Progressive Features All Allied Telesis' Layer 3 switches come with the feature rich operating system AlliedWare, which includes Layer 3 IP Static Routing, RIP, RIPv2,VRRP and OSPFv2 routing protocols. For advanced networking applications Allied Telesis offers the Rapier 'i' series with three optional feature licenses: Full Layer 3 upgrade, Advanced Layer 3 upgrade, and Security upgrade. The Full Layer 3 upgrade enables a set of additional routing protocols such as IPX, DVMRP, VRRP, PIMDM/ SM and RSVP. The Advanced Layer 3 upgrade provides a set of the specialized protocols consisting of IPv6, BGP4, and Load Balancer. The Security upgrade offers an ICSA- certified Stateful Inspection Firewall as well as both SMTP and HTTP application gateways. WAN Support - Rapier Switch/Router The Rapier 16fi and 24i models support an optional Network Services Module (NSM) with a variety of Port Interface Cards (PICs) to provide Wide Area Network connectivity for E1,T1,PRI ISDN,BRI ISDN,Asynchronous and Synchronous communications, Frame Relay and X.25.The AlliedWare operating system provides Layer 3 IP static routing, RIP, RIPv2,VRRP and OSPFv2 routing protocols, while optional specialized protocols are also available such as BGP4, IPX, RSVP and the multicast routing protocols of DVMRP and PIM-DM/SM.These routing features give the Rapier 16fi and 24i the ability to not only act as a managed Layer 3 switch, but also as a fully specified router with four WAN interfaces. Switching Features The Rapier 'i' series of switches are some of the most powerful switches on the market. All Rapier 'i' Layer 3 switches include a suite of advanced switching features such as IEEE 802.1Q VLAN Tagging, IGMPv2, 802.1p Traffic Prioritization of packets at Layer 3 and Layer 4, and broadcast and multicast traffic control.The Quality of Service (QoS) features offered by the Rapier 'i' series are particularly useful for multi- tenant unit, multi business unit,Telco, or Network Service Provider applications. Return on Investment Today's economy demands that network investments provide a Return On Investment sooner rather than later. Cost effectiveness is achieved three ways. First, Rapier 'i' is the first Layer 3 switch with an integrated WAN router. Networks using a Layer 3 switch that does not support WAN routing need to incorporate additional router equipment at extra expense. Second, Rapier 'i' has three optional feature licences so you only pay for the specialized features you need. Third, the Rapier 'i' series of switches offer the greatest variety of uplinks at the lowest cost. Key Features • Wirespeed Layer 2 - Layer 7 filtering • Wirespeed Layer 3 IP routing • Wirespeed Layer 2 switching • Non-blocking at full line rate for all packet sizes (Rapier 16fi & Rapier 24i) • Port trunking with link aggregation • Stacking with open standards based interfaces • Stateful Inspection Firewall • BGP-4 option • IPv6 option • Load Balancer option • Support up to 255 VLANs • Private VLANs • Bandwidth limiting • Broadcast and multicast traffic control • MVR • IPsec • L2TP • IP RIP v1 and v2 • OSPF v2 • VRRP • TACACS+ • 802.1x • SNMPv3 • 2 uplink bays • DHCP snooping • DHCP option 82 Allied Telesis RAPIER 'i' SERIES | WAN Capable Layer 3 Fast Ethernet Switches Choose from 100FX, copper Gigabit, or fiber Gigabit modules. Alternatively, choose unpopulated GBIC module and populate it with one of five GBIC types from Allied Telesis. The Rapier 'i' series offers an unmatched combination both switching and routing capabilities coupled with a flexible set of specialized features and uplink options. Fabulous Fiber With 16 fiber 100FX ports the Rapier 16fi is uniquely suited to demanding environments where not only the full-feature richness and switching performance of the Rapier 'i' switch is needed, but also where cable security and electro-magnetic immunity (EMI) are considerations. As well as performing under these demanding environments the 16fi offers the flexibility to provide access to the end station or to perform as an aggregation device. Due to the exceptional cable length afforded by 16fi's 100FX ports, networks that require an aggregation switch that provides routing between distant sites of up to 2000 meters can be comfortably met. IPv6 - The Future Don't be shut out of the next generation of the Internet Protocol, IPv6.The Rapier series enables networks to take advantage of IPv6's important benefits: • Addresses are 16Bytes long in contrast to IPv4's 4Byte addresses. • Globally unique addresses with more levels of addressing hierarchy, to reduce the size of routing tables. • Auto-configuration of addresses by hosts. • Improved scalability of multicast routing, by adding a 'scope' field to multicast addresses. • A new type of address, the 'anycast address,' which is used to send a packet to any one of a group of devices. Bandwidth Limiting All Rapier 'i' series switches come with asymmetric bidirectional bandwidth limiting, per p...
