Changing the Range of Reserved VLANs
Procedure
Step 1
Step 2
Step 3
Step 4
Step 5
This example shows how to change the range of reserved VLANs:
switch# configuration terminal
switch(config)# system vlan 2000 reserve
This will delete all configs on vlans 2000-2081. Continue anyway? (y/n) [no] y
Note: After switch reload, VLANs 2000-2081 will be reserved for internal use.
This requires copy running-config to startup-config before
switch reload. Creating VLANs within this range is not allowed.
switch(config)#
You must reload the device for this change to take effect.

Purpose
Enters global configuration mode.
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
Note
(3968-4049 and 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
Note
reserved block.
Reloads the software, and modifications to VLAN ranges
become effective.

7000 Series NX-OS Fundamentals Configuration Guide,
