This value, carried in an L2VPN OAM trap, reports the MPLS label the local router uses when transmitting pseudowire traffic toward the peer, or zero if not applicable. An admin uses this alongside hwL2vpnInLabel to verify the label pair in use for the affected pseudowire when cross-referencing MPLS forwarding tables during troubleshooting. For example, confirming the reported hwL2vpnOutLabel matches what the peer PE expects helps rule out a label mismatch as the fault's cause.
