The number of Unavailable Seconds (UAS).
What is cmEthernetTrafficPortHistoryUAS?
This OID holds a running count of unavailable seconds (periods when no valid data could be transmitted) on an Ethernet port over a history interval. High unavailable seconds indicate the port experienced noise, disconnection, or signal degradation. An operator monitors this metric over time to identify ports becoming unreliable and plan maintenance before total failure occurs.
