The Fundamentals of Ethernet Cabling in an Enterprise Data Network
UTP cable has 4 pairs or 8 wires with different colors where each end of the cable terminates in an RJ-45 plug. The color-coding of the copper ethernet cable was standardized by EIA (Electronic Industries Alliance) and TIA (Telecommunications Industry Association) where we have two standards: EIA/TIA 568-A and EIA /TIA 568-B.
A tip on how to memorize UTP cabling pinout for standards T568A …
And by knowing the two ends of a cable you should be able to recognize it as a straight-through (same standard on both ends, either T568A or T568B) or a crossover cable (T568A standard on one end and T568B on the other end). I uploaded to CLN a simple text I wrote as a tip on how to take in and/or memorize the pinout for those two EIA/TIA ...

TDR Feature: Status in UTP Pairs - Cisco Learning Network
The "Open" state indicated a break in one of the pairs of cable during the UTP wiring path, and the "Short/Crosstalk" state occurs when the signal of one cable is mixed with the signal of another cable. It can happen when the cables are damaged or you have a worn or broken RJ45 plug.
Rollover Cables! - Cisco Learning Network
2023年4月22日 · Your computer doesn't have a COM port in RJ45 form-factor. Your only RJ45 port is your Ethernet adapter, so these are completely different standards and they are totally incompatible. The rollover cable is normally used when you need to extend a console reach over a longer distance, than standard console cables.

Ethernet/FastEthernet/GigabitEthernet Cable Compatibility Queries
If your using ethernet cable and an RJ45 jack it's going to support 10/100/1000 in most cases Cat5E for instance. Beyond that it's the configuration on the interface that determines what cable pairs are used. I've done cable tests from 2960s and seen which pairs are used for what, gig connectivity and full duplex, all pairs were good.

Codificación de colores para los estándares del cable Ethernet. En primer lugar vamos a ver los colores de cada uno de los 8 hilos del cable UTP. Ahora vamos a distinguir la distribución de cada par en el Plug RJ-45 según los dos estándares: EIA/TIA 568-A y EIA/TIA 568-B
CCNA Prep Technical Question #12: Console port of a Cisco router
A UTP cable must be terminated as a rollover or console cable in order to connect it to a Cisco router from a PC serial port. Never connect it to an Ethernet port! Be mindful that it is a serial cable. E: For console access, you can utilise a Cisco USB to Serial Adapter Cable. Newer Cisco routers and switches also feature USB ports.
