Terms
Configuration advice applied to a live network can take it down. Read this before you paste anything into a production device.

Use at your own risk
Everything here is published in good faith and tested on the equipment named in each article. It is not a substitute for your own testing. Commands that are safe on one device, one version and one topology can lock you out of another. Test in a lab or a maintenance window, keep a recovery path — out-of-band access or physical access — and have a configuration backup you have actually restored from at least once.
Manoranjan Behera accepts no liability for loss, outage, or damage arising from anything published on codesecho.com. If you cannot afford for a device to go offline, do not try it on that device.
Security content
Articles describe weaknesses in equipment so that the people who run it can close them. They are written for defenders. Applying any of it to a system you are not authorised to administer is illegal in most jurisdictions and is not what this material is for.
Accuracy and versions
Each article records the software version it was verified on. Vendors change defaults and behaviour between releases, and an article that was correct on one version can become wrong on the next. Check the verification stamp against what you are running.
Copyright
Articles, screenshots and diagrams are © 2026Manoranjan Behera. Quote a paragraph or two with a link back — that is welcome. Republishing whole articles, with or without attribution, is not.
Configuration snippets and scripts published here may be used freely in your own environment, commercial or otherwise, with no attribution required.
