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

Juniper Mist Wired Assurance
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.
Virtual Chassis
With Virtual Chassis technology, up to ten interconnected EX3400 switches operate as a single logical device, reducing operational expenses and simplifying management.
MACsec Support
EX3400 switches support IEEE 802.1ae MACsec, providing support for link-layer data confidentiality, data integrity, and data origin authentication.
12 QoS Queues
12 QoS queues (8 unicast and 4 multicast) per switch port enable multilevel, end-to-end traffic prioritization.



Product Description

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. The fixed-configuration EX3400 supports a number of key features, including:

    • 24-port and 48-port models with and without Power over Ethernet (PoE/PoE+) are for campus wiring closet deployments.
    • Cloud-ready and zero-touch provisioning (ZTP)-enabled for Juniper Mist Wired Assurance
    • Data center-optimized cooling options offer both front-to-back and back-to-front airflows, making the EX3400 suitable for GbE data center access deployments.
    • Two redundant, field-replaceable power supplies each provide up to 920 watts of power.
    • 24-port data center models are included for metro deployments.
    • Four dual-mode (GbE/10GbE) small form-factor pluggable transceiver (SFP/SFP+) uplink ports and two 40GbE QSFP+ ports are available.
    • Uplink ports can be configured as Virtual Chassis interfaces and connected via standard 10GbE/40GbE optic interfaces (40GbE uplink ports are preconfigured by default as Virtual Chassis ports).
    • Comprehensive Layer 2 functionality with RIP and static routing is provided.
    • A compact, 13.8-inch deep 1 U form factor supports flexible deployment options.
    • An easy-to-manage solution includes centralized software upgrades.
    • Support is available for the same consistent modular Juniper Networks Junos operating system control plane feature implementation used by all other Juniper fixed-configuration Juniper Networks EX Series Ethernet Switches.
    • Support is provided for Layer 3 (OSPF v2, IGMP v1/v2/v3, PIM, VRRP, BFD, virtual router) via an enhanced feature license (optional license required).
    • Support is available for IPv6 management, including neighbor discovery, stateless auto configuration, telnet, SSH, DNS, system log, NTP, ping, traceroute, ACL, CoS static routing, and RIPng.
    • IPv6 routing features (OSPFv3, virtual router support for unicast, VRRPv6, PIM, MLDv1/v2) are supported via an enhanced feature license.
    • Support is available for Border Gateway Protocol (BGP), multiprotocol BGP (MBGP), and Intermediate System-to-Intermediate System (IS-IS) via an optional Advanced Feature license.

Energy Efficient Ethernet (EEE) capability is provided.
