A network technician receives a report from the server team that a server's network connection is not working correctly. The server team confirms the server is operating correctly except for the network connection. The technician checks the switchport connected to the server and reviews the following data:



Which of the following should the network technician perform to correct the issue?

  • A. Replace the Cat 5 patch cable with a Cat 6 cable.
  • B. Install a crossover cable between the server and the switch.
  • C. Reset the switchport configuration.
  • D. Use NetFlow data from the switch to isolate the issue.
  • E. Disable MDIX on the switchport and reboot the server.

The answer is A, as others have said, but because of the bandwidth. Cat 5 = 100BASE-T, the cable is too slow for a 1000MBPS network. Anthony Sequeira "Bad cables, incorrect pinouts, or bent pins: Faulty cables (with electrical characteristics preventing successful transmission) or faulty connectors (which do not properly make connections) can prevent successful data transmission at Layer 1. A bad cable could simply be an incorrect category of cable being used for a specific purpose. For example, using a Cat 5 cable (instead of a Cat 6 or higher cable) to connect two 1000BASE-TX devices would result in data corruption. Bent pins in a connector or incorrect pinouts could also cause data to become corrupted."

Actually Cat 5 = 1000BASE-T, so wouldn't it be good in this case?

I was sourcing the information provided by Professor Messer, which said that Cat 5 = 1000BASE-T, but I realise that that might be wrong as I search on the internet and other sites state that Cat 5 = 100BASE-T

Cat 5 is under the IEEE 802.3 1000BASE-T standard, but it is now deprecated and has been updated to Cat 5e. Cat 5 has a maximum speed of 100 Mbps, while Cat 5e has a maximum speed of 1000 Mbps (1 Gbps).

While CRC's are usually indicitive of a bad cable, in this instance, MDIX is turned on meaning that whatever cable is plugged into the switch port is being used as a cross over cable. While disable MDIX would likely fix the issue, resetting the switchport settings will do this and fix anything else that could be causing issues like the speed setting.

CRC errors can also be duplex errors, so I can see where resetting the port setting might work. But I can also see where it could be a bad cable as well.

How do you analyze that there is something wrong with crc? Any help would be appropriated.

CRCs are Cyclic Redundancy Check errors, Ethernet frames that have failed the Frame Check Sequence (FCS). Basically, CRC errors are corrupted Ethernet frames that the switch rejected. CRCs are usually the result of a bad cable, bad interface, or incorrect duplex configurations on both the interface and the client device. However, a bad cable is much more likely to be the cause of CRC errors rather than a bad interface or incorrect duplex configurations.

looking at the share amount of CRCs, aka layer 1, aka physical, the only answer that makes sense is A)

why not replacing cat 5 with cat 5 cable - would it not help? why replacing cat 5 with cat 6 ?

For the simple reason that the other answers provided will not solve CRC errors. There may be something wrong with the cable, including opens/shorts, breaks, attenuation, etc., so replacing it will work.
