What is atmSuPortAtmVclStatsTotalLOCSeconds?

This counter totals the number of seconds during which the Virtual Channel Link has experienced loss of continuity, meaning no data cells and no Continuity Check cells were received while monitoring was enabled. Network engineers use this metric to calculate link availability and uptime, and to identify virtual channels that are experiencing frequent outages requiring investigation or rerouting. A LOC counter showing 1,800 seconds (30 minutes) during a month of monitoring indicates the virtual channel is only 99.9% available and may not meet SLA requirements for critical traffic.
