This example shows how to create an Ethernet VLAN in global configuration mode and verify the
configuration:

Releases 12.1(11b)E and later support VLAN configuration in global configuration mode.
Releases 12.1(13)E and later support extended-range VLANs.
RPR+ redundancy does not support a configuration entered in VLAN database mode. Use global
configuration mode with RPR+ redundancy.
Because Layer 3 ports and some software features require internal VLANs allocated from 1006 and
up, configure extended-range VLANs starting with 4094.
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 router displays a
message and does not modify the VLAN configuration.
You cannot delete the default VLANs for the different media types: Ethernet VLAN 1 and FDDI or
Token Ring VLANs 1002 to 1005.
When you delete a VLAN, any LAN ports configured as access ports assigned to that VLAN become
inactive. The ports remain associated with the VLAN (and inactive) until you assign them to a new
VLAN.
