EX3400 Ethernet Switches

EX3400 Ethernet Switches are a cost-effective solution for today’s most demanding converged data, voice, and video enterprise access networks. The compact, fixed-configuration 1U devices offer levels of performance and management previously available only with high-end access switches.

The EX3400 is cloud-ready and ZTP-enabled, so you can onboard, configure, and manage it with Juniper Mist™ Wired Assurance for improved connected-device experiences. In addition, the Juniper Mist Cloud streamlines deploying and managing your campus fabric, while Mist AI simplifies operations and improves visibility into the performance of connected devices. EX3400 switches support Juniper’s Virtual Chassis technology for interconnecting up to 10 switches that can be managed as a single logical device.

Features + Benefits

Claim, configure, and troubleshoot switches with a few clicks. Wired Assurance delivers better experiences for connected devices through AI-powered automation and service-level expectations (SLEs) with Mist’s AI engine and microservices cloud.

The EX Switches provide rich streaming telemetry data to enable the insights for switch health metrics and anomaly detection. Streamline IT operations, reduce mean time to repair, and deliver optimized experiences across wired and wireless.

With Virtual Chassis technology, up to ten interconnected EX3400 switches operate as a single logical device, reducing operational expenses and simplifying management.

The Juniper Networks® EX3400 Ethernet Switch with Juniper Networks Virtual Chassis technology provides enterprises with the flexibility and ease of management that previously was only available with higher-end access switches.

EX3400 switches support IEEE 802.1ae MACsec, providing support for link-layer data confidentiality, data integrity, and data origin authentication.

The MACsec feature enables the EX3400 to support 88 Gbps of near line-rate hardware-based traffic encryption on all 1GbE and 10GbE ports.

12 QoS queues (8 unicast and 4 multicast) per switch port enable multilevel, end-to-end traffic prioritization.

EX3400 supports rich quality-of-service (QoS) functionality for prioritizing data, voice, and video traffic.
