DGS-6604 m accept dhcp client-identifier accept dhcp client-identifier Use this command to turn on validation checking of the Client Identifier. Use the no form of the command to turn off validation checking of the Client Identifier. accept dhcp client-identifier no accept dhcp client-identifier Syntax None Default client identifier: not evaluated Command Mode Usage Guideline DHCP pool configuration To validate the DHCP Client Identifier value sent by the client. If a DHCP client sends a DHCP Client Identifier option, the DHCP server validates the value to ensure it matches the hardware type and client hardware address. If the values match, the DHCP server provides service to the client. If the values do not match, the DHCP server does not respond to the client's request. Example If the command is used to set the validation to not check the DHCP Client Identifier value sent by the client, then the DHCP server only checks the matching of the client's hardware type and hardware address as a host ID. The following example sets the DHCP pool1 to check the validation of the client identifier option as DHCP pool1 offers IP addresses. switch > enable switch# configure terminal switch(config)# ip dhcp pool pool1 switch(config-dhcp)# accept dhcp client-identifier switch(config-dhcp)# CLI Reference Guide 31
