Because Layer 3 ports and some software features require internal VLANs allocated from 1006 and
up, configure extended-range VLANs starting with 4094 and work downward.
You can configure extended-range VLANs only in global configuration mode. You cannot configure
extended-range VLANs in VLAN database mode.
Layer 3 ports and some software features use extended-range VLANs. If the VLAN you are trying
to create or modify is being used by a Layer 3 port or a software feature, the switch displays a
message and does not modify the VLAN configuration.

Purpose
Enters global configuration mode.
Adds an Ethernet VLAN.
You cannot delete the default VLANs for these media types:
Note
Ethernet VLAN 1 and FDDI or Token Ring VLANs 1002 to
1005.
When you delete a VLAN, any LAN interfaces configured as
access ports assigned to that VLAN become inactive. They
remain associated with the VLAN (and thus inactive) until you
assign them to a new VLAN.
You can use the no keyword to delete a VLAN.
When the prompt reads
Switch(config-vlan)#,
vlan-configuration mode. If you wish to change any of the parameters
for the newly created VLAN, use this mode.
Returns to enable mode from vlan-configuration mode.
Verifies the VLAN configuration.
