1. Troubleshooting Diagnosing with the LEDs Tip Problem Solution The port may be improperly configured or the portmay bein a blocking state by the normal operation of the Spanning Tree LACP or IGMP features Use the switch console to see if the port is part of a dynamic trunk through the LACP feature or to see if Spanning Tree is enabled on the switch and to see if the port may have been putinto a blocking state by those features The show lacp command displays the port status for the LACP feature the show spanning tree command displays the port status for Spanning Tree Also check the Port Status screen using the show interfaces command to see if the port has been configured as disabled Other switch features that may affect the port operation include VLANs and IGMP Use the switch console to see how the port is configured for these features For software troubleshooting tips see the chapter Troubleshooting inthe Management and Configuration Guide which is on the ProCurve Web site at www hp com go procurve manuals Ensure also that the device at the other end of the connection is indicating a good link to the switch If itis not the problem may be with the cabling between the devices or the connectors on the cable Troubleshooting Diagnosing with the LEDs LED Patterns for PoE Troubleshooting If the PoE Status LED is flashing that indicates a problem with the delivery
