In keeping with the increasing complexity of Allied Telesis' ever-improving and feature-rich software, AlliedWare Plus employs a new modular approach to software creation and distribution. It represents a quantum shift in the software development methodology for Allied Telesis switches and routers - providing you with even more features and greater robustness from the operating system. The AlliedWare Plus operating system combines superior networking functionality and strong management capabilities with the exceptional performance that today's networks demand. A standards-based implementation, it also assures full interoperability with other major network equipment, along with improved usability and therefore a superior customer experience. High-Performance and High-Availability Virtual Chassis Stacking Virtual Chassis Stacking makes networking simple. It allows you to connect between 2 and 81 switches together via high-bandwidth 15Gbps stacking links.This aggregates the switches, which then appear as a single switch, or 'Virtual Chassis'. The Virtual Chassis can be configured and managed via a single serial console or IP address, which provides greater ease of management in comparison to an arrangement of individually managed switches, and often eliminates the need to configure protocols like VRRP and Spanning Tree. Virtual Chassis Stacking provides a high availability system where network resources can be spread out across a number of stacked switches, thus reducing the impact should any one of the stacked switches fail. Ports on different switches across the stack can be aggregated to provide excellent link redundancy. Hot-swappable XEM modules The AlliedWare Plus operating system supports hot-swappable XEM modules, dramatically reducing system downtime.You can remove and add XEM modules, or swap a XEM for another of the same sort - all without having to reboot or reconfigure your network. Modularity + Monitoring = Robust Flexibility AlliedWare Plus has a modular architecture, providing superior reliability. It uses separate software processes, or modules, to handle different functions - for example management, routing protocols, and control functions. Each of these modules can only access its own allocated memory, which prevents processes from corrupting each other and causing system crashes. Although independent of each other, modules communicate via well-defined interfaces. To achieve even greater reliability, independent monitoring software has been utilized alongside the modular architecture.This provides passive monitoring and periodic health checks for all important processes, and sends messages to inform system administrators of issues and resolutions. Industry Standard Command Line Interface (CLI) The AlliedWare Plus operating system incorporates an industry standard CLI, facilitating intuitive manageability. Each command is associated with a specific function, or a common function performing a specific task.You can automate some of your configuration tasks, as many of these commands may also be used in scripts.Triggers can also be utilized, providing a powerful mechanism for automatic and timed management by automating the execution of commands in response to specific events.

Support for more than 2 units will be available in a future release. Allied Telesis AlliedWare PlusTM | Operating System Continued from previous page. With three distinct modes, the CLI is very secure. User exec mode allows users to view settings and troubleshoot problems but does not allow any changes to be made to the system. Privileged execmode allows users to change system settings and restart the device. Configuration changes are only permitted in global configuration mode, which reduces the risk of making accidental configuration changes.
