Ideal for enterprises moving to a converged network now or in the future, the Ethernet Routing Switch 2500 offers the resiliency, performance and simplified operational features you need, while helping keep on-going total cost of ownership low. Convergence-ready for Unified Communications and more For businesses looking to consolidate all forms of communication – data, voice and video – on a single infrastructure, the Avaya ERS 2500 delivers functionality that simplifies convergence of these technologies.
Through support for standards-based Power-over-Ethernet (IEEE 802.3af PoE), power is delivered to IP phones, wireless access points, networked CCTV cameras and other devices. This eliminates the need for separate power supplies for each unit, enabling reduced cabling and management costs for adds, moves or changes.
The Avaya ERS 2500 further optimizes power consumption by allowing each port to be configured to a power priority level of low, high or critical, limiting the amount of power delivered to non-business-critical devices. This unique design delivers a flexible convergence-ready solution that can help keep costs low for customers.
Simplifies IP phone deployments With Avaya’s auto-discovery and configuration capability (ADAC), the Avaya ERS 2500 automatically configures the switch to apply correct Quality-of-Service (QoS) and VLAN settings, making mass IP phone deployments quick and easy. Standards-based 802.1AB auto-discovery can be used for non-Avaya devices.

Delivering unsurpassed control for networks requiring sophisticated capabilities, advanced QoS functions of the Avaya ERS 2500 enable management of egress queue shaping, mutation of DiffServ Code Point values on egress, definition of filter sets using both Layer 2 and Layer 3 (IP) criteria, and full optimization of the schema for queue and buffer management. With these new QoS capabilities, the Avaya ERS 2500 Series delivers a superlative quality management solution.
Automatic QoS In addition to supporting certain Avaya Unified Communications and voice solutions through recognition of Differentiated Service Code Point (DSCP) values unique to these applications, Automatic QoS optimizes management of egress queues. Intelligent stacking solution delivering scalability, flexibility, resilience and performance A stack of up to eight Avaya ERS 2500 units can be created (via a stacking license or stack-enabled units), enabling the Ethernet Routing Switch 2500 series to deliver up to 32 Gbps stacking throughput by scaling up to 384 10/100 ports and 16 10/100/1000/ SFP combo ports. Industry-leading, pay-as-you-grow scalable capacity
Using our stackable solutions to combine non-blocking internal switching fabrics with a high-speed stacking architecture, Avaya offers a truly high performance solution designed to scale proportionally as new switches are added. Shortest-path traffic forwarding capability, providing the most optimal path for each data flow, is at the heart of our stackable chassis architecture. Our solution does away with unwieldy logical ring or token technology found in competing offers. Instead, Avaya uses a physical/logical ring topology that allows traffic to flow upstream and downstream simultaneously from every switch in the stack, optimizing performance, resiliency, and resource utilization.In-service maintenance and restoration Virtual hot swap, a critical serviceability and operability capability, helps ensure that failure in any unit is quickly and easily rectified. Pioneered in modular switches, virtual hot swap is available in Avaya stackable chassis solutions where, without complex engineering, it enables immediate like-for-like unit replacement with no impact on other functionality and traffic, empowering operators to deploy our solutions just as they would a chassis. If a failure occurs, neighboring switches automatically wrap their fabric connections to help ensure that other switches in the stack are not impacted. The failed unit is simply disconnected from the fabric and, without pre-staging of software or configuration, a like unit is inserted, cabled, and powered-up. The Automatic Unit Replacement (AUR) process self-manages downloads to the new switch then brings it online without the need for an engineer to configure or manage the process.
Further complementing the Avaya ERS 2500 stacking architecture, Avaya supports standards-based 802.3ad Link Aggregation as well as its own Multi-Link Trunking technology that allows grouping of ports to form high-speed trunks/aggregations. These bundles or groups of ports can be distributed across different units in the same stack, delivering higher levels of resilience in case of link or switch failure to help ensure that traffic gets to its destination.
Stack health-check monitoring, a real-time, at-a-glance view of stack operational status and health, further enhances operational and management simplicity.
Automatic software/configuration control and centralized management
With chassis solutions, implementation and management consists of adding a new module, configuring the module, and connecting devices. With Avaya stackables, the process is just as simple: cable in the new member then extend appropriate configuration. Through the AUR feature, the diagnostic image and agent image software is automatically checked and updated if necessary to the new member. If a replacement unit is being inserted, the AUR self management function will also download and restore the configuration file in addition to the diagnostic and agent images. All units in a switch stack operate and are managed as a single network entity.
Securing access at the edge The ERS 2500 offers a wide range of flexible security options to help ensure that only authorized personnel gain access to the LAN. Through either an IEEE 802.1X-based EAP client or device MAC Address, network managers control authentication for access to specific resources.
When advanced, standards-based, policy-based and centralized user/device authentication is required, the Avaya ERS 2500 can be used in conjunction with the innovative
Avaya Identity Engines portfolio solution to assign network access rights and permissions based on user role, where user connects (local or remote), and whether or not the connection is wired or wireless. In this way, every connected device is known and adheres to established security policies. As the number of employee-owned devices requesting access to the corporate network increases, Identity Engines helps network operators retain control. Running device health checks and verifying credentials of users and devices requesting access, Identity Engines helps ensure that network access permission levels are enforced and adhered to.
In addition, the Avaya ERS 2500 offers advanced security services that enable the Avaya ERS 2500 to actively protect against malicious network attacks. These services include protection from snooping of DHCP services, verification and filtering of ARP traffic via in-hardware processing (Dynamic ARP inspection), restriction of IP traffic to registered end devices (IP Source Guard), and control of the flow of Spanning Tree BPDUs within the network (BPDU Filtering).
Avaya ERS 2500 also supports advanced packet classification and deep packet filtering of up to 128 bytes, helping block unwanted network traffic while forwarding mission-critical traffic efficiently. Secure and simplified network management
Supported on all Avaya ERS 2500 models, Avaya Ethernet switch software simplifies network operations and management because a single image operates on any mixture of models in a stack. Eliminating worry about different software versions and capabilities on different products, the software image is loaded on the base unit of the stack which then loads the image to other switches. As switches are added to an existing stack, Avaya ERS 2500 software helps ensure that new switch diagnostics and software are added to software already running on the stack.
The Avaya ERS 2500 supports secure management via IPv4 or IPv6 through access control lists, and administrative authentication via RADIUS or TACACS+ when connecting to the switch or stack.
Creating a flexible operational environment, the Avaya ERS 2500 Series can be managed by a variety of management tools including standardized Command Line Interface (CLI), Web-based Enterprise Device Manager (EDM), SNMP-based management (SNMPv1, v2 & v3), HTTPS (Secure Web), and the evolving Unified Communication Management (UCM) framework for comprehensive, centralized, multi-facetted network management. UCM is based on Common Services (authentication and access control, audit, etc.) and the following integrated plug-in AJAX-based applets that deliver seamless task-specific capabilities with a consistent look and feel:
Configuration & Orchestration Management
Visualization, Performance, & Fault Management
Enterprise Policy Manager
IP Flow Manager
Network Resource Manager
Provision Wizards and other labor-saving tools provide faster service activation and a more consistent approach to configuration. And, because templates are pre-populated with best-practice recommendations or mandatory values, they can reduce human error. The entire framework is context-based, enabling a faster, more accurate and intelligent approach to delivering both device-centric and network-wide management services.
