Yes, I think physical cabling would be on-topic We've had some questions regarding physical cabling. The ones which were closed would remain off-topic (home networking, vague, etc) even if physical cabling were on topic. That's good; I'm saying it seems we are already allowing physical cabling.

"Prosumer" Networking Gear – Questions regarding products that aren't exactly "consumer" grade, because they have the option for a token support contract. They are also a little too cheap to be widely used and understood - i.e. "48-port Netgear" switch, such as the "Netgear Prosafe 48-port GS718TS". Examples: Q: Problems Connecting Catalyst 2960G to ...

Lab Scenario: Questions about a lab scenario involving equipment we normally consider valid If you're studying for the CCNP (or another networking certification) at home / work and want to ask why a lab scenario you are building is broken, or need help configuring something; these questions should be on-topic. Even though lab questions are on-topic, we ...

Since this is a forum for professional networking, I consider helping people to bypass network policies (for a network over which they have no control) to be unethical. I have to think how I would feel if that were my network since an anonymous OP may actually be a user on my network. Questions related to bypassing network security or policies, except ...

TL;DR: No. More complete answer in response to comments by this user. Tomato USB based Router - Enterprise features at fraction of price. Just because a product has "Enterprise features" doesn't make it an enterprise class of device. Certainly either of these firmwares may be arguably better than vendor provided firmwares, but that doesn't make them ...

Certification questions have been deemed off-topic since before beta. In my mind, there is little difference between certification and homework questions, and they should be off topic whether they are multiple choice or not. Personally, homework questions are a bit worse to me as I am not here to do some college student's homework for them. Getting an ...

Production Troubleshooting Scenarios: Troubleshooting questions can be challenging to handle well on Stack Exchange, because they are so situational. However, they are welcome Please back up answers with facts from the question Please do not answer with speculation about the problem. If something is unclear, ask in a comment.

I want to add to Brett's position on this, which is: historical questions are valid as long as there is a way to give a concise, accurate and fact based answer. We have to draw a line somewhere. Historical questions, like all others, should exhibit a compelling reason to be answered on NE. I could come up with a long list of trivia questions, which ...

> Why are recommendations or polls off-topic? Stack Exchange strives to be an authoritative resource for Questions and Answers. Polls and recommendations wind up being a Repository (of knowledge), which is fundamentally at odds with the structure of SE. Also note that shopping questions are a subset of recommendations (i.e. someone is asking for a product ...

What is On-Topic Are there any OSI layer4 (or above) network protocol questions which are on-topic? Yes, this is even hinted at in the help center: If the question is about the design, theory or even simply using features of protocols used to operate a network, then the question should be on-topic. Protocols used to operate a network include (but ...

I mostly like YLearn's answer; indeed there are some things about homework questions that are risky: First, the site is for professional network engineers. The last thing we want is a flood of undergrad (or lower) questions that are trivial for any aspiring CCNA. Physics.SE already has this problem; they started accepting homework questions, and now there ...

Closing Questions Historical context: Usenet .moderated Newsgroups If you've been on any of the Usenet .moderated newsgroups, all posts are reviewed first, and then evaluated for acceptance; the goal is to keep problem discussions from arising. .moderated groups take a default-deny stance, and the question is permitted if it's judged as appropriate. Stack ...

Interview questions are generally being used to gauge two things: a level of knowledge and how a person thinks. In the first case, I view this somewhat like test/homework questions (which we don't allow). So my stance personally is about the same as my stance on homework questions. In summary, the actual interview question is a no, but questions about the ...

I think physical layer is clearly 'on topic'. Its right there at the beginning of the OSI model and its where most troubleshooting begins. There are also design discussions such as top-of-rack verse middle-of-row data center designs, stack-able switches verse chassis. etc

Perhaps the best answer to the "question" is to provide some pointers to complex questions that have exemplary documentation. I would like to hold up these questions as examples of how well you could document your problem so that others can effectively and accurately assist.

Definitely on topic. While generic questions like UTP wiring may seem mundane, think about topics around modular patching, WDM, light switching, etc.

Networking (and IT in general) is a rapidly developing technology, with new devices, concepts and features being developed practically every day. It’s easy to get confused by various terms, especially if you are new to the field or even new to a specific technology. When a new feature or technology is developed, the people who developed it naturally want to ...

Are host virtualization design or troubleshooting questions on-topic? Short answer: No. Host virtualization solutions exist to turn one physical server into many virtual servers. The community overwhelmingly voted purely server questions off-topic . Could we ever make exceptions for VM questions? Of course, this meta Q&A is intended to cover run-of-...

I have made my views fairly clear before on this subject in this previous answer about homework questions or this answer about interview questions, but let my provide by viewpoint again with perhaps a bit more detail. My belief is that homework questions should be off topic, for two reasons: I do not give my time to this community to do someone else's ...

I understand what you are saying. I certainly don't want this site to be completely turned into a "Do my homework for me" site, but, as in the question to which you refer, I think it may be OK to, once in a while, help someone who has put in a lot of the work and shows that. The other side of that is that, suddenly, this site is flooded with homework ...

The industry is blurring the lines more and more between "Server Admins" and "Networking Admins", with things like SDN being very relevant for both Server and Network techs to understand and factor when designing solutions. I think if the topic is purely about Virtualization... which is to say, if we could replace the words "VM" with "Server" and the ...

I feel that historical questions are valid here as long as there is a way to give a concise, accurate, and fact based answer. Many questions about the hows/whys of the early internet are well documented through the many RFCs, as well as through interviews with the primary sources who were involved. However, there are questions that may not be easily ...
