Catalyst 4500 series switches support 4096 VLANs in accordance with the IEEE 802.1Q standard. These VLANs are organized into several ranges; you use each range slightly differently. Some of these VLANs are propagated 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:
•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.
Are you an experienced network professional?
If yes, we'd like to understand how we can better organize network management activities in a way that makes sense to you. Your response will help Cisco improve a product feature that could benefit you.&nb...
