Description: Number of Layer 2 Protocol Tunneling Transmitted Frames De-encapsulated.
What is cmEthernetTrafficPortHistoryL2PTTxFramesDecap?
This counter records the number of Layer 2 Protocol Tunneling frames de-encapsulated before transmission out this Ethernet port during the archived historical interval. A historical review lets the admin confirm L2PT tunneling was actively processing frames on this port during a specific past period, useful when investigating an intermittent tunnel issue reported after the fact. For example, if a customer's tunneled STP reported gaps yesterday, the admin would check cmEthernetTrafficPortHistoryL2PTTxFramesDecap for that interval to see if de-encapsulation activity dropped off.
