Henan total generation supply Cisco Cisco? Catalyst? 2918 Series Switches

Cisco? Catalyst? 2918 Series switches are for the Chinese market of small and medium-scale network deployment of entry-level fixed-configuration switches. Catalyst 2918 in Simplified Chinese equipment panel and graphical interface to privileged price for the entry-level inter-wiring that provide desktop Fast Ethernet and Gigabit uplink Fi and a small branch offices. Cisco Catalyst 2918 Series by providing a complete entry-level security policies, quality of service (QoS) and availability features to reduce the cost of enterprise network ownership. The switches also for Chinese enterprises to provide users with a way from non-intelligent hubs and unmanaged switches to scalable managed network migration easy. Cisco Catalyst 2918 switches provide: includes two 10/100/1000 Ethernet ports, each uplink port has one 10/100/1000 Ethernet port; based 10/100/1000 copper Ethernet ports for the user, port and MAC addresses provide secure network access control configuration uses automatic configuration Smartports enhanced fault exclusion for the link connection problems and cable diagnostics capability to provide excellent quality of service, multicast service limited lifetime hardware warranty fast network-based graphical interface Chinese Free software update configuration Cisco Catalyst 2918 Series switches consists of the following switches (see Figure 1): Cisco Catalyst 2918-24TT-C: 24 10/100 Ethernet ports and two 10/100 / 1000BAST-T uplink port Cisco Catalyst 2918 -24TC-C: 24 10/100 Ethernet ports and two dual-purpose uplink port (10/100 / 1000BASE-T or SFP) Cisco Catalyst 2918-48TT-C: 48 10/100 Ethernet ports and 2 10/100 / 1000BAST-T uplink port Cisco Catalyst 2918-48TC-C: 48 10/100 Ethernet ports and two dual-purpose uplink port (10/100 / 1000BASE-T or SFP) SFP-based Gigabit Ethernet port supports Cisco 1000BASE-SX, 1000BASE-LX and 100BASE-FX SFP transceiver. Security Features Security Cisco Catalyst 2918 switches support can help businesses protect important information, so that unauthorized users can not access the network, ensure privacy, and maintain uninterrupted operation. Using 802.1x standard allows dynamic, port-based security, providing user authentication. Port security based on the MAC address of the device to restrict access to the Ethernet port, and by controlling the number of devices connected to each port of the switch from MAC flooding attacks, to ensure access to the user's legitimacy. Availability and scalability of Cisco Catalyst 2918 switches multicast filtering and enhanced by a full set of Spanning Tree Protocol (Spanning Tree Protocol, STP), to achieve the network scalability and higher availability. Standard Spanning Tree Protocol (STP) of improvements, such as PVST +, UplinkFast and PortFast, to achieve maximum network uptime. PVST + can perform Layer 2 load sharing on redundant links to efficiently use the extra capacity in a redundant design. UplinkFast, PortFast, and BackboneFast all greatly reduce the standard of 30-60 seconds Spanning Tree Protocol convergence time. The loop guard and bridge protocol data unit (BPDU) guard enhancements provide Spanning Tree protocol to avoid loops. Multilayer QoS features Quality of Service provided by the Cisco Catalyst 2918 switch to ensure that the network traffic classification and prioritization, and the best way to avoid network congestion. Cisco Catalyst 2918 Series switches use 802.1p (CoS) for traffic group classification. Cisco Catalyst 2918 switch supports four output queues per port. In exports, the switch performs scheduling and congestion control. Cisco Catalyst 2918 Switch supports Shaped Round Robin (Shaped Round Robin, SRR) and strict priority queuing. SRR algorithm helps ensure prioritization. Administrative user can select a graphical interface based on Chinese Web browser to set up the switch without terminal emulation programs and the command-line interface (CLI). Fast setting allows no technical knowledge of staff simply and quickly set up the switch, thereby reducing deployment costs. Table 1 provides the features and advantages of Cisco Catalyst 2918 switches. Table 2 gives the hardware specifications, power specifications in Table 3 and Table 4 lists the management standard, Table 5 provides the safety and compliance information.
