cannot be received by machine C, the switch should have a forwarding list (CAM). The AMC table is used to establish the correspondence between the MAC address and the port. A port can correspond to many MAC addresses, (It seems that only one can be created under 802.1x.) it seems that there is no problem. The problem is that Cam is dynamically updated in real ti
Switch Port Security Summary
The most common understanding of port security is based on the MAC address to do the control and management of network traffic, such as MAC address and specific port binding, limit the number of specific ports through the MAC address, or in the specific

Cisco switch port broadcast storm settings are more practical. When a port receives a large number of broadcast, unicast, Or multicast packets, a broadcast storm occurs. Forwarding these packets will slow down the network or cause timeout. Using broadcast storm control on ports can effectively avoid network paralysis caused by hardware damage or link failure. By

According to the current market, the switches required by ordinary small enterprises are not very expensive in terms of price, but they must also take into account the needs of various aspects, for example, if you purchase two or five vrouters that can meet the requirements of eight Connected Networks, two of them must be used as Internet access ports.) in terms of price, it is more expensive th

Introduction
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 thi

Note: Each interface supports only one policy, and one policy can be used for multiple interfaces. Therefore, the download rate limit for the network segment under the port should be defined in the same policy

We have explained a lot about the configurations of CISCO switches. Here we will mainly explain the port security configurations of CISCO 3550 switches. Scenario: There is a CISCO3550 switch in a certain unit. For the sake of network security, the security requirements for some ports are high, that is, only the specified host can be connected, for example, if you set up an office, only one laptop can access
