Review the HP FlexFabric Switch configurations and examine all access switch ports. Each access switch port not in use should have membership to an inactive VLAN that is not used for any purpose and is not allowed on any trunk links.

If there are any access switch ports not in use and not in an inactive VLAN, this is a finding.
