Description

Juniper Switches

Optimize user and application experiences while improving networking economics with cloud-grade, high-density Ethernet switching across your data center, campus, and branch locations. Juniper switches deliver agile, reliable, and scalable networks with AI-powered automation and insights.

switches are cloud-ready, high-performance access and distribution/core-layer devices for enterprise branch, campus, and data center networks. With the EX Series, wired access networks don’t have to be complex—you can reduce risk and cost without compromising performance, quality, or innovation. Easily onboard, configure, and manage the switches and operate campus fabrics at scale with the Juniper Mist Cloud. Combine the EX switches with Juniper’s Wi-Fi portfolio for a unified wired and wireless solution, driven by Mist AI, that delivers simple and secure connectivity at scale.

Features and Benefits

Managing AI-Driven Campus Fabric with the Juniper Mist Cloud

Juniper Mist Wired Assurance brings cloud management and Mist AI to campus fabric. It sets a new standard moving away from traditional network management towards AI-driven operations, while delivering better experiences to connected devices. The Juniper Mist Cloud streamlines deployment and management of campus fabric architectures by allowing:

Automated deployment and zero touch deployment
Anomaly detection
Root cause analysis

High Availability Features

To avoid the complexities of the Spanning Tree Protocol (STP) without sacrificing network resiliency, the EX2300 employs a redundant trunk group (RTG) to provide the necessary port redundancy and simplify switch configuration. It also supports cross-member link aggregation, which allows redundant link aggregation connections between devices in a single Virtual Chassis configuration, providing an additional level of reliability and availability.
