How to show dropped packets per interface on Linux

To show the number of dropped packets on a network interface on a Linux machine, you can use the ifconfig command. This command allows you to view and configure network interface parameters.

To view the number of dropped packets on a network interface, you can use the following command:

ifconfig <interface> | grep "RX drop"

Replace <interface> with the name of the network interface you want to check. For example, to view the number of dropped packets on the eth0 interface, you can use the following command:

ifconfig eth0 | grep "RX drop"

This will print a line like RX dropped:0, which indicates the number of dropped packets on the interface.

You can also use the netstat command to view the number of dropped packets on a network interface. This command allows you to view network statistics, including the number of dropped packets.

To view the number of dropped packets on a network interface using netstat, you can use the following command:

netstat -i | grep <interface>

Replace <interface> with the name of the network interface you want to check. This will print a line like eth0: 123456 0 123456 0 0 0 0, which includes the number of dropped packets on the interface.

Note that the specific command and options for viewing dropped packets may vary depending on your Linux distribution and the tools it provides. Consult the documentation for your specific distribution for more information.
