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]
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
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.
