EDIT - 5 Jun 2015:
Thank you very much for an outstanding redesign. I un-downvoted, and like the following:
The router hockey-puck is a home run; great re-use of the puck as the letter "O". Simple. Jammin. Bravo.
Incorporating a network diagram into the background is a nice touch; although it's practically invisible with such a small image. I'm ...
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.
Advanced routing protocols like BGP, OSPF, IS-IS, VXLAN and EVPN on platforms without a paid support option (like Quagga, Mikrotik, FRR).
To me it feels 'wrong' that questions about these protocols, which this people on SE should be able to answer best, are considered off topic only based on the fact that there's no commercial support.
Currently off topic, ...
Network Design –
This category deals with how to design networks with on-topic network infrastructure. Assuming there are multiple network infrastructure technologies or implementation choices which can achieve the same design goals, questions about the nuances or implications of those technologies are on-topic.
For example, a valid Network Design ...
Enterprise/Service Provider Networks –
Questions one would encounter while operating, maintaining, purchasing, or managing an enterprise / service provider network. The question should be about the operation of your own network.
Enterprise, in this case, means a "business organization", which could be large or small.
Q: BGP - Better Enterprsie ...
Cloud-based networking, such as Amazon VPC configuration, NAT gateways, VPN configurations, BGP routing, load balancing, etc. Also Azure virtual networking, and similar offerings by other cloud providers.
Admittedly, there will be overlap with questions on the basic compute and application services these vendors offer, and those would best be answered on ...
I would vote that yes, config examples are on topic/welcome.
They are the type of question that is easily answerable in SE's Q/A format, and the type of questions that would drive search engine traffic our way.
The theoretical questions can sometimes lead into more of a discussion, instead of a cold hard "yes/no" or "this is how to do xyz". Which, to my ...
I would exclude home networks and strictly consumer devices (SOHO/business lines would be acceptable - but including CPE devices, which you often have no control over), and some small businesses. I would draw the line at "is it managed by an IT person." Whether this is full time or part time employee of the business or a consultant/contractor.
If you are a product representatives here to provide helpful technical support, we actually welcome and encourage posts directly from the source:
Using Network Engineering SE for Product Support
But if you find yourself recommending a product at every opportunity the subject comes up, you are likely here for the wrong reason. If you are posting good, ...
Questions about Unix / Linux Servers which are running Network Protocols or a Firewall –
Questions about firewalling or network protocols such as OSPF running on linux / unix servers... to qualify under this category:
The system must not be purpose-built by a vendor specifically for routing / switching / firewall purposes
The system must not have ...
Tools used by Network Engineers -
Questions about tools specific to Network engineering.
Q: Wireshark filters for OSPF Link State ID
Q: Why don't iperf, scamper and path MTU discovery packet captures agree on the path's MTU?
Q: NMS with advanced user management
Q: Monitoring Network Traffic
Q: Network monitoring and mapping software
The "avoid trivial edits" guidance is designed to keep otherwise well-meaning user from annoying everyone with endless, overly-pedantic changes that bump every post with trivial "activity." It's a bit user-hostile to have someone micro-editing every post; so we ask that most punctuation and semantic changes be accompanied by substantive changes that actually ...
Model/Product Line Features/Differences –
Features supported in the different models of a given product line, with different software versions, licenses, etc.
Q: What is the difference between all the switching modes on 6500/7600?
Q: What's the difference between CRS-1 and CRS-3
"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".
Q: Problems Connecting Catalyst 2960G to ...
Services that are required for normal operation of a network such as DHCP, DNS, RADIUS, etc.
Currently mostly off topic (unless on a platform such as IOS), and should be on topic.
Other related meta discussions: here, here, and here.
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 ...
Absolutely, these should be on topic. Please, this is not at all what is meant by "too localized." This close reason is being severely reworked because of these misunderstandings (more on that soon) — but it almost never makes sense to close a question because it pertains to a specific product.
Yes, questions about the products used in this subject ...
These are certainly interesting discussions in their own right — roundtable discussions which are fun to bandy about with your colleagues; they may even be educational — but frankly, this isn't what we do.
Take a look at the new /about page that lays out the purpose of having this site in the first place:
About Network Engineering SE
We get a ...
Network Protocols' Design/Theory –
Network protocol questions, like 'Why does Cisco's bgp process pack update packets in path attribute groups like this?' or ' Why does OSPF use this next hop address for these external LSAs?'
Application level protocols (example, host / server protocols above the TCP / UDP / ICMP PDUs) are explicitly off topic.
Unfortunately, soliciting users within our existing sites would not be appropriate. Unless a particular question has been deemed off topic for that site, you should not solicit content or users like that.
I can appreciate your need to find a community for your site, but with the number of sites vying for attention, it would simply become untenable to allow ...
In my mind, that would depend on the context.
If it is iptables running on a Linux box being used as a router or firewall on the network? Yes, it is on topic.
If it is iptables running on a Linux box and users can't access my website? No, it is better servered at SF or Unix & Linux.
If Lab software is part of the Network Engineering landscape, then absolutely these questions should be on topic here. As a matter of fact, the developers of these applications tend to have communities of their own, and these special interest groups have become a huge source of excellent questions and avid, supporting communities on a lot of sites. If these ...
Downside first: T-Ball questions are probably not of interest to many (a majority?) of our power users. So having more of them would, basically, add more noise. But I don't think this negative point is a deal-breaker.
On the upside...
– This does a lot to make people (people new to this stack) feel welcome if we all respond positively.
Clarification of "protocols above L4 in the OSI model are off-topic" to specifically mention routing and tunnelling protocols, which should all be on-topic.
L2TP is on top of UDP
BGP is on top of TCP
I don't know that anyone would disagree: I'm just trying to make the rules clearer.
We should NOT allow education questions of any kind, be they certification questions or degree questions.
I really do enjoy questions like this, but I think they belong in chat instead of on the main site.
The answers to these questions are likely to change quickly. Desired degrees and certifications could change based on the job market and a person's ...
