Release Information

Statement introduced in Junos OS 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

On SRX240, SRX300, SRX320, SRX340, SRX345, SRX550M, and SRX650 devices, the VLAN range from 1 to 4094 on inet interfaces and the VLAN range from 1 to 3967 on Ethernet switching interfaces. On Ethernet switching interfaces, the VLAN range from 3968 to 4094 falls under the reserved VLAN address range, and the user is not allowed to configure VLANs in this range.

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

  • Best Practice

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