Verifying the data path

  1. Enter the ping command to test for a complete path to the end device 
    device# ping 10.24.81.2

    Note

    Some devices do not display TX Power.
  4. Enter the show arp vrf command.
  5. Enter the show mac-address-table command to verify that the MAC address table learns new values.

    The new MAC address should appear here.

  6. Enter the show lldp neighbors command to verify that LLDP reports all neighbors.

    If the output does not show all neighbors, contact your device support provider.

  7. Enter the show mac-address-table command to detect whether MAC addresses learned from other network devices are present.

    Enter this command on other network devices to ensure that those devices can detect this MAC address.
