Allows you to change the reserved VLAN range by specifying the starting
VLAN ID for your desired range.
You can change the reserved VLANs to any other 128 contiguous VLAN
ranges. When you reserve such a range, it frees up the range of VLANs
that were allocated for internal use by default, and all of those VLANs are
available for user configuration except for VLAN 4094.
To return to the default range of reserved VLANs (3968-4049 and
Note
4094), you must enter the no system vlan start-vlan reserve
command.
Copies the running configuration to the startup configuration.
You must enter this command if you change the reserved
Note
block.
Reloads the software, and modifications to VLAN ranges become effective.
