Cisco Packet Tracer - VLANs com Trunk
A VLAN (Virtual Local Area Network) is a virtual network that allows devices in different physical locations to be grouped into a single logical network.
A VLAN is created through software, so a switch with technical specifications that allow VLAN configuration is required.
VLANs are used to divide a network into different groups of devices based on functions, departments, or physical locations. By segmenting the network into VLANs, security policies can be implemented, among other actions.
What is a Trunk Port?
A trunk port is designed to carry multiple VLANs (Virtual LANs) simultaneously, allowing VLAN data to be transmitted through a single port. Trunk ports are typically used to connect switches to other switches, routers, or servers that need access to multiple VLANs.
Packet Tracer is software developed by Cisco and widely used for teaching and learning about Computer Networks. It is commonly used in technical schools and universities because it allows the simulation of a network environment (LAN and WAN) without the need to use real physical equipment and devices - which require large budgets and very large laboratories.
