Agent function


Uses ethtool and Medium Independent Interface (MII) to request the device status. If the hardware does not respond, the agent sends a ping to the hosts that are listed in the NetworkHosts attribute. If the ping test fails, the agent checks for activity on a configured interface by sampling the input packets that are received on that interface. If the agent does not detect activity, it forces activity by sending out a broadcast ping. If the agent does not receive a network reply, it migrates to the most suitable next interface.
