In Figure 116, interface 3/41 is a backup interface <strong>for</strong> 3/42, and 3/42 is in <strong>the</strong> down state, as shown in<br />

message Message 16. If 3/41 fails, 3/42 transitions to <strong>the</strong> up state, which makes <strong>the</strong> backup link active. A<br />

message similar to Message 16 appears whenever you configure a backup port.<br />
