Summary of Qué son las VLAN, para qué sirven y cómo funcionan. Curso de redes desde 0 | Cap 20 |
VLANs (Virtual Local Area Networks) are virtual networks that allow for the logical separation of networks within a physical network.
VLANs offer advantages such as network segmentation, broadcast traffic management, and enhanced security.
VLANs can be set up using managed switches, where different networks are created virtually instead of physically.
Physical network segmentation requires multiple switches, while logical network segmentation can be achieved with a single managed switch.
VLANs help in isolating network traffic, improving security by preventing issues in one network from affecting others.
trunk ports are used to carry multiple VLANs over a single cable, allowing for efficient network connectivity.
Tagged ports are used to differentiate VLAN traffic, while untagged ports can only belong to a single VLAN.
devices within a VLAN can communicate with each other, and trunk ports are used to connect switches and routers efficiently.
VLAN configuration allows for the efficient management of multiple networks on the same hardware, similar to having multiple identities on social media platforms.
