Why are packet drops reported in Ifconfig not reflected in ethtool?
The ethtool statistics should be favoured over those of ifconfig . The dropped counter in ifconfig was originally intended to log protocol-only drops, such as a protocol handler being unable to allocate memory, but has since been obscured by various drivers adding their statistics in no standard way to these counters.
What is RX packets in Ifconfig?
RX packets is a total number of packets received. RX errors shows a total number of packets received with error. This includes too-long-frames errors, ring-buffer overflow errors, CRC errors, frame alignment errors, fifo overruns, and missed packets.
How do you test if packets are being dropped?
Diagnosing Packet Loss
- Run a Traceroute to the remote endpoint to determine the router hops to the destination.
- Perform a ping test to each of these router hops to see if the network is stable to a specific location, or if loss starts to occur at or beyond a certain point.
What does Rx drop mean?
When packets are being dropped on a computer, they’re being dropped for a reason. a packet enters the network stack of your computer ( RX ) (say on port 8000). It gets dropped before the application listening on port 8000 receives it. you send a packet ( TX ). Before it makes it out of your computer, it gets dropped.
What is an ifconfig dropped RX packet in Linux?
For our case with the same issue with RX dropping packets due to IP address value is larger than Netmask value (ex: 17.229.24. 266 vs 255 .255.255.0, 266 > 255) Thanks for contributing an answer to Unix & Linux Stack Exchange!
