Linux display summary of protocol-level statistics for all network interfaces

To display a summary of protocol-level statistics for all network interfaces on a Linux system, you can use the ip command.

For example, to display a summary of TCP statistics, you can use the following command:

ip -s -s neigh show

This will show the number of packets sent and received, as well as the number of errors and collisions for each network interface.

You can also use the netstat command to display similar information. For example, to display a summary of TCP statistics, you can use the following command:

netstat -s

This will show the total number of packets sent and received, as well as the number of errors and collisions for all network interfaces.

Alternatively, you can use the ifconfig command to display detailed information about each network interface, including the number of packets sent and received, the number of errors and collisions, and the current status of the interface. To display this information, you can use the following command:

ifconfig

This will show detailed information about all network interfaces on the system.
