Hi, everyone!
We have a strange problem in a customer environment. There are rx_length_errors constantly increasing on BPEth0 and BPEth1 interfaces. We can see that there are no rx_undersize or rx_oversize in the output of ethtool -S BPEthX.
#ethtool -S BPEth1 | grep 'port.rx_undersize\|port.rx_oversize\|port.rx_length_erro
rx_length_errors: 172188
port.rx_length_errors: 172188
port.rx_undersize: 0
port.rx_oversize: 0
#ethtool -S BPEth1 | grep 'port.rx_undersize\|port.rx_oversize\|port.rx_length_erro
rx_length_errors: 172192
port.rx_length_errors: 172192
port.rx_undersize: 0
port.rx_oversize: 0
I have tried to capture traffic on BPEthX interface of our lab Chassis 64000. 99% of traffic is CCP and ARPs. There is no production traffic in tpcdump or cppcap. It looks like SecureXL doing the same thing as with VSX wrpj interfaces.
What is the procedure to capture all frames which are passing via back-plane interfaces?
What may be the reason for the strange rx_length_errors?
