Welcome!
Hello, and welcome to Wikipedia!

Someone using this IP address, 79.13.143.174, has made edits to Spanning Tree Protocol that do not conform to our policies and therefore have been reverted. For more information on this, see Wikipedia's policies on vandalism and limits on acceptable additions. If you did not do this, you may wish to consider [ getting a username] to avoid confusion with other editors. If you'd like to experiment with the syntax, please do so in the sandbox rather than in articles.

You don't have to log in to read or edit pages on Wikipedia, but creating an account is quick, free, requires no personal information, and has many benefits. Without a username, your IP address is used to identify you.

Some good links for newcomers are:
 * Help contents – the main help page.
 * Quick guide – a "cheatsheet" listing the main editing commands.
 * The five pillars of Wikipedia
 * Contributing to Wikipedia
 * Tutorial

Please sign your name on talk pages using four tildes (~&#126;); this will automatically produce your name and a timestamp. If you need help, check out Questions, ask the Help Desk, or place  on your talk page and someone will show up shortly to answer your questions.

Please do not add inappropriate external links to Wikipedia, as you did to CCNP. Wikipedia is not a collection of links, nor should it be used for advertising or promotion. Inappropriate links include, but are not limited to, links to personal websites, links to websites with which you are affiliated (whether as a link in article text, or a citation in an article), and links that attract visitors to a website or promote a product. See the external links guideline and spam guideline for further explanations. Because Wikipedia uses the nofollow attribute value, its external links are disregarded by most search engines. If you feel the link should be added to the page, please discuss it on the associated talk page rather than re-adding it. Thank you. &mdash; UncleBubba ( T @ C ) 04:21, 10 February 2021 (UTC)
