Коммутатор L3, 48 портов 10/100BASE-T, 4 порта 1000BASE-X (SFP)
Коммутаторы семейства Cisco Catalyst 3560 - это линейка коммутаторов корпоративного класса с фиксированной конфигурацией (в конфигурациях Fast Ethernet и Gigabit Ethernet предусмотрено питание устройств по витой паре (PoE), совместимое со спецификацией IEEE 802.3af и до-стандартным вариантом Cisco). Они предназначены для локальных сетей небольших предприятий или удаленных офисов и отлично подходят на роль коммутатора сети доступа. Эти коммутаторы уровня доступа идеально подходят для локальных сетей доступа предприятий и филиалов. Благодаря поддержке портов 10/100/1000 Мбит/с и технологии PoE, превосходной производительности и защите инвестиций, устройства позволяют развертывать новые приложения, такие как IP-телефония, беспроводной доступ, видеонаблюдение, системы управления зданиями, а также пункты удаленного обслуживания с видеосвязью.
 
Оборудование позволяет сохранить простоту традиционной коммутации локальных сетей и при этом развернуть интеллектуальные сетевые сервисы, такие как:
  • Мощная система управления качеством обслуживания (QoS)
  • Ограничение скорости передачи данных
  • Списки контроля доступа (ACL).
  • Управление мультивещанием
  • Высокопроизводительная IP-маршрутизация
Коммутаторы Cisco Catalyst 3560 поставляются с образами ПО IP Base и IP Services, которое может быть модернизировано до версии Advanced IP Services.  Программное обеспечение IP Base (ранее известное как Standard Multilayer Image или SMI) включает мощную систему управления качеством обслуживания, ограничение скорости передачи данных, списки контроля доступа, а также базовые функции маршрутизации и IPv6. Программное обеспечение IP Services (ранее известное как Enhanced Multilayer Image или EMI) предоставляет дополнительные функции корпоративного класса, включая аппаратно реализованные функции маршрутизации одноадресных и мультивещательных IP-пакетов, а также маршрутизацию на основе политик (PBR). ПО Advanced IP Services включает поддержку маршрутизации IPv6 и списков контроля доступа IPv6.

Features and Benefits of Cisco Catalyst 3560 Series

Feature

Benefit

Ease of Use and Deployment

 Cisco Express Setup simplifies initial configuration with a Web browser, eliminating the need for more complex terminal emulation programs and CLI knowledge.

 IGMP filtering provides multicast authentication by filtering out nonsubscribers and limits the number of concurrent multicast streams available per port.
 Multicast VLAN registration (MVR) continuously sends multicast streams in a multicast VLAN while isolating the streams from subscriber VLANs for bandwidth and security reasons.

QoS and Control

Advanced QoS

 Standard 802.1p CoS and DSCP field classification are provided, using marking and reclassification on aper-packet basis by source and destination IP address, source and destination MAC address, or Layer 4 TCP or UDP port number.
 Cisco control- and data-plane QoS ACLs on all ports help ensure proper marking on a per-packet basis.
 Four egress queues per port enable differentiated management of up to four traffic types.
 SRR scheduling helps ensure differential prioritization of packet flows by intelligently servicing the ingress and egress queues.
 Weighted tail drop (WTD) provides congestion avoidance at the ingress and egress queues before a disruption occurs.
 Strict priority queuing guarantees that the highest-priority packets are serviced ahead of all other traffic.
 There is no performance penalty for highly granular QoS functions.

Granular Rate Limiting

 The Cisco Committed Information Rate (CIR) function guarantees bandwidth in increments as low as 8kbps.
 Rate limiting is provided based on source and destination IP address, source and destination MAC address, Layer 4 TCP and UDP information, or any combination of these fields, using QoS ACLs (IP ACLs or MAC ACLs), class maps, and policy maps.
 Asynchronous data flows upstream and downstream from the end station or on the uplink are easily managed using ingress policing and egress shaping.

 IP source guard prevents a malicious user from spoofing or taking over another user's IP address by creating a binding table between the client's IP and MAC address, port, and VLAN.
 DHCP Interface Tracker (Option 82) augments a host IP address request with the switch port ID.
 Port security secures the access to an access or trunk port based on MAC address.
 After a specific timeframe, the aging feature removes the MAC address from the switch to allow another device to connect to the same port.
 Trusted Boundary provides the ability to trust the QoS priority settings if an IP phone is present and to disable the trust setting if the IP phone is removed, thereby preventing a malicious user from overriding prioritization policies in the network.
 Multilevel security on console access prevents unauthorized users from altering the switch configuration.
 The user-selectable address-learning mode simplifies configuration and enhances security.
 BPDU Guard shuts down Spanning Tree Protocol PortFast-enabled interfaces when BPDUs are received to avoid accidental topology loops.

 IGMP filtering provides multicast authentication by filtering out nonsubscribers and limits the number of concurrent multicast streams available per port.
 Dynamic VLAN assignment is supported through implementation of VLAN Membership Policy Server (VMPS) client functions to provide flexibility in assigning ports to VLANs. Dynamic VLAN helps enable the fast assignment of IP addresses.
 Cisco Network Assistant software security wizards ease the deployment of security features for restricting user access to a server as well as to a portion of or the entire network.
 Two thousand access control entries (ACEs) are supported.

Manageability

Superior Manageability

 For enhanced traffic management, monitoring, and analysis, the Embedded Remote Monitoring (RMON) software agent supports four RMON groups (history, statistics, alarms, and events).
 Layer 2 traceroute eases troubleshooting by identifying the physical path that a packet takes from source todestination.
 All nine RMON groups are supported through a SPAN port, which permits traffic monitoring of a single port, a group of ports from a single network analyzer or RMON probe.
 Domain Name System (DNS) provides IP address resolution with user-defined device names.
 Trivial File Transfer Protocol (TFTP) reduces the cost of administering software upgrades by downloading from a centralized location.
 Network Timing Protocol (NTP) provides an accurate and consistent timestamp to all intranet switches.

 The easy-to-use graphical interface provides both a topology map and front-panel view of the switch.
 Cisco AVVID (Architecture for Voice, Video and Integrated Data) wizards need just a few user inputs to automatically configure the switch to optimally handle different types of traffic: voice, video, multicast, andhigh-priority data.
 A security wizard is provided to restrict unauthorized access to applications, servers, and networks.
 Upgrading the Cisco IOS Software on Cisco Catalyst switches is a simple matter of pointing and clicking, with one-click upgrades.
 Cisco Network Assistant supports multilayer feature configurations such as routing protocols, ACLs, and QoS parameters.
