If necessary though, you can modify the configuration of the ports on the
Switch 5300xl Series 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 5300xl 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 that is on the ProCurve Web site,
www.procurve.com
for more information.
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 Web site,
www.procurve.com , in the Information Library section.
