Features & Benefits
Juniper Mist Wired Assurance
Quickly claim, configure, and troubleshoot switches with Mist’s AI-powered cloud. Gain visibility into device performance and health metrics through telemetry, enabling proactive issue resolution and improved user experiences.
Virtual Chassis
Interconnect up to 10 EX4300 and/or EX4600 switches to form a single logical device. This reduces operational overhead and supports pay-as-you-grow scalability in 1GbE, 10GbE, and 40GbE environments.
MACsec Support
EX4300 switches support IEEE 802.1ae MACsec for link-layer data confidentiality, integrity, and origin authentication. AES256 encryption across all access and uplink ports enhances security against unauthorized access.
12 QoS Queues
With 12 queues per port (8 unicast, 4 multicast), the EX4300 enables granular traffic prioritization, ensuring consistent quality for data, voice, and video applications.
