1. Catalyst 2900XL/3500XL/2950 series switch port monitoring configuration Run the following command to configure a port listener:Port monitorFor example, F0/1 and F0/2 belong to the same VLAN1 and F0/1 Listen to ports F0/2 and F0/2:Interface

The emergence of Virtual lan vlan breaks the many inherent concepts of traditional networks, making the network structure flexible, convenient, and free to do as you like. VLAN divides user logic into working groups with relatively independent

Table of NAT features supported by Catalyst series switches 　 Note: The ipvs4000/4500 series switches of sup3/4 support the AGW module from 12.1 (13) EW. When the AGW module runs IOS 12.2 (13) T and later versions, you can use the AGM

In fact, the essence of a layer-3 switch is a layer-2 switch with the routing function. The routing mainly belongs to the network layer function in the OSI reference model, so the layer-3 Switch also has the routing kinetic energy. Now, we know that

Start the boot menu of the Huawei Switch configuration backup menu to restore switch data. Now, Huawei Switch configuration backup technology is gaining attention. Some people may not know what the Huawei Switch configuration backup is. It doesn't

Ethernet switches are still commonly used. So I studied the intelligent features of Ethernet switches and shared them with you here. I hope they will be useful to you. Enterprise applications are surging to Promote the Development of Ethernet

There are many things worth learning about SAN switches. Here we mainly introduce the precautions for choosing SAN switches. With the increasing number of network data and the frequency of network applications, many enterprises have begun to realize

The development of switch technology is very rapid. From the third-layer switch technology to the fourth-layer switch technology, the experience is very short, meeting more needs of users. When I first heard the word "Layer 3", I had some puzzles.

Flexibility, port density, and scalability are the biggest features of the Gigabit access switch. Therefore, we must carefully consider these parameters when purchasing them to suit our needs. The purpose of this evaluation is to make an objective

We all know that there are many reasons that affect the power consumption of LAN switches. For common users, we try our best to reduce the energy consumption. Many network equipment manufacturers today promise that their networks and switching

There are many things worth learning about the 10-ge switch. Here we mainly introduce the basic performance testing knowledge of the 10-ge switch. Network World recently conducted a 10-ge switch test on the 10-ge data center, analysis of vswitches

Optical SwitchIt ensures network reliability and provides a flexible signal routing platform. Although circuit switching is used in existing communication systems, in the future, all-optical networks require the pure optical switch system to

How can we make the home network more secure? In particular, users who use wireless broadband routers often experience virus attacks, network users, and account theft. In principle, we introduced the security threats faced by wireless home networks

Home wireless routers are the most widely used by home users. Here we will introduce a home wireless router with a high transmission rate, WHR-HP-G54-AP is a BUFFALO Product defined as "125M standard household wireless router and Wireless AP. This

There are still many things worth learning about Cisco router configuration. Here we will mainly introduce the details about Cisco router configuration. How to configure NAT Network Address Translation) so that computers on the Internet can access

A vswitch is not designed as a security device, but is still designed to improve network performance. If you want to add a vswitch to the security mechanism, make sure that you configure the vswitch correctly, second, the switch manufacturer must

When a LAN must have more than two CIDR blocks, hosts in different CIDR blocks are invisible to each other. To solve this problem, you must set a router between different network segments. If you spend tens of thousands of yuan to buy a router, it

The development of broadband routers in China is still very rapid. At the same time, there are a wide range of users. Many users are still very familiar with the parameters of some broadband routers, here I will give you a detailed explanation of
