Juniper EX4300 1 Gigabit Ethernet (1GbE) switches

EX4300 1 Gigabit Ethernet (1GbE) switches are compact, fixed-configuration platforms that can be deployed as standalone systems or as part of a Virtual Chassis, Virtual Chassis Fabric, or Junos Fusion switching architecture, satisfying a variety

Features

Field-Proven Juniper Technology

A carrier-class architecture, coupled with the Junos OS, enables EX Series switches to provide carrier-class reliability for every application.

Security Risk Management

Security risk management integrates Unified Access Control (UAC) to help EX Series switches dynamically deliver network protection, guest access, and identity-based quality of service (QoS).

Wire-Speed Performance

Wire-speed performance at high 1GbE, 10GbE, and 40GbE port densities dramatically simplifies network topologies and operations.

Eight QoS Queues

Eight QoS queues per switch port ensure proper prioritization of voice, video, and multiple levels of data traffic, with room to converge other networks, such as building automation and video security systems.

Innovative Switch Design

Innovative, cost-effective switch design enables new architectures that reduce cost and complexity, while unified management and automation tools consolidate system monitoring.

Virtual Chassis

Virtual Chassis technology allows multiple interconnected switches to operate as a single logical device, reducing operational expenses and simplifying management.

Near Line-Rate Encryption

Support for IEEE 802.1ae Media Access Control Security (MACsec) for link-layer data confidentiality, data integrity, and data origin authentication enables 88 Gbps of near line-rate, hardware-based traffic encryption on all 1GbE and 10GbE ports.
