Commenting configs

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi folks! So I wanted to rant about one of my pet peeves. That is command line configs and people not commenting them properly!

You see, regardless of what CLI you are using, whether it’s Cisco or HP or some other vendor. Commenting your config so another administrator coming along can understand your thought process is always a helpful thing.

Don’t get me wrong. You can still figure things out without the comments, but if you take the time to do it, you can save an administrator valuable time when they are troubleshooting something in an emergency situation.

This can be just as simple as naming vlans and interfaces so people understand how traffic is flowing on your network when they are looking through the config. It can even help you if you haven’t read your own config for a very long period of time. It can help jog your memory.

So be a friendly administrator and comment those configs!
