Extreme Networks Data Sheet Summit®48si The extensive capabilities of the Summit48si fit a large span of application spaces, both within an enterprise and a metro network. Quality of Service and Application Flexibility • Bidirectional rate shaping • DiffServ and 802.1p • Virtual MANs (vMANs) • Policy-Based Quality of Service (QoS) with 8 queues per port High Network Availability • Redundant hot-swappable power supplies and fiber gigabit uplinks • Ethernet Automatic Protection Switching (EAPS, RFC 3619) • Layer 2 and Layer 3 Extreme Standby Routing Protocol™ (ESRP) for dual-homed configuration Comprehensive Security for Control at the Edge of the Network • Wire-speed Layers 2 – 4 ACLs, web-based Network Login, 802.1x, SSH2, TACACS, RADIUS, DoS protection, MAC address security • Routing features for maximum forwarding control at the edge • Automatic Access Control List (ACL) and QoS classification with EPICenter® Policy Manager Summit48si from Extreme Networks® sets the standard for Layer 3 switching at the edge by maximizing 10/100 port density and architecting high levels of reliability while maintaining leadership in Layer 3 software features and performance. The unsurpassed software features, capacity and performance of Summit48si enable customers to provide more Layer 3 services to more users while using less space and at a lower Total Cost of Ownership than ever before. At one rack unit (1RU) in height, Summit48si packs 48 10/100 Ethernet ports and 2 Gigabit Ethernet ports with nonblocking capacity to support every port at full line-rate. This compact yet powerful package is capable of supporting two hot swappable load sharing power supplies—a reliability first in a 1RU Layer 3 switch. The reliability of Summit48si is enhanced even further with dual Gigabit Ethernet uplinks, both of which are active and can be aggregated for enhanced throughput and increased redundancy. Extreme Networks’ advanced Layer 3 software feature set, combined with dual hot-swappable power supplies makes Summit48si an unbeatable solution at the edge of the network. Target Applications • In enterprise markets—such as banking, manufacturing, education—where highperformance, reliability and security features are critical • Metro Ethernet access rings where granular bandwidth allocation, billing, and security are critical • Metro service providers that need high speed IP unicast and multicast services supporting carrier-class routing protocols like OSPF, BGP, and PIM-SM The unsurpassed software features, capacity, and performance of the Summit48si enable customers to provide more Layer 3 services to more users while using less space and at a lower Total Cost of Ownership than ever before. © 2009 Extreme Networks, Inc.
