In addition, it also gives you the ability to use routing, switching, and firewall functions within a single platform, which is really cost-effective for the end customer. Another thing I like about Junos is the JTAC support, which is cost-effective compared to other vendors and efficient in support. **What do you dislike about Junos OS?** Based on my experience, the response time for the GUI is a little bit slow. **Recommendations to others considering Junos OS:** If you are looking for a single device that is capable of handling routing, switching, and firewall functions, my recommendation is to go for Junos OS. With Junos OS, you can have all those capabilities within a single platform, which will be very cost-effective. As a system integrator, Junos OS's multiple features in a single platform help me win a lot of customers due to its cost-effective nature. It also provides a great configuration management feature by saving copies of your last few configuration changes, which you can use in case of a rollback and helps you track changes. In terms of device administration, it provides a GUI, so engineers don't need to be experts on the CLI. **What problems is Junos OS solving and how is that benefiting you?** I was able to use the Junos proxy-arp feature to hide my internal network from exposure to other parties to improve security. By using a single product, I was able to implement routing, switching, and firewall protection, which was cost-effective for the end customer and reduced the number of hops packets should travel, eventually saving a few milliseconds for the end user. ### 18.

Sometimes an uphill battle convincing them it's just as, if not better in certain situations. **Recommendations to others considering Junos OS:** Excellent product. Excellent sources of literature out there that will help you familiarize yourself with it. Such as CBT Nuggets, Junos Genius, O'Reilly books. Even if your primary vendor is Cisco, it's worth taking a look even if just for the next generation firewall features. The J-Web and CLI are very forgiving in terms of temporary commits of the configuration that if unconfirmed, will roll you back to the last working configuration (in the case you lost connectivity to your device due to a mis-configuration). **What problems is Junos OS solving and how is that benefiting you?** Managing firewalling, routing and switching devices. ### 34.
