show resource
show resource vlan (or another resource name from show resource ?)
show vdc resource detail
show vdc resource vlan (or another resource name) detail
show vdc vdc-name resource
show vdc vdc-name resource vlan (or another resource name)


When the user has frequently created/deleted vlans across multiple VDCs, the user is more susceptible to this issue.
