In addition to the dhcp snooping method, you can also directly disable the mac address! The MAC address of machine A is 00-01-02-03-04-05, which is connected to port F0/3 of Switch B, port F0/3 is in VLAN3. Currently, forwarding of A is blocked on port B. You can set the following accord
message are correctIf a large number of messages are sent, the network bandwidth will be exhausted to form another Denial-of-Service attack.3. The client can specify the IP address at will.The client does not have to use the DHCP service. It can set IP addresses in a static way. If any,This will greatly increase the possibility of network IP address conflict.II. Introduction to DHCP Snooping TechnologyDHCP Snooping is a DHCP security feature. Cisco s
After using the Console port to set IP address information for the switch and enable the HTTP service, you can access the switch through a Web browser that supports JAVA, you can modify the parameters of a vswitch through a Web browser and manage the vswitch. In fact, you can modify and set many important parameters of a vswitch on the Web interface, and view the running status of the vswitch in real time.
