JUNOSe 11.1.x Link Layer Configuration Guide
If you merge subranges by using SNMP, the new merged subrange takes the lowest
instance value of the incorporated subranges. For example, if a VLAN range has three
subranges with instance values of 2, 4, and 5 and the subranges with instance values
of 2 and 5 are merged, the new merged subrange has an instance value of 2.

Changing the Administrative State of VLAN Subranges

VLAN subranges have an administrative state that enables you to remove dynamic
VLAN subinterfaces on various subranges that belong to a single VLAN range. This
functionality is important because subrange removal requires that no dynamic VLAN
subinterfaces exist for any circuit on that subrange. The removal operation fails if
any such interfaces exist.
By default, the administrative state of a VLAN subrange is up. When you change the
administrative state to down by using the vlan bulk-config shutdown command,
the router deletes all dynamic VLAN subinterfaces on the affected subranges. You
can use the show vlan subinterface command to monitor the progress of the removal
of all dynamic VLAN subinterfaces for the specified subrange.
No additional dynamic VLAN subinterfaces can be created for the subrange until you
restore the administrative state to up by using the no vlan bulk-config shutdown
command.
The following example specifies the original VLAN subranges.
You cannot specify a partial subrange; the specified subrange must exactly match a
subrange that has already been configured. The following command changes the
administrative state of the second subrange (S-VLAN IDs 201–250 and VLAN ID 2)
to down. The router removes all dynamic interface columns built on any of the VLAN
IDs or S-VLAN IDs in this subrange. No additional dynamic VLAN subinterfaces can
be created until you change the administrative state to up.
The following command changes the administrative state of this same VLAN subrange
to up.
You can also change the administrative state of VLAN subranges that are based on
agent-circuit-identifier information. For example, assume that the following command
is issued to configure a VLAN subrange based on agent-circuit-identifier information:
The following command changes the administrative state of this same VLAN subrange
to down:
