirms that the switch has detected the failure and is notifying the remote side to handle the outage gracefully.
