I am preparing for the ICND1 and have a question. I just took a Boson practice exam and the exam is telling me that the correct way to connect a PC to a router's Fa0 interface with is with a crossover cable. How can this be true? In my lab I am using a straigh-thru cable to connect to my router's Fa0 interface with success (from the RJ45 port on my laptop)
Could this be a mistake on the part of the testing software?
Any help would be greatly appreciated.
The port I am connecting to is a 10/100 Ethernet port - hence the reason I can use a straight thru cable.
I guess the question was aiming at connecting a PC to a router via the console port which would then require a crossover cable.
Thanks for your quick reply.
PC to Router = Ethernet Cross-Over
On the right, second from the bottom.
Both of these devices are expecting to connect to a switch. When connecting them together, we need to use a cross-over cables so that the transmit pair from 1 device, goes to the receive pair of the other device.
Thank you for the reply and the diagrams as well. This is my first post and it is very refreshing to see even a CCIE respond to a simple question about the CCENT exam.
The easiest way I have found at remembering what cables for which devices is remembering that devices that transmit and receive on the same pins require cross-over, ie. switch-switch, pc-router. Likewise devices that transmit and receive on opposite pins require straight-through, ie. switch-pc, switch-router.
Devices that transmit on 1,2 and receive on 3,6
3)Wireless Access Point AP
4) Networked printers
Devices that transmit on 3,6 and receive on 1,2
The Boson exam I have came with the ICDN1 Book written by Odom. I am considering purchasing the Transcender exams as well. Do you or anyone out there have any experience with them with regards to the Cisco exams?
I am using both the Boson and the Cisco Press practice test. Cisco is included with the Odom book. I purchased the Boson exam online
Both run in the Boson exam environment. Just be aware the Boson will disable the "smart mode" for the Cisco test if you update. Seems rather unethical for Boson to disable this function in order to sell there own product. But aside from the rather dubious ethics, the practice exams both seem good.
Console port uses a rollover cable, the pin layout on 1 end is 1-8, while the other end is 8-1, exactly opposite.
I still can't remember the pins color coding though, don't do much layer1 stuff in my work.
Auto-MDIX (automatic medium-dependent interface crossover) is a computer networking technology that automatically detects the required cable connection type (straight-through or crossover) and configures the connection appropriately, thereby removing the need for crossover cables to interconnect switches or connecting PCs peer-to-peer. When it is enabled, either type of cable can be used and the interface automatically corrects any incorrect cabling. For Auto-MDIX to operate correctly, the speed on the interface and duplex setting must be set to "auto". Auto-MDIX was developed by HP engineers Dan Dove and Bruce Melvin.
"Home broadband routers have become an exception to the rule of crossover cable between PC and router: modern consumer routers contain logic to automatically detect crossover cables and allow them to function with other types of Ethernet devices."
That could be a stress reliever of it was incorporated into commercial Cisco routers also.
