        "Operating state of DLDP on the port.
        This object has six defined values:

        This status does not appear in the 'h3cDLDPPortDLDPState' object (below)
        because the port which is not enabled DLDP does not appear in
        'h3cDLDPPortDLDPTable', it appears in 'h3cDLDPPortStateTable'.
        - 'inactive', which indicates that the Ethernet port enables DLDP and
        the link status of the port is down.
        - 'active', which indicates that the Ethernet port enables DLDP and
        the link status of the port is up.
        - 'advertisement', which indicates that all neighbors of the port are
        bidirectional communication.
        - 'probe', which indicates that the port sends PDU to detect
        the communication mode between it and it's neighbors.
        - 'disable', which indicates that an unidirectional communication
        between the port and it's neighbor.
