Chapter 10 Configuring VLANs

VLAN Ranges

Catalyst 4500 series switches support 4096 VLANs in accordance with IEEE 802.1Q. These VLANs are
organized into several ranges; you use each range slightly differently. Some of these VLANs propagate
to other switches in the network when you use a management protocol, such as the VLAN Trunking
Protocol (VTP). Other VLANs are not propagated, and you must configure them on each applicable
switch.
There are three ranges of VLANs:

1. You can configure these VLANs as normal-range VLANs by setting the VLAN type to Ethernet using the set vlan type
2. With VTP version 3, extended-range VLANs are propagated.

Normal-range VLANs: 1–1000, 1002–1005
Extended-range VLANs: 1025–4094
Note The term nonreserved VLANs is used to denote any VLANs that are not reserved by Cisco;
this includes normal-range and extended-range VLANs.
Note With VTP version 3, you can manage extended-range VLANs 1025–4094. These VLANs
are propagated with VTP version 3.
