Extreme Networks Data Sheet

Designed for High-Performance Network Applications  

Summit X250e switches provide non-blocking architecture with copper and fiber Fast Ethernet ports for demanding edge applications. Combining exceptional QoS and advanced traffic management with resiliency, comprehensive security features and non-blocking performance, Summit X250e switches are designed to be the cornerstone of an advanced intelligent converged network.

Exceptional Policy-based QoS with Advanced Traffic Management for Converged Applications

Summit X250e provides eight hardware queues per port to support granular traffic classification with bandwidth allocation. 1,024 centralized classifiers per 24-port block can use information from Layers 1 through 4 to prioritize and meter incoming packets at line-rate. When metering traffic, the switches can drop out-of-spec traffic or flag it for later action. To expedite upstream traffic handling, a packet’s classification can be carried forward with Layer 2 (802.1p) and Layer 3 (Diffserv) markings.

Summit X250e provides advanced traffic management features that support the high-quality triple play of voice, video and data services.

Efficient Management to Handle Convergence-Driven Network Changes

Universal Port—VoIP

Auto-Provisioning

Summit X250e sets the stage for conver- gence applications by allowing enterprises to add new access devices in a non-disrup- tive plug-and-play fashion. Voice and wireless services can be easily implement- ed without major network upgrades. Summit X250e supports the automated provisioning of VoIP using Link Layer Discovery Protocol (LLDP) and the event-based command scripting capability.

with its support of the IEEE 802.3af standard and full Class 3 power availability on all ports, backed up 100% by the EPS-500 redundant power supply (Summit X250e-24p). Summit X250e-48p can provide up to 370W of PoE power and can be increased up to 740W of PoE power to provide full 15.4W Class 3 devices on all 48 ports by adding an External Power System (EPS-C and EPS-600LS).

Voice-Grade Connections

Granular QoS, low latency and low jitter enable voice-quality connections. Summit X250e supports a range of QoS technologies that can prioritize and predictably handle high-priority traffic policing or rate limiting on ingress, 802.1Q tagging and Diffserv marking, and shaping on egress with eight queues per port. The Extreme Networks tradition of building products with low latency and jitter continues with the Summit X250e series.

Comprehensive Network

Management

As the network becomes a foundation of the enterprise application, network management becomes an important piece of the solution. Summit X250e supports comprehensive network management through Command Line Interface (CLI), SNMP v1, v2c, v3 and an embedded XML-based Web User Interface, ExtremeXOS ScreenPlay™. With a variety

of management options and consistency across other Extreme Networks modular and stackable switches, Summit X250e series switches can provide ease of management for demanding converged applications.

Extreme Networks has developed tools that help save you time and resources in managing your network. EPICenter® management suite provides fault, configuration, accounting, performance and security functions, allowing more effective management of Extreme Networks multi- layer switching equipment in a converged network.

Advanced Routing Capabilities for the Edge

Summit X250e supports advanced protocols for an efficient and productive network. Summit X250e switches provide static and RIP routing for simple IPv4 and IPv6 Layer 3 deployment. An optional ExtremeXOS Advanced Edge license extends the feature set to include other important edge functions such as:

•Edge OSPF for much greater extensi- bility than RIP can provide

•Edge PIM sparse modes for routing of multicast streams

•Policy-based routing

•sFlow® hardware sampling

It allows dynamic configuration of voice VLANs and QoS. This auto-configuration capability allows you to configure VoIP phone settings such as voice VLAN settings, call server IP address configuration, etc. (see Figure 3). This level of simplicity in managing network changes can reduce operating expenses.

Power over Ethernet

Deployments of IP Telephony depend on reliable, consistent power from the Ethernet jack. Summit X250e-24p and Summit X250e-48p are the basis for a reliable LAN telephony infrastructure with fully redundant resiliency to match the failover requirements for latency-sen- sitive services like VoIP phones. With Summit X250e-24p or 48p, deployment of powered LAN devices is quick and easy
