What is the extended VLAN range?

The extended VLAN range refers to the range of VLAN numbers that can be configured on a network switch when using VLAN Trunking Protocol (VTP) in a switch stack. This range specifically includes VLANs numbered from 1006 to 4094. Extended VLANs allow for a significant number of VLANs beyond the standard range of 1 to 1005, giving network administrators the ability to segment networks effectively.

The range is important because it facilitates the creation of multiple logical networks within the same physical network, allowing for improved organization, efficiency, and security in large and complex networking environments. With the ability to utilize VLANs in this extended range, networks can support a greater number of users and a wider variety of applications, which is essential for modern enterprise networking needs.

Understanding this range is crucial for anyone involved in network design and administration, particularly in large organizations where segmentation of network traffic is necessary for performance and security.
