    From Wikipedia: The term layer 3 switch is a bit misleading because it is a multi-function device that is a combination of router and switch. The term Layer-3-Switch usually stands for further developed high-performance switches, which have been extended to include TCP / IP routing functionality (and vice versa). Layer 3 switches are used in areas where, above all, high performance (high data throughput of the router) is required. The emphasis on switch functionality has its roots in marketing, not wanting to be associated with (at least according to marketing beliefs) old-fashioned, complicated and clumsy routers (and their manufacturers).
    The inexhaustible possibilities of the Summit48si meet the requirements of many applications, both in corporate and metro networks.
    Extreme Networks Summit48si sets the new standard for layer 3 switching at the network edge. Its highlights are the maximized 10/100 port density, extremely high reliability and the provision of Layer 3 software functions and performance. The robust software functions, coupled with the capacity and performance of the Summit48si, allow layer 3 services to be provided to more users with less space requirements - with the result of lower overall costs.
    In just a 4cm height unit (1U) of the Summit48si there is space for 48x 10/100 Ethernet ports and 2 Gigabit Ethernet ports. The non-blocking technology supports each port at full line speed. This compact and yet extremely powerful system can be fed via two hot-swap power supplies with load balancing - a level of reliability previously unknown for a layer 3 switch of this size. Another reliability feature of the Summit48si are the dual Gigabit Ethernet uplinks, both of which are active and can be bundled if necessary to increase throughput and redundancy.
    Extreme Networks ' collection of highly developed Layer 3 software functions, coupled with the redundant, hot-swap power supplies, make the Summit48si the perfect solution for use at the edge of the network.
    In industries - such as banking, manufacturing, education - where high performance, reliability and security standards are required Metro Ethernet access rings, where precisely coordinated bandwidth allocation, billing and security are essential Metro service providers providing unicast and multicast IP services in high speed with carrier routing protocols such as OSPF, BGP and PIM-SM

    Quality of Service and Application Flexibility
    Maximum performance
    With industry-leading performance for the most demanding applications, Summit48si has a non-blocking architecture with 17.5 gigabits of throughput with
    wire-speed performance on every port. Bidirectional rate shaping allows you to manage bandwidth on Layer 2 and Layer 3 traffic flowing both to and from the switch. DiffServ and 802.1p deliver varied levels of service for time-sensitive, demanding applications for voice, video and data and ensure efficient bandwidth usage. Eight hardware queues provide granularity for multiple applications, and guarantee low latency / low jitter for time sensitive applications (voice and
    multimedia) with support for advanced scheduling algorithms.
    Application flexibility
    Summit48si features a 128K routing table size for maximum forwarding control at the edge with the same advanced feature set supported end-to-end throughout the customer's network. Protocol-based VLANs enable the network administrators to define a packet filter that the switch uses as the matching criteria to determine if a particular packet belongs to a particular VLAN. Virtual MANs (vMANs) feature is useful in building transparent private networks that need point-to-point or point-to-multipoint connectivity across an Ethernet infrastructure. Policy-Based QoS with 8 queues per port, bidirectional rate shaping and bandwidth management provides the ability to prioritize mission-critical applications and traffic to deliver maximum productivity and deliver delay-sensitive applications such as voice and video.
    High network availability
    Redundant hot-swappable power supplies, and fiber gigabit uplinks provide true high availability as Summit48si immediately is able to failover to the redundant port and the user's application is unaffected. The user stays connected to the network and remains productive. Summit48si delivers connectivity and productivity with advanced high availability features, such as EAPS (RFC 3619) with multidomain support to deliver subsecond (less than 50ms recovery) protection switching to interconnected switches in an Ethernet ring topology. EAPS is similar to Spanning Tree Protocol (STP), but offers the advantage of converging in significantly less time than STP or even Rapid Spanning Tree (802.1w) when a link breaks in the ring. ESRP can be implemented at both Layers 2 and 3 and extends the Virtual Redundant Redundancy Protocol's (VRRP) capabilities, adding Layer 2 resiliency and loop prevention and Layer 3 default router redundancy.
    Equal Cost Multipath (ECMP) allows the networks to be even more resilient as multiple equal-cost routes can be used concurrently to an end destination.
    With the software redundant port feature, a specified primary port can be backed up by another port. Should the link go down on the primary port, the redundant port will establish link and become active. Thus multihomed redundancy can be easily designed without the complexity of a protocol.
    Comprehensive Security for Control at the Edge of the Network
    With IEEE 802.1x login, network managers can always control who is connected to the network and prevent unauthorized clients from gaining access to the network. Web-based Network Login does not require any specific client software and can work with any https-compliant web browser and thus is independent of
    platform. Every user on every port can be authenticated so the network is protected at the most sensitive point of attack. MAC address security allows identifying port abuse such as rogue wireless access points or hubs / switches on edge ports. It includes two features: lockdown on a per port basis and limiting the number of MAC addresses learned by a port. Lockdown and saving learned MAC addresses between reboots can be used to protect dedicated ports for VoIP phones or printers from abuse. Limiting the number of MAC addresses learned on a port also allows enforcement of service level agreements in tenant or service provider environments. SSHv2 allows network managers to securely configure the box remotelywithout any risk of packet snooping or man-inthe-
    middle attack. SSHv2, DoS protection, TACACS + and RADIUS bring reliable secure configuration traffic (encryption) and authentication. Scanning of malicious users or virus-infected end-clients can cause the Forwarding Database (FDB) table to fill up very quickly and FDB replacements to happen at a higher rate. The attacks can hurt the quality of internal traffic significantly, if all Layer 3 forwarding is made by host lookup. The IPDA SUBNET lookup feature forces the attack traffic to use the IPFDB SUBNET forwarding table instead of the host forwarding table. This feature is intended to decrease frequency of FDB collision and replacement and accelerate packet forwarding for Summit48si. Multiple Supplicant (client) enables multiple clients to be individually authenticated on the same port. Summit48si has wire-speed layers 2 - 4 ACLs on every port for maximum security while maintaining maximum throughput.
