Finding what vlans are set on a switch port is a very needed thing for almost any config changes in Procurve software. This entry shows a quick way to check the vlans both tagged/untagged on a procurve. This works for all procurve I believe, but I am testing on a J9773A 2530 switch. This is a simple entry but might help someone out.
To show vlans associated with the ports the command “show vlan ports X” can be used, and to find out more info like tagged/untagged you can add the “detail” to the command to get more info. For example to get info for port 1
