the manufacturer's engineers or other professional personnel for configuration. Therefore, it is difficult for these network administrators of small and medium-sized enterprises to have the opportunity to manually configure a switch. The process of vswitch configuration skills is complex, and the specific vswitch configuration skills vary with different brands and series of vswitches. This article only teaches you how to configure general-purpose vswitches, with these general-purpose Switch con

Today's recommendation: cisco switch module Ethernet application details, familiar with the following cisco switch module knowledge point, you only need to spend a few minutes to understand the cisco switch Module Settings. There is also a diagram below, and other related information will be mentioned in this article. As an important cisco switch modular multi-layer switch, the Catalyst 6500 series provides secure fusion services for cabling rooms, co

Understanding layer-3 Interfaces Layer-3 interfaces are classified into two categories: Physical Layer-3 interfaces and logical layer-3 interfaces. logical layer-3 interfaces include layer-3 VLAN interfaces and routing sub-interfaces. layer-3 VLAN interfaces integrate the routing and bridging functions; the physical layer-3 interface has only the routing function, which is equivalent to a traditional router. 1. layer-3 logical VLAN Interface The logical layer-3 VLAN interface provides a routing

What is a vswitch port? What is the role of the vswitch port? Vswitches cannot play their role in optimizing network performance. After reading this article, you will surely have a lot of GAINS. I hope this article will teach you more. In an Ethernet Switching environment, communication between two workstations is usually not intercepted by a third party. In some cases, we may need such listeners, such as protocol analysis, traffic analysis, and intrusion detection. Therefore, we can set the SPA

The most important function of a vswitch is to speed up the fast data forwarding in a large local area network. The routing function is also used for this purpose, so the switch port issue is also very important, it is really not easy to set a vswitch port. In an Ethernet Switching environment, communication between two workstations is usually not intercepted by a third party. In some cases, we may need such listeners, such as protocol analysis, traffic analysis, and intrusion detection. Therefo

the bound hostNote:The above command sets a port on the switch to bind a specific MAC address, so that only this host can use the network, if the NIC of the host is changed or another PC wants to use the network via this port, it will not be available unless the MAC address bound to the port is deleted or modified.Note:The preceding functions are applicable to Cisco 2950, 3550, 4500, and 6500 series switches.2. solution 2-Expanded access list based o

)# Delete the MAC address of the bound host Note: The preceding command sets a port on the vswitch to bind a specific MAC address so that only the host can use the network, if the NIC of the host is changed or another PC wants to use the network via this port, it will not be available unless the MAC address bound to the port is deleted or modified. Note: The above functions are applicable to Cisco 2950, 3550, 4500, and 6500 series switches. 2. solutio

Take the Cisco 2950 vswitch as an example. log on to the vswitch and enter the management password to enter the configuration mode. Then, run the following command: Switch # config Terminal # Enter the Configuration Mode Switch (config) # interface fastethernet 0/1 # Enter the specific port configuration mode Switch (config-If) # switchport port-secruity # Configure port security mode Switch (config-If) switchport port-security Mac-address MAC (MAC address of the host) (Config-If) No switchport

) # Remove the MAC address of the binding host Attention: The above command sets a port on the switch to bind a specific MAC address. So only this host can use the network, if the host's network card has been replaced or other PCs want to use the network through this port is not available, unless you delete or modify the port binding on the MAC address to normal use. Attention: The above functions apply to Cisco 2950, 3550, 4500, 6500 series Swit

adopted by investors. Seven types of investment: 1. Common | slow growth refers to the company's income growth situation which is roughly the same as that of the overall economy. About 1%-9%. 2. Rapid growth: the company's annual revenue growth rate is above 10%. 3. Driven by specific time; it refers to the enterprise with high quality and undervalued values, preparing for complicated decomposition, financial restructuring, segmentation, or enterprise restructuring.

configuring the switch via the console port is the most common and basic management and configuration that network administrators must master. The different types of switch console ports are located in the same location, some on the front panel (such as Catalyst 3200 and Catalyst 4006), and others on the back panel (such as Catalyst 1900 and

BGP experiment, you can even use this configuration to establish full-network connectivity, and then create a tunnel port to implement the experiment topology. During remote configuration, you can save multiple configuration files and switch between them. The configuration file named router-confg can be used as a final backup-if you accidentally delete the configuration, there will still be an available configuration after the system restarts.Conclusion: The initial enchanting phenomenon is cau

Switch stack Technology 1. catlyst 1900 ------- most of them use chrysanthemum chains (I think there is no difference with cascade), but cisco thinks they are stacks: (www.2cto.com chrysanthemum chains: as the name implies, A vswitch is connected in a string (using a crossover line ). In this case, the first server must communicate with the fourth server, and must pass through two or three servers. We can imagine that data needs to be forwarded multiple times during transmission. The communicati
