Core Issue

These are the most likely causes:

  • Misconfigured IP address
  • Physical layer problems


To resolve this issue, perform these steps:

  1. Ensure that the IP address is configured correctly on the destination device.
  2. Check the physical connectivity, such as cables, hubs, switches and network cards.
  3. Ensure that the cable is working properly by trying different ports and swapping cables.

For more information, refer to the Check for Local Connectivity section of Troubleshooting TCP/IP.
