The guides and explanations on this site are general information. They are not a recommendation for your specific situation, because we have not seen it.
General information, not advice
Networks and IT decisions depend on details — the building, the equipment already in place, how many people use it and what for. An article cannot know any of that. Acting on general guidance without checking it against your own circumstances is at your own risk, and we are happy to look at your situation properly if you ask.
Accuracy
We write this material carefully and correct it when we find it wrong. Technology moves, though, and a page that was accurate when written may not stay accurate. We do not warrant that everything here is current or complete.
Products and prices
Where we mention specific products, availability and pricing change frequently and are confirmed only in a written quote.
External links
We sometimes link to manufacturers, documentation or other resources. Those sites are not ours, and a link is not an endorsement of everything on them.
Professional certifications
Where we refer to Cisco certification, that describes the qualification held by our own staff. It does not mean this site or its content is endorsed by, affiliated with, or produced in partnership with Cisco Systems.
