Architecture and Key Components

The EX4300 is a 1U device suitable for dense wiring closets and access switch locations where space and power are critical. It supports high-speed Virtual Chassis backplane connections via pre-configured 40GbE QSFP+ ports. For 1GbE access switches, these ports can also serve as uplinks to upstream aggregation devices. Front-panel uplink module options provide 1GbE or 10GbE ports for high-speed backbone or wiring closet connections. Multigigabit models offer choices of 4-port 10GbE SFP+ uplink modules or 2-port 40GbE QSFP+/2-port 100GbE QSFP28 uplink modules. Uplink modules can be installed without powering down the switch, allowing for flexible upgrades.

The 1GbE access EX4300 models feature a front-panel LCD for device setup, configuration rollback, alarm reporting, and factory reset. In Virtual Chassis configurations, this LCD displays the chassis slot number and RE status for quick identification and troubleshooting. Four integrated rear-panel 40GbE QSFP+ ports support EX4300 Virtual Chassis deployments with a 320Gbps backplane. EX4300 switches can be interconnected using standard DAC cables or optics for wiring closet or Top-of-Rack (TOR) data center applications.

Dedicated rear-panel RJ-45 ports are available for out-of-band management, and rear-panel USB ports facilitate easy Junos OS and configuration file uploads. Dedicated front-panel USB console ports and rear-panel RJ-45 console ports offer flexible out-of-band console options.

Virtual Chassis Technology

Virtual Chassis technology allows up to 10 EX4300 switches to be interconnected as a single logical device, supporting up to 480 10/100/1000BASE-T ports and up to 40 10GbE or 40 40GbE uplink ports. For mixed 1GbE and 10GbE access environments, EX4300s can interconnect with EX4600 enterprise campus and QFX5100 high-performance data center access switches. EX4300 Virtual Chassis configurations support a wide range of port densities and options for data center, campus, and branch deployments. Virtual Chassis connections can be configured using standard DAC or fiber optic cables over 40GbE or 10GbE ports. GbE copper or fiber ports do not support Virtual Chassis technology.

With multigigabit EX4300 models, Virtual Chassis technology enables up to 10 switches to interconnect using dedicated 40GbE ports, forming a single logical device supporting up to 240 10/100/1000BASE-T ports and 240 100/1000/2500/5000/10000BASE-T ports, plus up to 40 10GbE, 20 40GbE, or 20 100GbE uplink ports. Multigigabit EX4300s can also be part of a mixed-mode Virtual Chassis configuration with 1GbE EX4300 access switches, comprising up to 10 members.

Virtual Chassis Deployment in Campus Wiring Closets

For campus wiring closets, Virtual Chassis configurations can be extended over longer distances across multiple closets, floors, or buildings using standard QSFP+ optics over 40GbE ports (or 10GbE/40GbE for uplink connections), enabling flexible topologies. EX4300 fiber-based switches can also be used for campus aggregation or small core deployments.

Virtual Chassis Deployment in Data Centers

In data center deployments, Virtual Chassis configurations allow all EX4300 switches to be monitored and managed as a single device, enabling organizations to decouple endpoint logical grouping from physical topology and achieve more efficient resource utilization. Resilient topologies can be built using 40GbE DAC cables.

Features and Benefits

Chassis-Level High Availability

The EX4300 Ethernet Switch line provides high availability through dual power supplies and fans, GRES, Nonstop Bridging (NSB), and Nonstop Routing (NSR). In a Virtual Chassis configuration, each EX4300 switch can act as a routing engine. When two or more EX4300 switches are interconnected, they elect a master (active) and backup (hot-standby) RE. Integrated L2 and L3 GRES ensures uninterrupted access to applications, services, and IP communications in case of a primary RE failure. In a Virtual Chassis configuration, other member switches act as line cards and can take over if the master RE fails. This N+1 RE redundancy, combined with Junos OS features like GRES, NSR, and NSB, ensures complete control plane delivery during unexpected failures.

The EX4300 offers high availability features comparable to modular chassis-based switches. Combined with the proven Junos OS and L2/L3 failover capabilities, this provides true carrier-class reliability.

• Dual Power Supplies: EX4300 switches support load-sharing, hot-swappable, and field-replaceable dual internal power supplies for uninterrupted operation. They offer lower power requirements than chassis-based switches with equivalent port density. EX4300 1GbE access switches are available with AC or DC options, while multigigabit models support AC power supplies.
• Hot-Swappable Fans: The EX4300 includes hot-swappable fans to ensure adequate cooling even if one fan fails.
• Nonstop Bridging (NSB) and Nonstop Routing (NSR): EX4300’s NSB and NSR synchronize control plane protocols, states, and tables between the master and standby REs, preventing protocol flaps or convergence issues after a routing engine failover.
• Redundant Trunk Groups (RTG): EX4300 employs redundant trunk groups to provide essential port redundancy and simplify switch configuration, avoiding the complexities of Spanning Tree Protocol (STP) without compromising network resiliency.
• Cross-Member Link Aggregation: This feature supports redundant link aggregation connections between devices within a single Virtual Chassis configuration, enhancing stability and availability.
• Carrier-Class Hardware: The EX4300 integrates the EX-PFE, a custom packet forwarding engine ASIC, utilizing technology found in Juniper’s carrier-class routers for predictable and scalable performance.
• IPv4 and IPv6 Routing: Enhanced licensing supports IPv4 and IPv6 Layer 3 routing (OSPF and BGP) for resilient network operations.

Service-Provider Operating System

The EX4300 runs on Junos OS, the same operating system used across Juniper Networks switches, routers, and security devices. This consistency ensures uniform control plane implementation and operation. Junos OS uses a single source code and a tightly controlled development process, with a single quarterly release train and a highly available, modular architecture that isolates faults to prevent system-wide downtime.

This approach provides core software value, allowing all Junos OS-based products to be updated simultaneously with the same software release. All features undergo rigorous regression testing, and each new release includes all previous functionality, ensuring predictable behavior.

Integrated Networking

The EX4300 provides high availability for environments demanding high performance for integrated data, voice, and video, making it a robust platform for converged enterprise communications.

The EX4300 supports rich Quality of Service (QoS) features to prioritize data, voice, and video traffic. It offers 12 QoS queues per port, enabling granular traffic prioritization. The EX4300 also supports policy options including priority queuing and Weighted Deficit Round-Robin (WDRR) queuing.

The EX4300 offers a future-proof solution for integrating heterogeneous networks onto a single IP infrastructure, providing Class 3 802.3af PoE with up to 15.4W per port to power VoIP phones, security cameras, wireless access points, and other IP-based devices. EX4300 switches also support 802.3at PoE+, delivering up to 30W per port for devices requiring more power, such as 802.11n wireless access points and videophones. The EX4300 multigigabit switches support the emerging IEEE 802.3bt standard for PoE++, providing up to 95W per port for devices needing more power than PoE+.

Security

The EX4300 supports integrated port security and threat detection features, including DHCP snooping, Dynamic ARP Inspection (DAI), IP source guard, and MAC limiting (per port and VLAN), to defend against internal and external snooping, Man-in-the-Middle (MITM), and Denial of Service (DoS) attacks.

MACsec

EX4300 switches support IEEE 802.1AE MACsec, providing Layer 2 data confidentiality, data integrity, and data origin authentication. MACsec enables line-rate hardware-based traffic encryption across all GbE and 10GbE ports, including base and optional uplink modules, for up to 88Gbps. Multigigabit EX4300 models support MACsec AES 256 for traffic encryption on all access and uplink ports.

MACsec provides secure, encrypted communication over the wire, protecting against threats like DoS attacks, MITM attacks, masquerading, passive eavesdropping, and replay attacks. Once deployed on a switch port, MACsec encrypts all traffic on the wire but not within the switch, ensuring secure wired packets while allowing network policies like QoS, deep packet inspection, and sFlow to be applied to each packet.

Hop-by-hop encryption with MACsec ensures communication security while preserving network intelligence. It also secures links over Ethernet-based WAN networks. MACsec is transparent to Layer 3 and above protocols, is not limited to IP traffic, and works for any type of wired or wireless traffic transmitted over an Ethernet link.

LLDP-MED (Link Layer Discovery Protocol-Media Endpoint Discovery) based granular PoE/PoE+ management allows the EX4300 to conserve power by reducing PoE/PoE+ usage to less than 1 watt per powered device, further enhancing PoE utilization across the switch.

The EX4300 supports industry-standard LLDP and LLDP-MED for ease of deployment, enabling switches to automatically discover Ethernet-based devices, determine their power requirements, and assign VLAN parameters.

The EX4300 supports IEEE 802.3az Energy Efficient Ethernet, reducing power consumption on copper physical layer (PHY) ports during periods of low link utilization.

Simplified Management and Operations

Virtual Chassis technology significantly simplifies network management by allowing up to 10 interconnected EX4300 switches to be managed as a single device. Because each Virtual Chassis group uses a single Junos OS image and configuration file, the number of devices to monitor and manage is reduced. When Junos OS is upgraded on the master switch of a Virtual Chassis configuration, the software on all member switches is automatically upgraded simultaneously.

The EX4300 also includes port profiles that enable network administrators to automatically configure ports based on the type of device connected, applying security, QoS, and other parameters. Six pre-configured profiles are available: default, desktop, desktop plus IP phone, wireless access point, routed uplink, and L2 uplink. Users can select from existing profiles or create their own and apply them via CLI, Junos Web Interface, or the management system.

EX4300 switches can be managed by Junos Space® Network Director, a network management solution. Users can visualize, analyze, and control their entire enterprise network—spanning data centers and campuses, physical and virtual, wired and wireless—through a single pane of glass. Network Director integrates real-time intelligence, monitoring trends, and automation for enhanced agility and faster deployment and service activation.

Network Director supports cloud deployments and provides a set of REST APIs that simplify service provisioning in multitenant environments, enabling on-demand and dynamic network services. Network Director APIs integrate with third-party cloud orchestration tools, allowing for automated provisioning of L2, L3, and security services without manual operator intervention.

Additionally, EX4300 switch systems can export performance and fault data to leading third-party management systems such as HP OpenView, IBM Tivoli, and Computer Associates Unicenter for comprehensive network operations visibility.
