Product Overview:

The Juniper Networks EX2300 Ethernet Switch offers an economical, entry-level, standalone solution for accesslayer deployments in branch and remote offices, as well as enterprise campus networks. Both 1 Gbps and 2.5 Gbps access port options are available to provide higherspeed options, especially when connecting to 802.11ac Wave 2 access points.

To simplify network operations, the EX2300 can act as a satellite device to support a Juniper Networks Junos Fusion Enterprise deployment, which can combine several wiring closets into one logical management platform. For smaller networks, up to four EX2300 switches can be interconnected in a Virtual Chassis configuration, allowing them to be managed as a single switch.

Product Description

The Juniper Networks® EX2300 line of Ethernet switches offers a compact, highperformance solution for supporting today's converged network access deployments.

Each EX2300 switch includes an ASIC-based Packet Forwarding Engine (PFE) with an integrated CPU to consistently deliver wire-rate forwarding, even with all control plane features enabled. Based on existing, field-proven Juniper Networks technology, the PFE brings the same level of carrier-class performance and reliability to the EX2300 switches that Juniper Networks routers bring to the world's largest service provider networks.

Select EX2300 models also support the 802.3af Class 3 Power over Ethernet (PoE) and 802.3at PoE+ standards for supporting networked devices such as telephones, video cameras, IEEE 802.11ac WLAN access points, and videophones in converged networks. The PoE-enabled EX2300 switches include a maximum system budget of 740 watts to deliver up to 30 watts to select ports.

Multiple EX2300 models are available, including versions offering multigigabit (up to 2.5 Gbps) PoE+ access ports that can accommodate higher-speed IEEE 802.11ac Wave 2 access points, enabling the switches to support more wireless users.

The EX2300 fixed-configuration Ethernet switches provide exceptional value to enterprise customers by supporting the following key technologies:

  • Juniper Networks Junos® Fusion Enterprise allows up to 128 EX2300 switches to be configured as satellite devices that connect to EX9200 core aggregation devices.
  • Virtual Chassis technology enables up to four interconnected EX2300 switches to form a single logical device.
  • Flexible 4x1GbE SFP/10GbE SFP+ uplinks provide high-speed connectivity to aggregation layer switches or other upstream devices.
  • Up to 48 10/100/1000BASE-T ports are available with or without PoE/PoE+.
  • Energy Efficient Ethernet (EEE) support is provided on 1GbE ports.
  • Complete Layer 2 and basic Layer 3 switching capabilities are available.
  • Simplified management uses Juniper Networks Junos Space Network Director and J-Web GUI.

Additional features include:

  • PoE-enabled EX2300 switches can simultaneously deliver up to 15.4 watts of standards-based 802.3af Class 3 PoE to a maximum of 48 ports or 30 watts of standards-based 802.3at PoE+ to a maximum of 24 ports, based on a total system budget of 740 watts.
  • Uplink ports can be configured as Virtual Chassis interfaces and connected via standard 10GbE optics interfaces (optional license required).
  • Fixed power supply and uplink ports ensure operational simplicity.
  • Low power consumption, low acoustic fans, and a small 10-inch deep footprint enable flexible, environmentally friendly deployment.
  • Support for L2 protocols as well as L3 protocols like RIP and static routing are included in the base license.
  • An optional enhanced license is available for supporting additional L3 protocols such as OSPF, Internet Group Management Protocol (IGMP v1/v2/v3), Protocol Independent Multicast (PIM), Bidirectional Forwarding Detection (BFD), MLD v1, MLD v2, MLD snooping, and Virtual Router Redundancy Protocol (VRRP).
  • Support is available for IPv6 management, including neighbor discovery, telnet, SSH, DNS, system log, and NTP.
  • A single release train for Juniper Networks Junos operating system is supported to ensure a consistent control plane feature implementation.
  • Modular Junos OS prevents a switch reboot if a single protocol feature fails.
  • Built-in Web interface (Juniper Networks J-Web Software) is provided.
  • RJ-45 serial console port is available.
  • USB mini console port is included on 1GbE access switch models.
  • Out-of-band Ethernet management port is provided.
  • Reduction of Hazardous Waste (RoHS) is certified.

Features and Benefits:

High Availability Features

To avoid the complexities of the Spanning Tree Protocol (STP) without sacrificing network resiliency, the EX2300 employs a redundant trunk group (RTG) to provide the necessary port redundancy and simplify switch configuration. It also supports cross-member link aggregation, which allows redundant link aggregation connections between devices in a single Virtual Chassis configuration, providing an additional level of reliability and availability.

Junos Operating System

The EX2300 switches run the same Junos OS that is used by other Juniper Networks EX Series Ethernet Switches, QFX Series Switches, Juniper Routers, Juniper SRX Firewalls, and the Juniper NFX Series Network Services Platform. By utilizing a common operating system, Juniper delivers a consistent implementation and operation of control plane features across all products. To maintain that consistency, the Junos OS adheres to a highly disciplined development process that uses a single source code, and it employs a highly available modular architecture that prevents isolated failures from bringing down an entire system.

These attributes are fundamental to the core value of the software, enabling all Junos OS-powered products to be updated simultaneously with the same software release. All features are fully regression-tested, making each new release a true superset of the previous version. Customers can deploy the software with complete confidence that all existing capabilities are maintained and operate in the same way.

Converged Environments

The EX2300 provides the highest levels of flexibility and features in its class for the most demanding converged data, voice, and video environments, delivering a reliable platform for unifying enterprise communications.

By providing a full 15.4 watts of Class 3 PoE to VoIP telephones, closed-circuit security cameras, wireless access points, and other IP-enabled devices, the EX2300 delivers a future-proofed solution for converging disparate networks onto a single IP infrastructure. The EX2300 PoE switches also support 802.3at standards-based PoE+, delivering 30 watts for powering networked devices such as IEEE 802.11ac wireless access points, and videophones that might require more power than available with IEEE 802.3af.

To ease deployment, the EX2300 supports the industrystandard Link Layer Discovery Protocol (LLDP) and LLDPMedia Endpoint Discovery (LLDP-MED) protocol, enabling the switches to automatically discover Ethernet-enabled devices, determine their power requirements, and assign virtual LAN (VLAN) membership. LLDP-MED-based granular PoE management allows the EX2300 to negotiate PoE usage down to a fraction of a watt on powered devices, enabling more efficient PoE utilization across the switch.

In addition, the EX2300 supports rich quality-of-service (QoS) functionality for prioritizing data, voice, and video traffic. The switches support eight class-of-service (CoS) queues on every port, enabling them to maintain multilevel, end-to-end traffic prioritizations. The EX2300 also supports a wide range of policy options, including strict priority, low latency, weighted random early detection (WRED), and shaped-deficit weighted roundrobin (SDWRR) queuing.


Working as an enforcement point in Access Policy Infrastructure, the EX2300 provides both standards-based 802.1X portlevel access control for multiple devices per port, as well as Layer 2-4 policy enforcement based on user identity, location, device, or a combination of these. A user's identity, device type, machine posture check, and location can be used to determine whether access should be granted and for how long. If access is granted, the switch provides access to the network based on authorization attributes sent by the authentication server. The switch can also apply security policies, QoS policies, or both, or it can mirror user traffic to a central location for logging, monitoring, or threat detection by intrusion prevention systems.

The EX2300 also provides a full complement of integrated port security and threat detection features, including Dynamic Host Configuration Protocol (DHCP) snooping, dynamic ARP inspection (DAI), and media access control (MAC) limiting to defend against internal and external spoofing, and man-in-themiddle and denial of service (DoS) attacks.
