Simplified Management and Operations
when employing Virtual Chassis technology, the EX4300 
dramatically simplifies network management. Up to 10 
interconnected EX4300 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 EX4300 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 to 
the port. Six preconfigured profiles are available, including 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), Junos web interface, or management system. 
when managing a group of EX4300 switches, Juniper Networks 
Junos Space Network Director provides system-level management 
across all Juniper switches in the network, from a single console.
Finally, the EX4300 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.
