NOTES

A loopback test will cause the remote port of the monitored bridge to temporarily go off-line. This will cause Spanning Tree to reconÞgure at the monitored bridge (the bridge will go into Standby state as it listens to the network and learns the topology).

Your NB-30 icon will also change color to indicate a test in progress (informational state).
