Default Command Mode Usage Guideline Examples None DHCP pool configuration This command is used to create the address binding rule for the DHCP address pool. One user class is allowed in one DHCP address pool. Use the no form of the command to remove user-class rule. This command will be combined using logical AND operations with the other rules set by all the other based-on commands. For example, if the first rule is based-on user-class alpha and there is another based-on c-vid 200 command, the address pool will only assign an IP address to the client which has CVID=200 and user class as alpha. The following sets a rule used for IP address assignment based on the user class alpha from DHCP address pool1. switch(config)#ip dhcp pool pool1 switch(config-dhcp)#based-on user-class string alpha The following sets a rule used for IP address assignment based on the user class 0x8080 from DHCP address pool1. switch(config)#ip dhcp pool pool1 switch(config-dhcp)#based-on user-class hex 0x8080 CLI Reference Guide 65
