profile to it, and add subranges later as desired. The following commands illustrate this
approach.
host1(config-if)#atm bulk-config test
host1(config-if)#profile atm1483 bulk-config-name test atmProfile
host1(config-if)#atm bulk-config test vc-range 4 4 401 450 vc-range 6 6 601 650

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.
host1(config-if)#atm bulk-config test vc-range 1 1 101 150 vc-range 2 2 201 250 vc-range
5 5 501 550 vc-range 3 3 301 350
The following command removes one subrange (1, 1, 101, 150) and leaves the remaining
subranges, and the named VC range, test, intact.
host1(config-if)#no atm bulk-config test vc-range 1 1 101 150
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.
host1(config-if)#no atm bulk-config test

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.
host1(config-if)#atm bulk-config test vc-range 1 1 101 150 vc-range 2 2 201 250 vc-range
5 5 501 550 vc-range 3 3 301 350
The following command modifies the second subrange from (2, 2, 201, 250) to
(2, 3, 210, 230).
host1(config-if)#atm bulk-config test modify vc-range 2 3 210 230
The router retains any overriding profiles assigned to a subrange after you modify the
subrange if the override assignment still falls within the modified subrange. If the
assignment falls outside of the newly modified subrange, the router drops the overriding
profile assignment.
