First, the question of the proposed and requirements
With 802.1x identity authentication, solve the problem of Mac binding, but still can not locate the physical location of the user's computer, because the computer access in which switch on the first few ports, or do not know, the user computer change
It is very helpful to know about layer-3 switch ports. Here we mainly introduce the process of layer-3 Switch Port initialization. It may take 30 seconds or more to connect a computer to a vswitch before the computer can communicate over the network. If you are waiting for a long time, 30 seconds of waiting will make you feel very long. Let's take a look at how t

You can easily select your preferred method to implement 24 full gigabit switches. Many methods will make you suddenly enlightened. Test

The author believes that the first step requires you to open the Network Protocol analyzer and capture the data sent from the core router. From the Protocol analyzer, you can see tha
To configure a vswitch port image, experts can understand the following knowledge about the vswitch port image configuration. You only need to complete the vswitch port image configuration in a few minutes. The local connection is also mentioned in this article.

More and more cases require Port Security recently. Port security is mainly used to restrict access to port access by binding a client Mac. The ACL between VLANs is not in the current range.
After several days of practical debugging, I learned from the experiences of my predecessors and summarized my debugging experiences as follows:

What you need to know most about the H3C switch port security mode is that we often use a network technology application for network management and network device configuration. Many readers often encounter such application requirements. In fact, the most direct and simple method for user network access control is to configure port-based security mode, not only f

As the core network switch of our company, the CISCO3550 has been running stably for many years, and its functions can also meet our needs. However, its port speed limit function is not as easy to implement as some other switches, fortunately, the implementation method has been found recently. After the configuration is complete, it is verified with the iperf software. The result shows that this method is e
The most widely used switch for small and medium-sized enterprises is the 24-port Gigabit Switch. Therefore, when purchasing a switch, you must make full consideration. A clear purpose is to save costs for everyone. In network equipment, switches may be the most familiar devices of network administrators, especially ac

Generally implement VLAN communication, or use a three-tier switch, or a single arm routing, both of which are very expensive, so when there is the need for VLAN communication, and the data volume of the VLAN communication is not very large, with 50 of Soho route to build a network is very affordable.
My original demand is this:With an n-port two-layer swi

The NIC of a common PC can identify such packets for communication; the structure of the tag packet is changed after the source mac address and the target mac address, with 4-bytes vlan information added,
Performance Tests on layer-2 and layer-3 vswitches with 24 ports and all-gigabit vswitches have encountered many problems recently. Experts have said that QoS ensures port congestion, high-priority data is processed first. It makes sense to improve the utilization of 24 fully-gigabit switches with insufficient bandwidth.

When maintaining the dormitory network for a few days, I encountered a very unique problem at the time: No matter how the 20 Ports of the vswitch on the fourth floor are connected, the link cannot be connected; when the switch enters, the port cannot be enabled; there is no problem connecting to other ports. I thought it was because the port broke down. Later I h
