Have tried changing cable, no change, still same error rate (aprox 150 errors per min).

When I try to reproduce this with iperf, I can do 20 connections with 750Mbps total throughput (i.e. 7.5x higher), and it does not crash the network. The sending node calculates the FCS number using an algorithm called cyclic redundancy checking (CRC).

By submitting my Email address I confirm that I have read and accepted the Terms of Use and Declaration of Consent. The disadvantage is that data frames with FCS errors may be propagated to the next hop because transmission out of the switch begins before the FCS error is detected. When the switch receives a frame, it runs its own checksum on the frame and compares the resulting CRC value to the value in the Ethernet frame. http://supportcontent.checkpoint.com/solutions?id=sk61922 As with other FCS errors, alignment errors most often result from noise on the cabling, although hardware problems in network interface cards or other network hardware can also cause them.

No problem! Scorpeo mentioned that a speed or duplex mismatch could cause the issue. In other words, the length of a frame in bits should always be evenly divisible by eight.

If it does then it points to whatever is connected to it. 0 Message Author Comment by:RichardHills2012-10-03 Will probably need to wait till tonight to reset speed and test further. DO NOT share it with anyone outside Check Point.

Best way to sort it is unplug it all except a single calbe - wipe the error log and plug in onebyone and watch till the RX errors go up. hope this helps. 0 LVL 21 Overall: Level 21 Networking Hardware-Other 3 Message Active today Accepted Solution by:David Atkin2012-10-03 Hello, It could be the cable that is connected to that Unknown protocol errors. However, sometimes network ports are misconfigured as half-duplex.

Nodes that transmit Ethernet frames append an FCS number, which lets the receiving device determine if the packet is complete and correct upon arrival.
