The Switch 2650 also supports Trunking, which allows multiple network
cables to be used for a single network connection without causing a data
path loop. For more information on Spanning Tree and Trunking, see the
Management and Configuration Guide, which is on the Documentation
CD-ROM that came with your switch.
Check the port configuration. A port on your Switch 2650 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. For more information, see
the Management and Configuration Guide, which is on the Documenta-
tion CD-ROM that came with your switch.
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 HP Procurve web site,, in the Information Library section.
