Switches deployed in close proximity, such as wiring closets or top-of-rack data center applications, can be securely connected using a Virtual Chassis cable and cable lock supplied by Juniper Networks. Different models can be mixed in a Virtual Chassis configuration to provide a variety of port and density options. In a Virtual Chassis configuration, all switches are monitored and managed as a single device, enabling enterprises to separate physical topology from logical groupings of endpoints and allowing more efficient resource utilization.
Highly resilient topologies can also be created using the GbE or 10 GbE uplink ports to extend the Virtual Chassis configuration across long distances spanning multiple wiring closets, floors or even buildings. Using Virtual Chassis technology, up to 10 EX switches can be interconnected to create a single logical device spanning multiple wiring closets, floors or even buildings.
The EX line of Ethernet switches deliver the same HA functionality and support many of the same failover capabilities as other Juniper chassis-based systems. Each EX switch is capable of functioning as a Route Engine. When two or more EX switches are interconnected, they share a single control plane among all Virtual Chassis member switches.
When more than two switches are interconnected in a Virtual Chassis configuration, the remaining switch elements act as line cards and are available to assume the backup RE position should the designated master fail. By utilizing a consistent operating system and a single configuration file, all switches in a Virtual Chassis configuration are treated as a single device, simplifying overall system maintenance and management.
Individually, the EX offers a number of HA features that are typically associated with modular chassis-based switches. 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 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 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.
The EX line 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 In addition, the EX 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. Junos OS utilizes a single source code, adheres to a consistent and predictable release train, and employs a single modular architecture. 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. When employing Virtual Chassis technology, the EX dramatically simplifies network management. Up to 10 interconnected EX switches can be managed as a single device. Each Virtual Chassis group utilizes a single JUNOS Software image file and a single configuration file, reducing the overall number of units to monitor and manage.
When JUNOS Software 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 EX 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 , J-Web interface or management system. Four system management options are available for the EX The EX 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.
Finally, the EX 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.
