"Introduction" Within a switched network, it is possible to segment and organize flexibly through VLANs. VLANs can group devices in a LAN. A group of devices in a VLAN communicates as if it were connected to the same line. VLANs are based on logical connections, not physical connections. Types of VLANsThere are many different types of VLANs used in modern networks. Some VLAN types are defined by traffic category. Some other VLAN types are defined by specific features.Data VLAN: used to deliver u

The loop has a great impact on the network. Spanning Tree protocol is a good solution to this problem.The idea of spanning a tree protocol topology is that, regardless of the physical connection between switches, the switch can automatically discover a network with no loop topology, and the network of the logica
