        aggressive mode is set to 'true', an active port may 
        be shutdown in case of the abrupt loss of its 
        neighbor(s) because the loss of communication
        (heartbeat) with the neighbor(s) is assumed to be
        caused by a fault; thus, the cudldpInterfaceOperStatus
        of the active port will be 'shutdown'. Instead, when
        the aggressive mode is set to 'false', and if there
        is a loss of communication with the neighbor(s), then
        the cudldpInterfaceOperStatus of the active port
        will be 'indeterminant'. 
        Therefore, this mode is recommended 
        only for links that don't use hubs, media converters 
        or similar devices, and where the unexpected loss of 
        the port's neighbor is not an admissible condition.
