Description: An indication of whether the UDLDP aggressive mode is enabled on this interface. If the 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. cudldpInterfaceAggressiveMode is deprecated and replaced with cudldpInterfaceAdminMode.
