Note: Configuring vlan-id-range with the entire vlan-id range is an unnecessary waste of system resources and is not best practice. It should be used only when a subset of VLAN IDs (not the entire range) needs to be associated with a logical interface. If you specify the entire range (1-4094), it has the same result as not specifying a range; however, it consumes PFE resources such as VLAN lookup tables entries, and so on.

The following examples illustrate this further:

• Inefficient

  [edit interfaces interface-name]                                   
  vlan-tagging;
  unit number {
      vlan-id-range 1-4094;
  }
  

• Best Practice

  [edit interfaces interface-name]                                   
  unit 0;
