Gigabit Ethernet Gigabit Ethernet speed of 1000Mbps, providing bandwidth to meet growing demand for the new network, eliminating bottlenecks, improve performance, and increase the return on investment in existing infrastructure. The current staff put a higher demand on the network, you need to run multiple concurrent applications on the network. For example, an employee to attend a group meeting by IP video conference call, send a spreadsheet to participants of 10MB for the entire team broadcast the latest marketing video for the team to evaluate, and queries the customer relationship management database to get the latest real-time feedback. Meanwhile, in the background to start a multi-gigabit system backup procedures, and provide the latest anti-virus files on the client. Cisco Catalyst 3560 provides a way for users to existing Category 5 copper network intelligence will be expanded to 1000Mbps, and simultaneously support PoE, for maximum productivity and investment protection. Network intelligence Today's networks are evolving at the network edge four new trend emerged: the desktop computing power bandwidth-intensive applications with high sensitive data extension is present a variety of device types in the network, such as IP phones, wireless LAN access In and IP video cameras These new demands have been working with a number of tasks critical applications competing for resources. Thus, IT professionals must be regarded as the key to effective network edge to provide management information and applications are. As companies increasingly rely on networks as a strategic business infrastructure, ensure high network availability, security, scalability, and its comprehensive control is more important than ever. By adding Cisco intelligent functionality to the wiring closet, customers can now deployed throughout the network of intelligence services that consistently meet from the desktop to the core and through the WAN requirements. By Cisco Catalyst Intelligent Ethernet switches, Cisco helps companies get added to its full advantage of network intelligence service. To further optimize network operations, the deployment has the following characteristics function is crucial: to make high-availability network infrastructure to meet time-critical needs, scalable to accommodate company growth, high-security to protect confidential information, and capable of differentiating and controlling traffic. Enhanced security with a wide range of security features Cisco Catalyst 3560 Series offers, businesses can protect important information, prevent unauthorized access to the network, ensure privacy, and maintain uninterrupted operation. Cisco Identity-Based Network Services (IBNS) provides authentication, access control and security management features to protect the network connections and resources. Cisco Catalyst 3560 Series Cisco IBNS prevent unauthorized access, and ensure that users get only their designated rights. Specific levels can dynamically manage network access. Using 802.1x standard and the Cisco Access Control Server (ACS), regardless of where the user is connected to the network can be assigned to a VLAN in verification or ACL basis. This setting enables IT departments can not affect users in the case of mobility with the lowest administrative overhead to implement strong security policies. In order to prevent denial of service attacks and other attacks, according to the available ACL source and destination MAC address, IP address or TCP / UDP port to reject packets to restrict access to sensitive portions of the network. ACL inquiry done in hardware, so when implementing ACL-based security does not affect the forwarding performance. Port security in accordance with the Ethernet port is connected to the device's MAC address to restrict access to this port. It can also be used to limit the insertion of a switch port of the total number of devices, so the switch will not be MAC flooding attacks, and reduces the risk of malicious wireless access point or access concentrator. Dynamic Host Configuration Protocol (DHCP) monitor, can not only allow users to port trust DHCP requests (but not responses) for transmission, which prevents the DHCP spoofing. In addition, DHCP Interface Tracker (Option 82) adds a host IP address request with the switch port ID, which allows for precise control of the IP address. On the basis of DHCP snooping on, can prevent IP address spoofing through dynamic ARP inspection, and IP source guard. MAC address notification feature can send an alert to a management station, which monitor the network and track users so network administrators know when users, where access to the network. Private VLAN feature isolates ports on the switch, helping to ensure that traffic flows directly from the entry point to the aggregation device through a virtual path, but not sent to another port. Secure Shell (SSH) protocol version 2, Kerberos and SNMP version 3 (SNMPv3) encrypt information management and network management, network protection against interference or eavesdropping. TACACS + or RADIUS authentication enables centralized access control of the switch and restrict unauthorized users from changing configuration. In addition, you can configure local username and password database on the switch. 15 authorization level switch on the console and two levels on the Web management interface provides the ability to assign different levels of configuration capabilities to different administrators. Availability and scalability of Cisco Catalyst 3560 Series is equipped with a powerful set of features through IP routing and is designed to provide a second layer of network availability of a full set of Spanning Tree Protocol highest improvement, network scalability and higher availability. Cisco Catalyst 3560 Series provides high-performance hardware-based IP routing. The Cisco Express Forwarding-based routing architecture to improve scalability and performance. This architecture can be very high speed search in ensuring the stability and scalability, while sufficient for future requirements. In addition to supporting dynamic IP unicast routing outside, Catalyst 3560 series also for the perfect configuration for the network need multicast support. Hardware Protocol Independent Multicast (PIM) and Internet Group Management Protocol (IGMP) makes Catalyst 3560 Series switches become ideal for intensive multicast environments. Routed uplinks to the core can achieve faster failover protection, and by terminating all Spanning Tree instances aggregation switches to simplify the spanning tree protocol algorithm to improve network availability. If an uplink fails, by Shortest Path First (OSPF) or Enhanced Interior Gateway Routing Protocol (EIGRP) and other scalable routing protocol, it can quickly failover to the redundant uplink, rather than relying on standard Spanning Tree Protocol convergence. Using a routing protocol packet after a link failure redirect, using the second layer spanning enhanced features compared to solutions, failover faster. Additionally, routed uplinks to implement the equal cost routing (ECR) to perform load balancing, can make better use of bandwidth. Routed uplinks eliminating unnecessary broadcast data flows into the network backbone, optimizing the utilization of the output wiring closet uplink. Catalyst 3560 as a multicast environment wiring closet switches, but also saves a lot of bandwidth. Use routing uplinks to the network core, there is no need to transport multiple streams of the same multicast from the upstream content servers to LAN access switches. For example, three users are assigned to three separate VLAN, they want to browse multicast ABC, assume that the switch does not route the wiring closet uplinks, we must start from the upstream router to the wiring closet switch transmission ABC three multicast streams. Catalyst 3560 switches will enable users to deploy IP routing to the core to create a scalable, superior multicast network performance. Cisco Advanced IP Services license offers IPv6 routing and IPv6 ACL support, including dual IP stack (synchronous IPv4 and IPv6) forwarding support. IPv6 protocols supported include RIP next generation (RIPng), OSPFv3 and static routing. Improvements to the standard Spanning Tree Protocol, such as Per-VLAN Spanning Tree Plus (PVST +), Uplink Fast, and PortFast, can achieve maximum network uptime. PVST + allows for Layer load sharing on redundant links to efficiently use the extra capacity in a redundant design. Uplink Fast, PortFast, and BackboneFast all greatly reduce the standard of 30-60 seconds Spanning Tree Protocol convergence time. Loop guard and bridge protocol data unit (BPDU) protection to avoid the Spanning Tree Protocol loop. Advanced QoS Cisco Catalyst 3560 offers superior multilayer, detailed QoS features to help ensure that network traffic classification and prioritization, and the best way to avoid the congestion. QoS configuration through automatic QoS (Auto QoS) greatly simplified, which is a feature that detects IP phone and automatically configure the switch for the appropriate classification and egress queuing. This optimizes traffic prioritization and network availability, and will not bring complex configuration problems. Catalyst 3560 can classify incoming packets, re-classification, regulatory, labeling, sorting and scheduling, and is able to packet sequencing and scheduling at the exit. Packet classification enables network elements can distinguish different traffic flows and enforce policies based on the second layer and the third layer QoS. To achieve QoS, Catalyst 3560 series switches first acknowledgment packet or traffic group, and then use the Differentiated Services (DSCP) field or the 802.1p service level (CoS) field of classification and re-classification of these groups. Classification and reclassification can be based on source or destination IP address, source or destination MAC address, or Layer 4 TCP / UDP port and other standards. In the entrance, Cisco Catalyst 3560 will also be monitored to determine the packet is pre-defined in the policy, in order to change the grouping label tag, transport or disposal group packets and packets sorted by category. All ports support the control plane and data-plane ACL, ensure that each packet is handled properly. Catalyst 3560 each port has four output queues, allows network administrators to better divide, for a variety of applications assigned priority on the LAN. In exports, the switch performs scheduling and congestion control. Scheduling is a method of determining the order queue processing algorithm or process. Catalyst 3560 series switches support shaping cycle (SRR) and strict priority ordering. SRR algorithm helps ensure personalized prioritization. These QoS features allow network administrators to be able to mission-critical and bandwidth-intensive traffic classified as a higher priority, including enterprise resource planning (ERP) (Oracle, etc.), voice (IP telephony traffic), and computer-aided design (CAD) or computer-aided manufacturing (CAM), etc., and the less time-sensitive applications, FTP or e-mail classified as lower priority. For example, downloading a large file to the wiring between a port of the switch, and this will also increase the delay for this destination to another port on the switch voice traffic, this situation is extremely user wants to see. By ensuring that voice traffic is properly classified and prioritization on the network, you can avoid this situation. And Web browsing, and other applications can be treated as a lower priority and treated with "into best effort" basis. Cisco Catalyst 3560 Series through the committed information rate (CIR) support functions and perform rate limiting. Through CIR, it can be guaranteed in increments as low as 8kbps bandwidth. Allocate bandwidth based on several criteria, including MAC source address, MAC destination address, IP source address, IP destination address, and TCP / UDP port number. When the required service level agreements or Network Manager network environment need to control certain users bandwidth, bandwidth allocation is very important. Manage new Cisco Express Setup feature (Cisco Express Setup) simplifies the initial configuration of the switch. Users can now choose to set up the switch through a Web browser, without the need for more complex terminal emulation programs and the command-line interface (CLI) understanding. Fast setting allows no technical knowledge of staff simply and quickly set up the switch, thereby reducing deployment costs.
