There are many things worth learning about the switch system. Here we mainly introduce how to reasonably configure the switch so that the switch system can control the network at will. With the rapid development of information technology, many organizations have established their own internal networks to cater to the information development trend, in the daily of
In a Cisco switch, how does one configure QOS speed limit? How to restrict BT download? This blog will use detailed examples for your explanation.
Instance 1: QOS speed limit problem on CISCO switches
It is used to control the bandwidth of a leased line user on a vswitch. The vswitch is usually at 10/100/1000 or three rates. QOS is required for other rates. You can also limit some ports, policy to restrict some ports.

Switch) performance directly affects the entire network. Therefore, it is not only necessary to understand the Switch parameters, but also helps you make better choices that meet your actual needs. Currently, the price of ATM switches remains high and is mainly used in backbone networks or wide area networks of large networks. Therefore, we will focus on Parameter Analysis of Ethernet switches.Selection of
Previous page Everyone talked about Cisco Basic Operation command switch, while dragon boat holiday, the Cisco simple switch configuration, and hope you share "Happy Dragon Boat Festival"! Ok, configure the switch, first, you must enter the global configuration mode switch, successfully connect the
Basic knowledge of VLAN division experiment: VLAN is short for Virtual Local Area Network (VLAN), which is a logical Network divided on a physical Network. This network corresponds to the L2 network of the ISO model. VLAN division is not limited by the actual physical location of the network port. A VLAN has the same attributes as a common physical network, except that it has no physical location restrictions. It is the same as a common LAN. Layer-2 unicast, broadcast, and multicast frames are f
The port of the core switch is mainly a fiber type, but the price of the switch fibre port is very expensive and requires special attention from the user, while the fibre port of the switch is not stacked and can only be used for cascading purposes.
Cascading can use either a normal port or a special mdi-ii port. A pass-through cable should be used when the two
The layer-4 switch is quite common. So I studied the practical application of the layer-4 switch and shared it with you here. I hope it will be useful to you. With the increasing popularity of Mbit/s, Gbit/s, and even Mbit/s local area networks, broadband MAN networks and even broadband wide area networks are widely used. Whether it is Intranet, exclusive, or residential intelligent networks, it is increasi
The following article describes the parameter configuration of the Ethernet switch. The switch can be divided into Layer 2 switches, Layer 3 switches, and Layer 4 switches according to the working protocol layer, you can divide network-managed switches and non-managed switches based on whether the network management function is supported.
Packet forwarding rate indicates the size of the packet forwarding ca
I. Lab Objectives
Master the configuration of the switch tag VLAN;
Master the basic configuration methods of layer-3 switches;
Measure the test taker's knowledge about how to configure VLAN routing for a layer-3 switch;
Layer-3 switches are used to implement inter-VLAN communication;
Ii. Lab background
An enterprise has two main departments: the technical department and the sales
The author office used a common two-layer switch, has been silent for us for several years, so far there has been no accident. However, recently, the author of the local area network computer room has a switch suddenly strange phenomenon; taking into account the particularity of the fault phenomenon, the author used a special method to exclude, now the specific troubleshooting process is written out, I hope
Mirror Port configurationMost switches support mirroring technology, which allows for easy troubleshooting of the switch. We call it "mirroring" or "Spanning". Mirroring is the copying of traffic from one port on the switch to the other (mirror port) for monitoring.CISCO3550 can be configured with 2 mirror portsCase: Mirroring Port 2~5 to Port 61. Mirror Port configurationSwitch>enableSwitch#conf T STEP3: C
In fact, the layer-4 switch is a network device, not a software network management system. It is mainly based on technology. In recent years, with the popularization of Mbit/s, Gbit/s, and even Mbit/s, the wide application of Broadband LAN and even Bandwidth WAN has driven the continuous development of switch technology.
In enterprise applications, the rapid development of Internet, the adoption of e-commer

The current limits of vswitches and vrouters have been deprecated, and some products generally combine the two. For a wireless switch, its access method is wireless, and its role is the exchange function. However, its advantages improve the network performance of enterprises. Next, we will introduce the advantages of wireless switch Management in WLAN.
The problem is that managing multiple access points is
The rapid development of wireless networks brings about more expanded network space. In a wireless network, a large wireless network will certainly have a wireless switch, so let's analyze the outstanding advantages of the wireless switch function. See what skills it has.
The problem is that managing multiple access points is an insurmountable situation for networks that may involve hundreds or thousands of
A repeater or hub cannot isolate a conflict domain and cannot isolate a broadcast domain, a bridge or a switch can only isolate a conflict domain from the broadcast domain, and the router can isolate the conflict domain and isolate the broadcast domain.ResolutionThe first thing to know is the conflict domain and broadcast domain, when a piece of network card send information, it is possible to conflict with another NIC network adapter is called the co
In the complex network environment today, the switch has become indispensable, so the switch manufacturers also develop quickly, here to take Cisco to give us a simple exchange! Cisco: Cisco; A simple introduction: Cisco is the world's leading provider of network solutions. Cisco's name is taken from San Francisco, where it is known as the world's Golden Gate Bridge. It can be said that, relying on its own
The core switch is still quite common, so I have studied the displaycpu command details in the switch. Here I will share it with you and hope it will be useful to you. In the LAN operating environment, the working status of core switch equipment is extremely important. It directly affects the efficient and stable operation of LAN networks. When a fault occurs in
