VLAN Table Unit Table Operation =============================== Support the following VTU operation. 0, 2 - No Operation 1 - Flush All Entries 3 - Load(1) or Purge(2) an Entry 4 - Get Next(3) 5,6 - Reserve 7 - Get/Clear Violation Data NOTE: (1) - An Entry is Loaded when the 'vtuValid' is set to a one. Load is the only 'vtuOperation' that uses the 'vtuDBNum' field and it uses it as data to be loaded along with the desired 'vtuVID'. (2) - An Entry is Purged when the 'vtuValid' is cleared to a zero. (3) - A Get Next operation finds the next higher 'vtuVID' curretnly in the database. The vtuVID value is used as the VID to start from. To find the lowest VID set the vtuVID field to ones. When the operation is done the vtuVID field contains the next higher VID currently active in the database. To find the next VID simply issue the Get Next opcode again. If the vtuVID field is returned set to a one's with the vtuValid cleared to zero, no higher VID's were found. To Search for a particular VID, perform a Get Next operation using a vtuVID field with a value one less than the one being searched for.
