Hi,
my output of command :
ethtool -g em1
Ring parameters for em1:
Pre-set maximums:
RX: 4096
RX Mini: 0
RX Jumbo: 0
TX: 4096
Current hardware settings:
RX: 1024
RX Mini: 0
RX Jumbo: 0
TX: 1024
before current value for RX and TX are 256 and i increased it by
1024 for both RX and TX. But still we having packet loss on
interface.
How to verify that buffer full for RX and TX?
Regards,
Benjo
What does ethtool -g em1 say? A very common reason of
dropping packets is that the rx and tx buffers have been full. In
this case, you can increase the count with ethtool -G switch and
check again.
