What is the Normal VLAN range?

The Normal VLAN range refers specifically to the VLAN IDs that can be assigned to standard VLANs on Ethernet networks. This range is from 1 to 1005.

VLANs are used to segment networks at the data link layer (layer 2) and provide separation for different broadcast domains. VLAN IDs in the range of 1 to 1005 are considered normal because they can be configured directly on Cisco switches and are part of the common range that most network devices support for VLAN assignment.

IDs 1006 to 4094 are classified as extended VLANs; they are not used in the same way as normal VLANs in most standard implementations and require specific configurations support. Additionally, while VLAN ID 0 is valid, it is reserved and does not refer to a normal VLAN; it is used to indicate untagged packets in 802.1Q tagging. A VLAN ID of 4095 is also reserved for internal use and not for standard VLANs. Therefore, focusing on the range of 1 to 1005 correctly identifies the normal VLAN range in Cisco networks.
