DGS-6604 based-on client-id based-on client-id This command is used to specify the client identifier as a rule for IP address assignment from the DHCP address pool. Use the no form to remove the rule from DHCP address pool. based-on client -id {hex|string} CLIENT-ID no based-on client -id {hex|string} CLIENT-ID Syntax Description CLIENT-ID A sequence of bytes or a string defined on the client that is an unique identification of client. HEXADECIMAL: The maximum length is 128 bytes. STRING: The maximum length is up to 64 bytes. Default Command Mode Usage Guideline Examples None DHCP pool configuration All rules take effect on the corresponding DHCP address pool and will have a logical AND operation conditions combined with other rules set by other basedon commands. If a DHCP client sends the no DHCP Client Identifier option, the service continues to operate as it bases it on the hardware type and a client hardware address. If a DHCP client sends a DHCP Client Identifier option, the DHCP server validates the value to ensure the client identifer optional field matches the configured Client Identifier. 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. Multiple based-on client-id commands create a list of client-ids for the DHCP address pool. When any request has a match in the list, the server will provide an IP address to the server based on DHCP Client Identifier option, but not the received client Hardware address.
