At present, the modular multi-layer switch is widely used. Many people may not understand the comprehensive explanation of the modular multi-layer switch. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. Cisco Systems, the world's leading network equipment vendor, recently anno

that your server operations are too slow. Check your desktop traffic speed and network switching capability. Question 4: Maybe tomorrow, the business will double, and the demand for various network applications will double. Are you ready for the network? Simplifying management and reducing costs are the pursuit of network managers. The network environment is a complex and closely composed environment, and you will find that the network is becoming more and more picky. Remember, the network has

effectively inhibiting the generation of broadcast storms. With the rapid development of China's enterprise network, campus network and broadband construction, the application of layer-3 switches has penetrated from the initial backbone layer and convergence layer to the edge access

determines which VLAN to assign the port to. This approach has great advantages, but creating a database is a very difficult and tedious task. Here is an example of how to implement a VLAN in a typical Fast Ethernet LAN. A typical LAN refers to a core switch with a three-layer switching function to connect several branch switches (not necessarily three-layer s

exchange chip that can generate Gigabit and MB ports; one is a CrossBar chip that only outputs Internal High-Speed interfaces (usually at a rate of over 10 Gbit/s) for interconnection between modules. Currently, Cisco, Extreme,, gangwan, and other vendors have launched CrossBar-based core switch products. However, many products on the market still use gigabit port interconnection, it is mainly intended for users with high performance requirements and

switches are generally 10 M, M Adaptive, and the network card will also buy M, use twisted pair wires to connect the network card with any port of the switch, install the TCP/IP protocol. First, configure two IP addresses on one network card to go To the TCP/IP protocol attribute, and click "Use the following IP Address:" to enter one of the allocated IP addresses and mask, next, click "advanced" and click "add" under "ipsettings-IP Address" to enter

Layer-3 switches are quite common, So I studied how layer-3 switches can ensure network security. Here I will share with you, hoping to help you. A high-performance switch Cisco Catalyst 4006 with multiple 1-gigabit ports and 10-Gigabit ports is placed in the center of the s

slows down significantly. Some access layer switches and some small routers even crash, and the CPU usage of the core layer-3 switch reaches 100%, the operator has to Block ICMP packets. Broadcast exception packets: broadcast is a necessary way to implement certain protocols. Broadcast packets are sent to all hosts in a specific network segment. Each host proces

At this time, selecting a access layer switch with QoS function can solve the urgent needs of network administrators to some extent. The sixth is the Web management interface. The Web interface configuration and management are very

configuration, the MAC address can be acquired to the specified IP every time, and only the specified IP address can be networked. Configuring IP-MAC bindings on layer three switches is relatively complex to configure and maintain. In fact, there is a way to enable DHCP on the gateway to each VLAN. Ip-mac bindings are made directly on the gateway. Please continue reading:2. Three

The Cisco layer-3 switch is another core switch developed by Cisco. It aggregates the bandwidth of the backboard of the switch that is stacked together, in this way, the total backplane of the switch stack is the sum of the bandwidth of several stack switches. Note that not only the ports used are different, but the ca

High intelligence, high availability, and high reliability are the characteristics of multi-layer intelligent optical fiber switch. Although its technology is not very mature yet, it has been recognized by people. Cisco Systems recently announced that it will launch the CiscoMDS9100 series of multi-layer smart Optical Fiber s
