Working as an enforcement point within the UAC, 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 to
defend against internal and external spoofing, man-in-the-middle
and denial-of-service (DoS) attacks.

Simplified Management and Operations
When employing Virtual Chassis technology, the EX4200
dramatically simplifies network management. Up to 10
interconnected EX4200 switches can be managed as a single
device. Each Virtual Chassis group utilizes a single Junos OS image
file and a single configuration file, reducing the overall number
of units to monitor and manage. When Junos OS is upgraded on
the master switch in a Virtual Chassis configuration, the software
is automatically upgraded on all other member switches at the
same time.

The EX4200 also includes port profiles that allow network
administrators to automatically configure ports with security, QoS
and other parameters based on the type of device connected

default, desktop, desktop plus IP phone, wireless access point,
routed uplink and Layer 2 uplink. Users can select from the existing
profiles or create their own and apply them through the command
line interface (CLI), J-Web interface or management system.

Four system management options are available for the EX4200.
The standard Junos OS CLI management interface offers the same
granular capabilities and scripting parameters found in any device
powered by Junos OS. The EX4200 also includes the integrated
J-Web management tool, an embedded device manager that
allows users to configure, monitor, troubleshoot and perform
system maintenance on individual switches via a browser-based
graphical interface.

When managing a group of EX4200 switches, the Juniper
Networks Network and Security Manager (NSM) provides system-
level management across all Juniper switches in the network, from
a single console.

Finally, the EX4200 switch system, performance and fault data can
be exported to leading third-party management systems such as HP
OpenView, IBM Tivoli and Computer Associates Unicenter software,
to provide a complete, consolidated view of network operations.
