Module: CIENA-CES-MPLS-MIB
OID (symbolic): CIENA-CES-MPLS-MIB::cienaCesMplsPwActiveTunnelIndex

Access: read-only
Description: Specifies the active transport tunnel index in one of the cienaCesMplsTunnel/cienaCesGmplsTunnel tables for the pseudowire
What is cienaCesMplsPwActiveTunnelIndex?
This is the table index of the tunnel that is actually, currently carrying this pseudowire's traffic, used to look up the live tunnel's full details in whichever tunnel table matches the active tunnel type. Comparing this against the configured tunnel index is the definitive way to detect whether a protection switchover has moved this PW's traffic onto a different tunnel than originally provisioned. This is the specific value an automated monitoring tool would poll to detect tunnel failovers affecting this pseudowire without needing to compare tunnel names as strings.
