Which cable type must be used when connecting a router and switch together using these criteria?
• Pins 1 and 2 are receivers and pins 3 and 6 are transmitters.
• Auto detection MDI-X is unavailable.
Which cable type must be used when connecting a router and switch together using these criteria?

• Auto detection MDI-X is unavailable.
To connect a router and switch together where pins 1 and 2 are receivers and pins 3 and 6 are transmitters, and auto-detection MDI-X is unavailable, a crossover cable must be used. This is because a crossover cable is designed specifically to accommodate the exact pinouts described, ensuring proper communication between the devices without relying on auto MDI-X. In conventional practice, crossover cables are used to connect similar devices, and since routers and switches without auto MDI-X need this configuration to communicate, a crossover cable is required.
Guys, it's a crossover cable. It literally says: "Pins 1 and 2 are receivers and pins 3 and 6 are transmitters"
Weird question. The given criteria don't apply to both devices; a switch receives on pins 1 & 2, and transmits on 3 & 6. A router does the opposite, transmitting on pins 1 & 2 and receiving on 3 & 6. Conventionally, a router to switch is always a straight-through. Crossover is only for similar devices, such as connecting multiple switches together, or connecting two routers together. If we assume the question is just asking us what cable type we need to connect a switch and router together, the answer is invariably a straight-through cable. However, if we are supposed to assume the given criteria apply to *both* devices, then the answer is of course a crossover. I'll assume Cisco isn't asking us to envision such a bizarre parallel reality. D it is.
Option D You are describing a scenario where a straight-through Ethernet cable (also known as a "patch cable") should be used. In a straight-through cable, each wire on one end of the cable is connected to the same pin on the other end. This type of cable is commonly used to connect different types of devices, such as a router to a switch, where the transmit pins on one end are connected to the receive pins on the other end. Ensure that both the router and the switch are configured for the same Ethernet standard (e.g., both support Gigabit Ethernet) and use a straight-through cable to connect them. If auto MDI-X is unavailable, it means you should not use a crossover cable, as a straight-through cable is required for proper communication between the router and switch in this case.

Straight-through Cables. These two types of ethernet cable are commonly used in most computer networking transmissions. A straight-through cable is used in local area networks to connect different devices like a computer to a network hub such as a router, router and switch, PC and switch, and so on.
The answer is correct, it's crossover.
this is a straight cable output: The straight through RJ45 cable is commonly used to connect network cards with hubs on 10Base-T and 100Base-Tx networks. On network cards, pair 1-2 is the transmitter, and pair 3-6 is the receiver. The other two pairs are not used. On hubs, switches and routers, pair 1-2 is the receiver and 3-6 the transmitter. Because of this a straight through RJ45 cable can be used to connect network cards to hubs.
A switch, on the other hand, is considered an intermediary device, and its Ethernet ports are typically configured as MDI-X (Media Dependent Interface Crossover), which has the transmit and receive pins crossed internally. Therefore, when connecting a switch to a router or a PC without Auto-MDIX, a straight-through cable is used. To summarize: PC to Router (without Auto-MDIX): Crossover cable PC to Switch (without Auto-MDIX): Straight-through cable Router to Switch (without Auto-MDIX): Straight-through cable When connecting network devices of the same type without Auto-MDIX, you typically use a crossover cable. Here’s what you would use for each scenario: Switch to Switch: Crossover cable Router to Router: Crossover cable PC to PC: Crossover cable
it´s D two different devices (router DTE) to (switch DCE) using a cable with pins 1,2 as recievers and 3,6 as transmitters. it´s clearly a straight cable. A straight-through Ethernet cable is wired the same way at both ends. This cable uses pins 1, 2, 3, and 6. The send and receive wires are not crossed. You should use a straight-through Ethernet cable when connecting dissimilar devices. A crossover Ethernet cable is a cable that has the send and receive wires crossed at one of the ends. In a Category 5 cable, the 1 and 3 wires are switched and the 2 and 6 wires are switched at one end of the cable. You should use a crossover cable when connecting similar devices. https://www.ciscopress.com/articles/article.asp?p=2114358#:~:text=You%20should%20use%20a%20straight,or%20a%20hub%20(DCE).
Different devices don't requires cross over cables
Router to Switch usually requires a straight-through cable connection, however, when Auto detection MDI-X is unavailable, this changes things. Now you would need a crossover cable to allow the different devices to function properly. Older equipment with an older answer, hence why we want to think it's a straight through cable when in fact it is not.
