On the 3560 switch, the show ip DHCP binding can see the corresponding table of IP address and MAC address broadcast through the DHCP service, for example: switch#show IP DHCP binding IP address client-id/ Lease expiration type Hardware address192.168.10.7 0100.0c76.fe36.66 Jan 11:04 am Automatic192.168.10.8 0100.1a4b.6131.15 Jan 11:04 am automatic192.168.10.9 0100.0fea.ac12.6f Jan 19 11:04 am automatic Take the first example: 192.168.10.7 is the issued IP address The corresponding MAC address is 0100.0c76.fe36.66 (the MAC address learned by the switch and can be seen to consist of 14 16 binary numbers) We do one-to-one binding: On the 3560 switch, first: 3560#config terminal3560 (config) #ip DHCP pool bundEL-1 (name can be defined by itself) 3560 (config-dhcp) #host 192.168.10.7 255.255.255.03560 (config-dhcp) #client-identifier 0100.0c76.fe36.66 (Bind 192.168.10.7 with MAC address 0100.0c76.fe36.66 one-to-one) 320gb 172.19.11.26 00-22-15- Cf-58-f2 0100.2215.CF58.F2
