American Cisco (Cisco System Inc.) switching products to “Catalyst” as a trademark include 2918, 2960, 3560, 3750 and a dozen series. In general, these switches can be divided into two categories:
One type is a fixed configuration switch, including most models of 3500 and below. For example, 1924 is a 24-port 10M Ethernet switch with two 100M uplink ports. In addition to limited software upgrades, these switches cannot be expanded; the other is modular switches, which mainly refer to models of 4000 and above. Network designers can select different number and type of interface boards and power modules according to network requirements. The corresponding software.
Common Cisco switches in network integration projects are the 1900/2900 Series, 3500 Series, and 6500 Series. They are used at the low, mid and high end of the network.
1, low-end products
The 900 and 2900 are typical of low-end products. The 1900 switch is suitable for desktop computer access at the end of the network and is a typical low-end product. It offers 12 or 24 10M ports and two 100M ports, of which 100M ports support full-duplex communication and provide up to 200Mbps port bandwidth. The backplane bandwidth of the machine is 320Mbps.
2, the mid-end products
The 3500 series in mid-range products is widely used and representative. The basic features of the C3500 series switches include backplane bandwidth up to 10Gbps and forwarding rate of 7.5Mpps. It supports 250 VLANs, supports IEEE 802.1Q and ISL trunking, supports CGMP network/Gigabit Ethernet switches, optional redundant power supplies, and more. However, the biggest feature of the C3500 is management and Gigabit. Management features aspects, C3500 achieved Cisco switching cluster technology, 16 can be C3500, C2900, C1900 series switches interconnected and managed from a single IP address. The switch can be easily configured and managed through the browser using the Cisco Visual Switch Manager (CVSM) software in the C3500. Gigabit characteristic aspects, C3500 full support Gigabit interface card (GBIC). There are three
1000BaseSX GBIC, suitable for multimode fiber, the maximum distance of 550m;
1000BaseLX / LH, multi-mode / single-mode fiber is suitable, the longest distance 10km; 1000BaseZX for single mode fibers, the longest distance 100km.
3, high-end products
For the enterprise data network, the C6000 series replaces the original C5000 series and is the most commonly used product. The Catalyst 6000 Series switches provide a high-performance, multi-layer switching solution for campus networks, designed for applications that require Gigabit expansion, high availability, and multi-layer switching, primarily for campus backbone connectivity. The Catalyst 6000 Series is comprised of Catalyst 6000 and Catalyst 6500 models, all of which are available in 6 or 9 slot models, 6006, 6009, 6506 and 6509, with the 6509 being the most widely used. All models support the same super engine and the same interface module, protecting the user’s investment. The main features of this series include high port density. Supports up to 384 10/100BaseTx adaptive Ethernet ports, 192 100BaseFX fiber Fast Ethernet ports, and 130 Gigabit Ethernet ports (GBIC slots).
