Juniper Ethernet Switches Review

Pros and cons of both Cisco and Juniper configs, but you can see the benefit of why they organized it the way they did

After being primarily a Cisco user for many years, I find the switch to Juniper refreshing. The CLI is intuitive and I appreciate the hierarchy of the various configuration groups to be much more organized. I also think it is better with regard to config checking, and ensuring that the items entered into the config work with the rest of the config. For example if you happen to forget a line in a policy, or make an error in referencing a particular object, it will not let you commit the config. I know there are pros and cons of both configs, but once you get used to Juniper, you can see the benefit of why they organized it the way they did.

Regarding the comparison between Juniper and Cisco Ethernet Switches, what is your opinion about rollbacks? There can be situations when somebody makes a mistake.

Hi, well to your point about rollbacks, the benefits of this feature are quite obvious in that they provide a fail safe mechanism should your changes inadvertently isolate you from a remote device due to some unforeseen error/mistake (it happens!).
I often hear people compare this age old Junos feature to Cisco's "reload in|at x" command, however if the difference isn't already obvious, that command results is a device reload, whereas Junos rollbacks do not. Picture a scenario whereby your action isolates you from a remote device yet that device is still carrying production traffic loads. In this scenario, the user of rollback would be able to regain access to the device without impact to traffic through the device, whereas the user of the reload command would see an outage. Consider a worst case scenario whereby the device fails to complete its boot cycle and there my friend you have hell on your hands. May as well pack your stuff into a box and grab your coat at that point.

Junos OS is extremely flexible and easy to pick up.
What I like most about this solution is that it is secure.
The most valuable feature is that the CLI is the same on all of the Juniper devices, including routers, switches, and firewalls.
The ease of management through the command line interface is very good.
Juniper is the best when it comes to the core layer.
The scalability is excellent. It's one of the aspects of the solution that is quite good.
The GUI interface distinguishes it from other vendors and makes it easy to operate.
