Description: Number of Layer 2 Protocol Tunneling Transmitted Frames De-encapsulated.

What is cmEthernetTrafficPortStatsL2PTTxFramesDecap?

This counter records the number of Layer 2 Protocol Tunneling frames that were de-encapsulated before transmission out this Ethernet port during the current interval. It confirms to the admin that L2PT, used to tunnel customer control-plane protocols like STP transparently across a provider network, is actively processing frames on this port as expected. For example, if a customer's STP BPDUs aren't reaching the far end of an L2PT tunnel, the admin would check whether cmEthernetTrafficPortStatsL2PTTxFramesDecap is incrementing to confirm de-encapsulation is happening on this port.
