Removing Vc Subranges; Modifying Vc Subranges - Juniper JUNOSE 11.1.X - LINK LAYER CONFIGURATION 4-7-2010 Configuration Manual

JUNOSe 11.1.x Link Layer Configuration Guide
You can create a placeholder VC range by specifying a VC range name without
specifying any subrange parameters. This VC range has no circuit reservation, but
you can assign a profile to it, and add subranges later as desired. The following
commands illustrate this approach.

Removing VC Subranges

You can remove VC subranges from an existing VC range if no dynamic ATM 1483
subinterfaces currently exists for any circuit within those subranges. The removal
operation fails if any such dynamic ATM 1483 subinterface exists. You must first
remove the dynamic ATM 1483 subinterfaces before you can remove the subranges.
Removal of a subrange automatically results in the removal of all overriding profile
assignments on that subrange.
You can remove only a single specific VC subrange at a time. The following example
specifies the original VC subranges.
The following command removes one subrange (1, 1, 101, 150) and leaves the
remaining subranges, and the named VC range, test, intact.
To remove more than one VC 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 VC, and the named VC range, at the same time.

Modifying VC Subranges

You can shorten or expand a subrange by modifying the subrange values of a VC
range. You can expand a subrange if none of the circuits added overlap with any
other subrange. You can shorten a subrange if none of the circuits dropped have
existing dynamic ATM 1483 subinterfaces.
You can modify only a single specific subrange at a time. The following example
specifies the original VC subranges.
The following command modifies the second subrange from (2, 2, 201, 250) to
(2, 3, 210, 230).
