Like netstat, the -n option is used to display numeric information only.

Linux show mac address table manual#
The manual page for route also states that it is obsolete and has been replaced by the ip route command previously mentioned, again as this is still used, here’s an example of it.

Some devices can have one, but not the other. This is commonly used with the -n option, which will only show numerical addresses rather than performing any sort of name resolution. Netstat combined with the -r option will display the kernel routing tables. To tie together the data link (Layer 2) layer and the network (Layer 3) layer, a mechanism must exist that maps data-link layer addressing to network layer addressing this mechanism is ARP. The Address Resolution Protocol (ARP), as you might guess, is designed for resolving addresses. Nevertheless as it is still widely used, we have included it here. Address Resolution Protocol (ARP) Tables. While this is a popular way of printing out routing information in Linux, netstat is actually deprecated and replaced instead with ip route – it even says so in the manual page. While this is the current recommended method of printing out the routing table in Linux, you will see that the output doesn’t look as nice as older options.Ĭheck out our IP command examples for further information on how you can use this to display networking information. If you’re in a hurry you can also shorten this to ‘ip r’ which will print the same output. The current recommended way of printing the routing table in Linux is with the ip command followed by route, as demonstrated below. So these commands should be working on the popular distributions like Arch Linux, CentOS, Debian, Gentoo, RHEL, and Ubuntu. Therefore, it is good to know which tools can be used to query these details in a generic way. If you’re instead trying to create a new static route in Linux check out our guide here. Every Linux distribution is using its own way of configuring the network configuration details. Here are three different commands that you can use to print out the routing table in Linux. The routing table is used to show you where various different network subnets will be routed to.
