Virtual chassis technology enhances connectivity and simplifies management
Juniper EX series switches offer great technology, particularly their Virtual Chassis technology, which is an excellent feature for stacking switches and functions like a single virtual switch. The EX series provides a separation of control, management, and data planes, reducing the attack surface area, ensuring a lesser extent of vulnerability. The PoE budget is commendable, and they manage connectivity effectively.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Juniper Switches' best feature is its flexibility."
"The campus switches and access switches are the most valuable and simple to deploy for Virtual Chassis."
"You willuse almost every feature on every switch to some degree because the utility is valuable."
"It has features that allow us to go back to previous configurations."
"It is a scalable solution."
"It's pretty good as compared to other vendors."
"The Juniper Ethernet switch feature I find the most valuable is reliability."
"The most valuable feature is switching on our network."
"The tool is very configurable because it runs on a Linux operating system."
"The most valuable features of this solution are its functionality."
"From what I've been told, a valuable feature of Mellanox switches is they're quite user-friendly."
"It is a very easy-to-use product."
"The most valuable features of Mellanox Switches are the size, power consumption, and the vast amount of features."
"The most valuable features of Mellanox Switches are the powerful hardware and the software is open. They're using Linux operating system. You can do and install many things, and it performs well."
"The biggest advantage is that the vendor is the only one providing no-drop traffic."
 

Cons

"One potential drawback of the Juniper EX Series has been that those without experience using a command-line interface (CLI) may find it intimidating. However, Junos is working on improving this by offering tools, such as Juniper Mist with Wired Assurance and Apstra. Additionally, the graphical user interface (GUI) could be improved as it has been considered lackluster across the board in Junos."
"Support could be improved."
"Its distribution channel and the ease of availability should be improved."
"Juniper's support could be much better and faster."
"EX switches take too long to boot when we restart them for maintenance. We need to minimize downtime. Another issue is the command line interface. Juniper's commands are different from other switches, so it's hard to remember them."
"The only issue that we have with Juniper Ethernet Switches is the firmware because it is not stable."
"Juniper Ethernet Switches would be improved by upgrading the uplink port in EX2300 categories service from 10G to 25G."
"It was very difficult to get technical support, here in Egypt. There is no local support available."
"Mellanox Switches were easier before Nvidia bought Mellanox and then their new version of the operating system changed. They started with Ennui, and now they only use Linux. If they returned to their previous CLI it would be a good option for starters. The new CLI is more difficult to use but more powerful than the older one. It has its advantages."
"Sometimes, it can have some bugs from the past if I am an old user. However, it is stable now."
"If you compare this solution with Cisco, utilization in Cisco is more popular and it is more friendly."
"The scalability is working fine at the moment, but there's always room for improvement. As of right now, I don't know of any improvements to suggest."
"Mellanox Switches could improve by adding some features that can make it easier for integrating the switches in some managing and monitoring platforms, such as Elastic or similar software for monitoring data with the data center in a more holistic way."
"The configuration is a bit different from Cisco, and therefore, for me at least, there's a bit of a learning curve."
 

Pricing and Cost Advice

"For the QFX5000 Juniper switches, the price is about $10,000, but they would probably sell it for $1,000. Nobody can beat Juniper's pricing when it comes to switches. Juniper out-prices everybody, but they get you on the back end, maintenance, service port, and service contract."
"We don't need to pay for the solution's features."
"The price could be cheaper."
"The maintenance cost is approximately €2,000 ($2,200 USD) per year, including support, for our entire fleet."
"It's was $100,000 per year."
"Juniper Ethernet Switches are cheaper than Cisco or HP."
"We had a leakage in the support process and decided to end the product's life in order to purchase a new product with support. We did not renew product support as a result."
"You require the Junos Management Platform in order to manage the switches and you need to purchase the Juniper Ethernet Switches."
"There is a license to use the switch ports of Mellanox Switches."
"The price of Mellanox Switches is reasonable compared to other solutions. The price and quality ratio was very good. There is a one-time license purchase that is needed."
"The pricing is very competitive. The licensing costs are fine."
"It's an open-source solution."

Benefits of Juniper vs Cisco
Both are decent products. I prefer Juniper for the following reasons: 1) Cleaner separation of data plane from control plane. Higher end Cisco devices are better at this but most of the lower end products still seem to be more integrated than I like. 2) The Hierarchical config design means I can…
