Cisco Interface Rates are typically buried inside of the show interfaces command output. However there are ways to filter in Cisco IOs and it is similar to the Linux CLI utility known as grep.

Have you ever needed to show a specific port’s rate – or show all ports at the same time? I know for me it’s hard to read all that output at the same time. It would be nice if there were a command just for showing interface rates but instead we have to filter out some of the output given to us by the stock IOS commands.

Here is a special little cli magic that I use to show all interfaces input-output rates at the same time:

lab-cisco# show interfaces | in line_proto|input_ra|output_rate

This uses the tool include which is similar to the grep tool in Linux. I call it grep for Cisco IOS.
