Layer-3 Switch for Cisco switches Although single-arm routing solves the communication problem between different VLANs, it also has its fatal defects: -The single arm itself is the Backbone link of the network, which is easy to form a network bottleneck. -The sub-interface relies on physical interfaces, and the application is not flexible -You need to view the route table for each vlan forwarding, wasting

listening Switch # show ip dhcp snooping Iv. IPSG (IP Source Protection) Ip source guard forms an ip source binding table based on the dhcp snooping function and only works on Layer 2 ports. IPSG provides a detection mechanism to ensure that the packets received by a single interface can be received by each interface. If the check succeeds, the data packet is licensed; otherwise, the activity against the policy will occur. IPSG not only ensures that

In the middle of a Cisco switching network, how do I find out which port of the switch is connected to the IP address of a machine? The most convenient and quick way is to use the User tracking function of the CiscoWorks 2000 LMS network management software. The graphical interface is clear at a glance. If you do not have this software, you can use the following

With the development of China's routing industry, we have also promoted the update and upgrade of the routing switch technology. Here we have introduced the IOS restoration method of the Cisco routing switch, and we have tried one method, after Flash is deleted, the system cannot be started. You can use X-Modem to restore it. At that time, I accidentally deleted
