Modifying Vlan Subranges - Juniper JUNOSE SOFTWARE 11.0.X - LINK LAYER CONFIGURATION GUIDE 4-1-2010 Configuration Manual

JUNOSe 11.0.x Link Layer Configuration Guide
a subrange automatically results in the removal of all overriding profile assignments
on that subrange.
You can remove only a single specific VLAN subrange at a time. The following example
specifies the original VLAN subranges.
The following command removes one subrange encompassing S-VLAN IDs 101–150
with VLAN ID 1 and leaves the remaining subranges, and the named VLAN range,
test, intact.
The following command removes a subrange that includes S-VLAN IDs 700–750,
and that is based on agent-circuit-identifier information from the named VLAN range,
test.
To remove more than one VLAN subrange, you must issue multiple removal
commands, one for each subrange. You cannot remove only part of a subrange. A
removal command cannot encompass more than one subrange, even if the subranges
are adjacent. However, if you do not specify any subranges, you can remove all
subranges in the VLAN, and the named VLAN range, at the same time.

Modifying VLAN Subranges

You can shorten or expand a subrange by modifying the subrange values of a VLAN
range. You can expand a subrange if none of the VLAN IDs or S-VLAN IDs added
overlap with any other subrange. You can shorten a subrange if none of the VLAN
IDs or S-VLAN IDs have existing dynamic VLAN subinterfaces. You can also modify
an existing subrange by configuring it to use agent-circuit-identifier information rather
than a range of VLAN IDs.
You can modify only a single specific subrange at a time. The following example
specifies the original VLAN subranges encompassing S-VLAN IDs 201–250 with VLAN
ID 2.
The following command modifies the second subrange from S-VLAN IDs 201–250
with VLAN ID 2 to S-VLAN IDs 210–230 with VLAN IDs 2–3.
The following command modifies the third subrange from S-VLAN IDs 501–550 with
VLAN ID 5 to S-VLAN IDs 501–550 with user identification that is based on
agent-circuit-identifier information.
