CISCO PT Simulation Experiment (2) port configuration and management for switchesExperimental Purpose : Master the basic configuration and management of the switch, and understand the basic commands of the switch configuration.Experimental background : A company has a new batch of two-layer switch, before formally put into use to initialize the configuration and management, in order to maintain later.Technical Principle : There are two basic ways

Yesterday the company bought a few Sonos wireless hifi equipment, beans need to test the effect.As a simple test, my structure is very simple, the router (firewall) comes out to pick up the Cisco switch, then boost and my controller (computer or phone) are on a VLAN, and then between boost and player through the grid wireless network connection between themselves.Routers-Switches-SONOS boost/controller-----

How do I make a QoS-limiting configuration under the Cisco switch? How to limit BT downloads? This blog will be detailed with examples. Example 1: QoS speed limits on Cisco switches For the switch on the user's bandwidth control, the switch is usually 10/100/1000, three kinds of speed, for other rates need to carry out the speed limit of QoS, you can also limit

Q: Are there any simple tools and methods? Run the script automatically on N or so cisco switches according to the script, and then return the result?Method 1: Download and modify the vswitch configuration file and upload it to N vswitches. Restart or copy start run.Method 2: Create a bat file under windows. The content in the file is the same as the command you used to telnet to the vswitch for modificatio

configuration and monitor network conditions, you can do so either by controlling the command menu or by using the web-based Catalyst 1900 Switch manager anywhere. If the switch is running Cisco Catalyst 1900/2820 Enterprise Edition software. You can change the configuration by using the command control port (command-line interface CLI). When you enter the configuration main interface, the menu is display

When switching data frames, a switch can select different modes to meet network and user needs. Cisco switches provide three switching modes: Storage forwarding Mode The Store-and-forward mode means that the switch can complete the entire data frame and perform the forwarding operation only after the CRC verification is passed. If CRC verification fails, that is, the data frame is incorrect, the switch d
