Comprehensive example of configuring layer-3 Switching This configuration has no problems. As long as you can understand and remember the key commands, I believe you have a deeper understanding of Layer 3. **************************************** ************************ Basic Network Conditions The network topology is as follows: the center switch uses Cisco Catalyst 4006-S3, Supervisor Engine iii g Engine is located in 1st slots for layer-3 switching; one 24-Port The 1000Base-T module is l

This is often the case of 100,000 in a rush. However, the more urgent the system is, the more difficult it is to create a command than to log on to the system, because some system prompts will pop up from time to time (or continuously) on the configuration interface opened by the Super Terminal.

In the switched Ethernet environment, the communication between the two workstations is not heard by the third party. In some cases, we may need to do such listening, such as protocol analysis, traffic analysis, intrusion detection. For this we can set the span (switchedportanalyzer Switch Port Analyzer) feature of the Cisco switch, or the early "port mirroring", "Monitoring port" feature. The object that the listens to can be one or more Ethernet switch ports, or the entire VLAN. If the port

While Windows8 is still in pre-release versions, major software vendors and online service providers are gearing up for development and testing to prepare for WINDOWS 8 compliant programs.

With the official listing of WIN8, the compatibility of WIN8 with Web sites and software is commendable, thanks to the cooperation and efforts of various software providers. For the da

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
