Removing VLAN Subranges

You can remove VLAN subranges from an existing VLAN range if no dynamic VLAN subinterfaces currently exists for any circuit within those subranges. The removal operation fails if any such dynamic VLAN subinterface exists. You must first remove the dynamic VLAN 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 VLAN subrange at a time. The following example specifies the original VLAN subranges.



host1(config-if)#vlan bulk-config test svlan-range
101 150 1 1 

 svlan-range
201 250 2 2 svlan-range 501 550 5 5 svlan-range 301 350 3 3

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.



host1(config-if)#no vlan bulk-config test
svlan-range 101 150 1 1

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.



host1(config-if)#no vlan bulk-config test
svlan-range 700 750  agent-circuit-identifier

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.



host1(config-if)#no vlan bulk-config test
