Troubleshooting

Basic Troubleshooting Tips

Because the Series 8200zl Switch behaves in this way (in compliance with the IEEE 802.3 standard), if a device connected to the switch has a fixed configuration at full duplex, the device will not connect correctly to the switch. The result will be high error rates and very inefficient communications between the switch and the device.

Ensure that all devices connected to the Series 8200zl Switch is configured to auto negotiate, or are configured to connect at half duplex (all hubs are configured this way, for example).

If necessary though, you can modify the configuration of the ports on the Series 8200zl Switch to match the configuration of the connected device. Use the switch console, the web browser interface, or ProCurve Manager to modify the port configuration.

■Check the port configuration. A port on your Series 8200zl Switch may not be operating as you expect because it has been put into a “blocking” state by Spanning Tree, GVRP (automatic VLANs), or LACP (automatic trunking). (Note that the normal operation of the Spanning Tree, GVRP, and LACP features may put the port in a blocking state.) Or, the port just may have been configured as disabled through software.

Use the switch console to determine the port’s configuration and verify that there is not an improper or undesired configuration of any of the switch features that may be affecting the port. See the Management and Configuration Guide which is on the ProCurve Web site. See page 5-1for details.

For more information on possible network problems and their solutions, refer to the technical note “Troubleshooting LAN Performance and Intermittent Connectivity Problems”, which can be found on the ProCurve Networking Web site in the Reference Library, www.procurve.com/library, in the A-Z index section.
