vlan-id-range

Syntax

vlan-id-range vlan-id–vlan-id

Hierarchy Level

[edit interfaces interface-name unit logical-unit-number],[edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number]

Release Information

Statement introduced in JUNOS Release 8.4.

Description

Bind a range of VLAN IDs to a logical interface.

Options

number—The first number is the lowest VLAN ID in the range the second number is the highest VLAN ID in the range.

Range: 1 through 4094

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;
    

VLAN ID 0 is reserved for tagging the priority of frames.
