EX4200 Ethernet Switch

• Non-Stop Software Upgrade (NSSU): With NSSU, all

members of a Virtual Chassis system can be upgraded

with a single command. Mission-critical traffic can be

configured as a link aggregate across multiple Virtual

Chassis switch members, ensuring minimal disruption

during the upgrade process.

• IPv4 and IPv6 routing support: IPv4 and IPv6 Layer 3

routing (OSPF and PIM) is available in the base license,

enabling highly resilient networks.

Carrier-Class Operating System

The EX4200 runs on Junos OS, the same operating system

software used by Juniper Networks routers to power the world’s

largest and most complex networks.

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

utilizes a single source code, follows a single quarterly release

train, and employs a highly available modular architecture that

prevents isolated failures from bringing an entire system down.

These attributes are fundamental to the core value of the

software, enabling all products powered by Junos OS 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.

Converged Networks

The EX4200 line of Ethernet switches provide the highest levels

of availability for the most demanding converged data, voice and

video environments, delivering the most reliable platform for

unifying enterprise communications.

By providing Class 3 PoE with 15.4 watts on some or all ports

to power voice over IP (VoIP) telephones, closed-circuit security

cameras, wireless access points, and other IP-enabled devices,

the EX4200 delivers a future-proofed solution for converging

disparate networks onto a single IP infrastructure. Furthermore,

any PoE port can provide up to 18.6 watts to power wireless

access points and other PoE powered devices requiring more

than Class 3, 15.4 watts of PoE. EX4200 PoE+ switches also

support 802.3at standards-based PoE+ for powering networked

devices like multiple radio IEEE 802.11n wireless access points,

and video phones that may require more power than available

with IEEE 802.3af.

LLDP-MED-based granular PoE management allows the

EX4200 to negotiate PoE usage down to a fraction of a watt on

powered devices, enabling more efficient PoE utilization across

the switch.

To ease deployment, the EX4200 supports the industry-

standard Link Layer Discovery Protocol (LLDP) and LLDP-Media

Endpoint Discovery (LLDP-MED), which enable the switches to

automatically discover Ethernet-enabled devices, determine their

power requirements and assign virtual LAN (VLAN) parameters.

In addition, the EX4200 supports rich quality of service (QoS)

functionality for prioritizing data, voice and video traffic. The

switches support eight QoS queues on every port, enabling

them to maintain multi-level, end-to-end traffic prioritizations.

The EX4200 also supports a wide range of policy options,

including priority and shaped deficit weighted round-robin

(SDWRR) queuing.

Security

The EX4200 line of Ethernet switches consolidate all aspects of

a user’s identity, device, and location, enabling administrators to

enforce access control and security down to the individual port

or user levels.

Policy orchestration enables the EX4200 to construct dynamic

ACLs on a port-by-port basis by associating role/resource

access policies with authorization table entries. This allows the

switch to dynamically create thousands of ACLs or role-based

access policies in a scaled environment.

Additionally, a captive portal redirection feature redirects

URLs from the EX4200 to the Infranet Controller (IC) for user

authentication and authorization, making the IC a “single source

of truth” for user and device authentication and for enforcing

role-based security policies.

The EX4200 provides both standards-based 802.1X port-

level access control as well as Layer 2–4 policy enforcement

based on user identity, location and/or device. 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 assigns the user

to a specific VLAN based on authorization levels. The switch

can also apply QoS policies or mirror user traffic to a central

location for logging, monitoring or threat detection by intrusion

prevention systems.

The EX4200 also provides a full complement of port security

features including DHCP (Dynamic Host Configuration Protocol)

snooping, DAI (dynamic ARP inspection) and MAC limiting (per

port and per VLAN) to defend against internal and external

spoofing, man-in-the-middle and denial-of-service (DoS) attacks.
