What is the range of VLAN IDs on a switch?

The range of VLAN IDs on a switch is from 1 to 4095. This is defined by the IEEE 802.1Q standard, which is used for VLAN tagging in Ethernet networks. VLAN IDs are a way to segment network traffic and separate different broadcast domains on a LAN.

When creating VLANs, it's important to understand that VLAN IDs 0 and 4095 are reserved. VLAN ID 0 is used for priority tagging and does not represent a standard VLAN, while VLAN ID 4095 is reserved for internal use, allowing switches to create and manage VLANs efficiently. Consequently, the usable VLAN IDs for network administrators range from 1 to 4094.

This range allows for a substantial number of VLANs, accommodating various network designs and requirements, particularly in complex or larger enterprise environments. Thus, the correct answer reflects the full spectrum of available VLAN IDs that can be configured and utilized within compliant switching environments.
