Example Neighbor Statistics

The following output was recovered from a single-attached station using the command shown. A temporary fault condition was simulated by disconnecting the FDDI cable from the SunFDDI card and then reconnecting it.

Note the following observations regarding this example:

• Accumulated statistics are displayed automatically after every tenth interrogation.

• The combination of PhyS=NONE and the loss of frame activity indicates that the station is disconnected from the network.
