Features and Benefits
High Availability Features
• Redundant Trunk Group (RTG): To avoid the complexities of
the Spanning Tree Protocol (STP) without sacrificing network
resiliency, the EX2200 employs a redundant trunk group to provide
the necessary port redundancy and simplify switch configuration.

Junos Operating System
The EX2200 runs the same Junos OS used by other Juniper
Networks EX Series Ethernet Switches, as well as all of Juniper’s
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.

Converged Environments
The EX2200 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 EX2200 delivers a future proofed solution
for converging disparate networks onto a single IP infrastructure.

The EX2200 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.

To ease deployment, the EX2200 supports the industry-standard
Link Layer Discovery Protocol (LLDP) and LLDP-Media 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 EX2200
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 EX2200 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 EX2200 also support a wide range of policy
options, including strict priority, low-latency, weighted random
early detection (WRED), and shaped deficit weighted round-robin
(SDWRR) queuing.

Security
The EX2200 fully integrates with Juniper Networks Unified Access
Control, which consolidates all aspects of a user’s identity, device,
and location. This enables administrators to enforce access
control and security down to the individual port or user levels.
Control, which consolidates all aspects of a user’s identity, device,
and location. This enables administrators to enforce access
control and security down to the individual port or user levels.
Working as an enforcement point within UAC, the EX2200
provides both standards-based 802.1X port-level access
control for multiple devices per port, 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’s
device to a specific VLAN based on authorization policy. 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.
