CRC is a polynomial function on the frame which returns a 4B number in Ethernet. You can help Wikipedia by expanding it Parameter. M. With no CRC errors on the VDSL (very high speed digital subscriber line) interface, packet loss is coming from deeper within the network, northbound of the DSLAM (Digital Subscriber Line Access Multiplexer). The sum of all errors that prevented the final transmission of datagrams out of the interface that is being examined. This can be an early indication that there is too much noise on the line and in extreme situations can lead to loss of sync (disconnection with the exchange). This type of noise is very dirsruptive in digital data transmissions causing errors. If no CRC errors have occurred in the last 15 minutes, the CRC counter value will be zero. When logging into your router, you are often able to see these levels, measured in decibels or dB. Many CRC errors in a short period of time will show a noticeable reduction in throughput speed. On-peak hours, the noise increases as your provider’s DSLAM becomes crowded (people talking in the street) and the SNR margin gets worse. 1 255. This test also helps determine whether issues are coming from the equipment (CPE or DSLAM/DPU ports) or from the profile settings. You cannot post here or create a new thread or review on this forum. It doesn't necessarily mean there is a proble, just that the router is reporting the odd lost packet which is retransmitted that quick that you would never notice.
