You can change the administrative state of all subranges in a bulk-configured VLAN
range at the same time by issuing the command without specifying any subranges.
When you shut down a named bulk configuration, all VLAN ranges belonging to that
bulk configuration, including those based on double-tagged S-VLANs or
agent-circuit-identifier information, are disabled.
The following command shuts down all four subranges belonging to the named VLAN
range, test, regardless of their current state.
The time required for the router to complete an administrative state change depends
on the number of VLAN subranges configured.
vlan bulk-config
vlan bulk-config modify
host1(config-if)#vlan bulk-config test shutdown
Use to create a bulk-configured VLAN range on a static VLAN major interface for
use by a dynamic VLAN subinterface.
For detailed information about how to use this command, see "vlan bulk-config"
on page 627.
Example
host1(config)#vlan bulk-config test1 svlan-range 200 250 2
Use the no version to remove the specified VLAN range from the VLAN major
interface, to remove the specified subranges from the specified VLAN range, or
to remove all subranges from the specified VLAN range. The no version also
removes any overriding profile assignments for VLAN IDs or S-VLAN IDs within
the deleted VLAN range or VLAN subrange.
See vlan bulk-config.
Use to expand or shorten the range of the specified VLAN subrange. You can
modify only a single specific subrange at a time.
You can expand a subrange if none of the added VLAN IDs or S-VLAN IDs overlap
with any other subrange. You can shorten a subrange if none of the dropped
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.
Modifying a subrange so that it completely includes at least one other subrange
from within the same VLAN range effectively merges the subranges. Each
subrange that is merged with another frees up a subrange for subsequent
configuration. The subranges that are merged do not need to be adjacent to each
other.
The router retains any overriding profiles assigned to a subrange if the assignment
falls within the modified subrange. If the assignment falls outside of the newly
modified subrange, the router drops the overriding profile assignment. If two
subranges are merged, the router retains overriding profiles that were assigned
to the separate subranges and applies the overriding profiles to the newly merged
subrange.
