Virtual Chassis Technology

The EX4600 supports Juniper Networks’ unique Virtual Chassis technology, which enables up to 10 interconnected switches to operate as a single, logical device with a single IP address. Virtual Chassis technology enables enterprises to separate physical topology from logical groupings of endpoints, ensuring efficient resource utilization. The EX4600 can participate in the same Virtual Chassis configuration with the Juniper Networks EX4300 Ethernet Switch, delivering highly flexible and scalable configuration options for enterprise distribution deployments.

EX4600 switches in a Virtual Chassis configuration can be connected using up to 16 of the 10GbE or 40GbE ports in link aggregation groups (LAGs) across 10GbE/40GbE ports, providing an aggregate backplane capacity of up to 1.04 Tbps.

In the data center, EX4600 Virtual Chassis deployments can extend across multiple top-of-rack or end-of-row switches, providing tremendous configuration flexibility for 10GbE server connectivity by only requiring redundant links between Virtual Chassis groups rather than each physical switch to ensure high availability. In addition, mixed Virtual Chassis configurations featuring EX4300 and EX4600 switches provide an ideal solution for data centers with a mix of 1GbE and 10GbE servers, or for environments transitioning from 1GbE to 10GbE server connectivity.

Enterprise Advantages

The EX4600 delivers a highly available, simple, and scalable 10GbE solution in a compact and power-efficient platform, making it a perfect fit for enterprise networks.


Virtual Chassis technology on the EX4600 dramatically simplifies the enterprise distribution layer, eliminating the need for Spanning Tree Protocol (STP), Virtual Router Redundancy Protocol (VRRP), complex routing, or VLAN configurations. In addition, when deployed in a Virtual Chassis configuration, the EX4600 reduces the number of devices to manage and can even eliminate network switching layers. A single Virtual Chassis configuration can span multiple nodes, reducing the need for larger, more expensive nodes on superior tiers. Juniper Networks Junos® operating system, which is common across the entire EX Series Ethernet Switches product family, accelerates the learning curve by enabling the entire architecture to be managed with a common set of instructions from a single pane of glass.


A single EX4600 can support up to 72 10GbE ports (using 10GbE breakout cables on 40GbE fixed ports) at line rate, providing a highly scalable solution for the most demanding environments. In addition, Virtual Chassis technology makes it easy to scale the network while reducing management complexity. By adding switches to a Virtual Chassis configuration, it is possible to grow the number of switch ports without increasing the number of devices to manage. As switches are added to a Virtual Chassis configuration, backplane bandwidth demands can be scaled to maintain adequate oversubscription ratios. Using just two 40GbE interfaces, Virtual Chassis bandwidth can start at 160 Gbps and grow to 960 Gbps, forming a LAG on all 12 40GbE interfaces.

Highly Available

When EX4600 switches are deployed in a Virtual Chassis configuration, Junos OS initiates a process to assign a primary (active) and backup (hot standby) switch to manage the configuration. If the primary switch fails, an integrated L2 and L3 graceful Routing Engine switchover (GRES) feature automatically switches to the backup to maintain continuous and uninterrupted system operations. The EX4600 switch also includes a number of other high availability features, including redundant power and cooling, graceful protocol restart, equal-cost multipath (ECMP), LAG links distributed across multiple slots, and quality of service (QoS) to prioritize time-sensitive data, nonstop bridging (NSB), nonstop active routing (NSR), and unified in-service software upgrades (unified ISSU). Unified ISSU is currently supported only in standalone configurations; support in Virtual Chassis configurations will be enabled in a future release.

Adaptable and Modular

As business grows, the network needs to evolve. With its compact 1 U form factor and complete switch features, the EX4600 can be easily redeployed in different environments and physical layouts. EX4600 switch capacity can be expanded without increasing the number of managed devices by simply adding more switches to a Virtual Chassis configuration.

Enterprise Deployments

The EX4600 offers an economical, power-efficient, and compact solution for aggregating 10GbE expansions from access devices in building and enterprise deployments. The switch’s dual-speed interfaces also support environments transitioning from 1GbE to 10GbE. The EX4600 can be deployed in the distribution layer with multichassis link aggregation (MC-LAG) (see Figure 1) to deliver higher resiliency with a distributed control plane, NSB, NSR, and unified ISSU. Multichassis LAG enables two EX4600 switches to act as separate devices with their own control planes, while eliminating STP by allowing link aggregation on the connected devices. In addition, unified ISSU allows each of the EX4600 switches to be upgraded individually without service interruption.

If manageability is a concern, the EX4600 can be deployed in a Virtual Chassis configuration to create a single management and control plane, NSB, NSR, and nonstop software upgrade (NSSU) (see Figure 2). If the total number of access switches in a building is eight or fewer, the EX4600 can form a mixed Virtual Chassis configuration with EX4300 switches in the wiring closet, enabling all switches in the building to be managed as a single device (see Figure 3).


Figure 5: Mixed Virtual Chassis configuration with EX4600 and EX4300 switches.

The EX4600 easily meets enterprise core switch requirements, delivering wire-speed performance on every port, full device redundancy, support for L3 dynamic routing protocols such as RIP and OSPF, L2 and L3 MPLS VPNs, and a comprehensive security and QoS feature set.

Campus Distribution Supporting IP Clos

A pair of interconnected EX4600 switches can provide EVPN L2 VXLAN gateway support, eliminating the need for STP across the campus network by providing a multihoming capability from the access layer to the distribution layer. Meanwhile, an IP fabric with a centrally routed bridging overlay supports distribution to the core. In centrally routed bridging mode, core devices act as the EVPN L2/L3 VXLAN gateway. The IP fabric can also be extended to connect multiple enterprise locations, while VXLAN allows stretching L2 across buildings.

The campus fabric IP Clos architecture pushes VXLAN Layer 2/3 gateway functionality to the access layer, and the EX4600 switch acts as an IP fabric distribution switch.

Junos Operating System

The EX4600 runs the same Juniper Networks Junos operating system that is used by other EX Series Ethernet Switches, as well as all Juniper routers and Juniper Networks SRX Series Services Gateways. By utilizing a common operating system, Juniper delivers a consistent implementation and operation of control plane features across all products. To maintain that consistency, Junos OS adheres to a highly disciplined development process that uses a single source code, follows a single quarterly release train, and 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 will be maintained and operate in the same way.

Features and Benefits

EX4600 Ethernet switches include the following key features and benefits:

  • Wired service level expectations: The Wired Assurance feature provides operational visibility into the wired experience with service-level expectations (SLEs) for EX Series Switches. Pre- and post-connection performance metrics help you monitor successful connects and switch health throughout the system, using Mist AI to measure and manage networks and simplify troubleshooting.
  • High performance: Each EX4600 supports up to 1.44 Tbps of bandwidth or 1.07 Bpps at the minimum Ethernet frame size, with 24 line-rate 10GbE fixed ports, 4 40GbE fixed ports, and 2 expansion slots that can each support either a 4x40GbE module or an 8x10GbE module.
  • Unified in-service software upgrade (unified ISSU): With its Intel core processor, the EX4600 switch allows Junos OS to run within a virtual machine (VM) on Linux. Junos OS runs in two separate VMs in active and standby pairs; during software upgrade cycles, the switches seamlessly move to the newer software version while maintaining intact data plane traffic. This true topology-independent ISSU (TISSU), an industry-first software upgrade feature for a fixed-configuration top-of-rack switch, is supported across all L2 and L3 protocols and doesn’t need the support of any other switches to perform an image upgrade.
  • High availability: EX4600 switches offer dual internal load-sharing AC power supplies and redundant variable-speed fans as standard features, protecting the switch from a single power supply or fan failure. DC power options are also available.
  • Automation: The EX4600 switches support a number of features for network automation and plug-and-play operations. Features include zero touch provisioning (ZTP), operations and event scripts, automatic rollback, and Python scripting. The switch also offers support for integration with VMware NSX Layer 2 Gateway Services, Puppet, and OpenStack.
  • Energy efficient: Consuming less than five watts per 10GbE interface, the EX4600 offers a low power solution for 10GbE top-of-rack, end-of-row, and distribution deployments. The EX4600 switches also improve cooling efficiency with redundant variable-speed fans that automatically adjust their speed based on existing conditions to reduce power consumption.
  • Small footprint: The EX4600 supports up to 72 wire-speed 10GbE ports in a single 1 U platform.
  • Juniper Extension Toolkit: An evolution of the Junos software developer's kit (SDK), Juniper Extension Toolkit (JET) provides a modern, programmatic interface for third-party application developers.
  • Flexible forwarding table: The EX4600’s flexible forwarding table allows the hardware table to be carved into configurable partitions of L2 media access control (MAC), L3 host, and longest prefix match (LPM) tables. In a pure Layer 2 environment, the EX4600 supports up to 288,000 MAC addresses. In Layer 3 mode, the table can support up to 128,000 host entries; in LPM mode, it can support up to 128,000 prefixes. Junos OS provides configurable options through a CLI so that each EX4600 can be optimized for different deployment scenarios.
  • Intelligent buffer management: EX4600 switches have a total of 12 MB shared buffers. While 25 percent of the total buffer space is dedicated, the rest is shared among all ports and is user configurable. The intelligent buffer mechanism in the EX4600 effectively absorbs traffic bursts while providing deterministic performance, significantly increasing performance over static allocation.
  • Insight technology for analytics: The EX4600 provides dynamic buffer utilization monitoring and reporting with an interval of 10 milliseconds to provide microburst and latency insight. It calculates both queue depth and latency, and logs messages when configured thresholds are crossed. Interface traffic statistics can be monitored at two-second granularity. The data can be viewed via CLI, system log, or streamed to external servers for more analysis. Supported reporting formats include Java Script Object Notification (JSON), comma-separated values (CSV), and tab-separated values (TSV). These files can be consumed by orchestration systems, SDN controllers, or network management applications (such as Juniper Networks Junos Space Network Director) to make better network design decisions and identify network hotspots.
  • MPLS: EX4600 switches support a broad set of MPLS features, including L2VPN, L3VPN, IPv6 provider edge router (6PE), RSVP traffic engineering, and LDP to allow standards-based network segmentation and virtualization. The EX4600 can be deployed as a low-latency MPLS label-switching router (LSR) or MPLS provider edge (PE) router in smaller scale environments. The EX4600 is the industry’s only compact, low-latency, high-density, low-power switch to offer an MPLS feature set.
  • MACsec: The EX4600 is capable of MACsec features on all 10GbE ports to support 400 Gbps of near line-rate hardware-based traffic encryption on all fiber ports, including the base unit and optional 10GbE expansion modules. MACsec in software will be enabled in a future release.
