Cisco IOS is probably a universal standard and one that people usually use in basic network classes. Arista Extensible Operating System (EOS) is so similar to Cisco IOS that the commands to do basic configuration are nearly identical. Arista Extensible Operating System (EOS) …
It is well suited in environments that have a low change rate. Once configured, the Arista Extensible Operating System (EOS) is rock solid but changes can be a little cumbersome. The good news is that the learning curve of the Arista Extensible Operating System (EOS) commands is relative short. Many of the commands are similar to other vendors and so expertise in one command set should easily translate to Arista Extensible Operating System (EOS). Our network admins had no problem making the adjustment.
iOS works well when you want solid control over institutionally-owned devices. This generally works best when you play by Apple's rules and buy through them and use Apple School/Business Manager - so if you're going for a BYOD model, this probably isn't the way to do [it]. There is a wide variety of management tools, but bear the costs of each in mind.
Manage - Arista Extensible Operating System (EOS) is comprehensive enough that all of the commands are present to manage the device and take advantage of all of the unique features.
Scale - A single command set across multiple pieces of hardware allow us to script changes and deploy hardware easily.
Update - Arista Extensible Operating System (EOS) updates happen seamlessly and often don't require rebooting the underlying hardware thanks to it's module-by-module approach.
There are "assumptions" for lack of a better word that are baked into the Arista Extensible Operating System (EOS). While many would be considered best practice, there are others that require a great deal of workarounds for specific environments.
Some details about hardware state are hard to get inside the command structure. There aren't summarized views for many of the more routine queries.
Logging - It is difficult to output logging to a SIEM collector and also let logs remain on the device.
Many of the commands mimic or are identical to vendor commands. This makes the software incredibly easy to learn and use. My one complaint is that sometimes the details and summaries don't include a lot of details so it takes multiple commands to get all the information. Detailed output doesn't always include data included in the summary. This is relatively minor and may just be a personal preference
In all likelihood, common users will either already have experience with iOS on their iPhones, or will pick it up quickly. The UI is generally simple and mostly visual. Power users, on the other hand, may feel constrained by the inherent limitations built-in. Root access, terminal commands, and deep customization are not really to be found here.
Lots of help articles online for just about everything under the sun. I have never personally had to engage Apple's support team to comment on their helpfulness.
Cisco IOS is probably a universal standard and one that people usually use in basic network classes. Arista Extensible Operating System (EOS) is so similar to Cisco IOS that the commands to do basic configuration are nearly identical. Arista Extensible Operating System (EOS) includes a lot more detail on reporting but you do have to dig for it. Arista Extensible Operating System (EOS) also allows for much more granular configuration.
The software updates have a wide coverage for iPhone models and I love updating software for additional features and/or improved software stability. It has also genuine feel of the phones they offer. Easier to set up and use. It helps me do more productive tasks. If I have the latest phone model, I would have additional software advantages that are already included in my OS.
No Training Budget Needed - Command set is similar to other vendors and it required no specialized training.
Reduced Downtime - Many Arista Extensible Operating System (EOS) updates can happen without rebooting the underlying hardware meaning that downtime is reduced. This makes EVERYONE happy.
Few Bugs - There are very few bugs in the Arista Extensible Operating System (EOS) production code thanks to great Q/A work by Arista.
