Terms of use
By using this site you accept these terms. If you do not accept them, please do not use the site.
What the site is
Polling Interval publishes articles, guides and calculators about network monitoring and related topics. Everything here is general information written to be useful, not professional advice for your particular network. Commands, configurations and numbers are checked when we publish them, but software changes, hardware differs and mistakes happen.
Use at your own risk
Test any command or configuration on a lab or non-production system first, keep backups, and follow your organization's change process. We are not responsible for outages, data loss or security problems that result from applying what you read here. The Netcalc tools show their formulas so you can check their results; verify anything that matters before you rely on it.
Copyright
The text, diagrams and images on this site belong to Polling Interval unless stated otherwise. You may quote short passages with a link back to the page. Code snippets and configuration examples in articles may be used freely in your own systems. Please do not republish whole articles or the field manual elsewhere.
Links and affiliate links
We link to other sites when they are useful. We do not control them and are not responsible for their content. Some links to shops are affiliate links that may earn us a commission; they are marked on the pages where they appear, and the privacy notice explains how they work. Product mentions are chosen on their merits, from specifications and published reviews.
Changes
We may update these terms; the date at the bottom shows the latest version. Questions go through the contact page.
