When connecting a server directly to a multilayer switch, which type of cable should be used without MDI-X?

When connecting a server directly to a multilayer switch, a straight-through cable is the appropriate choice for several reasons.

A straight-through cable is designed for connecting devices that do not have the same transmit and receive functionality. In this scenario, the server and the multilayer switch have different roles, with one serving as a host and the other as a network device. The straight-through cable allows data to flow directly from the server’s network interface to the switch’s interface without requiring any additional configuration.

In contrast, other types of cables such as crossover cables are primarily used to connect two devices of the same type, like two computers or two switches, where both devices need to transmit and receive signals on the same pair of wires. Coaxial cables are typically used for cable television and internet connections, and a rollover cable is often used for connecting devices to a console port, which is not suitable for direct server-to-switch connections.

Therefore, using a straight-through cable ensures proper connectivity between the server and the multilayer switch, allowing for effective communication and data transfer without the need for MDI-X adjustments.
