There are so many types of switches on the market, but do you know how they are divided into different types? Broadly speaking, there are two types of switches: WAN switches and LAN switches.

The basics of Cisco routers are also important. This article introduces the features and architecture of Cisco routers based on Cisco routers' network.

The main functions of the switch include physical addressing, network topology, error checking, frame sequence, and flow control. At present, the switch also has some new features, such as support for VLAN (Virtual Local Area Network), support for link aggregation, and even some have firewall functions.

For network devices, clearing running configuration information is the best way to prevent hackers from easily connecting to the corporate network. There are two different ways to clean the Cisco routers' running-config. Below we show you how to do it step by step.

The Cisco Catalyst 3850 Series is the latest enterprise-class stackable access-layer switches, it provides full convergence between wired and wireless on a single platform.

As we all know, the 10G fiber networks are already common in telecommunication networks, and 10G switches are being widely used by users. According to statistics, Cisco switches are the most common one. If you are using a Cisco switch, you will need to select a Cisco compatible optical module, such as an SFP optical module or an SFP+ optical module. If you don't know how to transfer between optical and electrical signals, please read the following carefully and it will help you.

As we all know, the Internet has been perfectly integrated with our life, so we can't leave the switch now, without it we can't use many of the features on the Internet. As long as there is a switch, any two network nodes can exchange information. It is with the switch that we have such a rich Internet life.

​There are so many kinds of switches in the market, which one should we buy? For most companies, they only need to buy SMB Switches. How do I choose the right SMB Switches? Below is the comparison among access switch, aggregation switch and core switch.

A switching loop or bridge loop occurs in computer networks when there is more than one Layer 2 (OSI model) path between two endpoints (e.g. multiple connections between two network switches or two ports on the same switch connected to each other). The loop creates broadcast storms as broadcasts and multicasts are forwarded by switches out every port, the switch or switches will repeatedly rebroadcast the broadcast messages flooding the network. Since the Layer 2 header does not support a time t

ACL access control lists are indispensable for building a security-compliant network, but configuring ACLs on Layer 3 switches is not known to some of the primary network administrators who are new to the enterprise. The following describes the test process for how to configure an ACL on a Cisco Layer 3 switch.

In today's society, the Internet has become an indispensable thing for everyone. Everyone's life is closely related to the Internet. As long as there is a switch, any two network nodes can exchange information. It is with the switch that we have such a rich Internet life. There are also many brand models of the switch. Here we tell you the advantage and disadvantage of WS-C2960-24TC-L.

As an innovative product, the Cisco 3750 switch plays an important role in many places. It is positioned at the enterprise switch and has excellent performance in terms of performance parameters and function settings. We may encounter some problems during the actual use. The following is about how to troubleshoot the Cisco 3750 series switches.
