**Table 1** DHCP relay data model
Object	Description	Value Range	Remarks
/huawei-dhcp:dhcp-config/dhcpv4-config/enable	Indicates whether to enable the DHCP function.	The value is of the Boolean type: true: The DHCP function is enabled. false: The DHCP function is disabled. The default value is false.	N/A
/huawei-dhcp:dhcp-config/dhcpv4-config/dhcp-relay-configuration/dhcp-relays/dhcp-relay/enable	Indicates whether to enable the DHCP relay function.	The value is of the Boolean type: true: The DHCP relay function is enabled. false: The DHCP relay function is disabled. The default value is false.	N/A
/huawei-dhcp:dhcp-config/dhcpv4-config/dhcp-relay-configuration/dhcp-relays/dhcp-relay/server-ip	Indicates the IP address of the DHCP server served by the DHCP relay agent.	The value is in dotted decimal notation.	N/A
/huawei-dhcp:dhcp-config/dhcpv4-config/dhcp-relay-configuration/global-configuration/server-cycle-enable	Indicates whether the DHCP server polling function is enabled on the DHCP relay agent.	The value is of the Boolean type: true: The DHCP server polling function is enabled on the DHCP relay agent. false: The DHCP server polling function is disabled on the DHCP relay agent. The default value is false.	N/A
/huawei-dhcp:dhcp-config/dhcpv4-config/dhcp-relay-configuration/dhcp-relays/dhcp-relay/relay-information/enable	Indicates whether to enable the Option82 function on a DHCP relay agent.	The value is of the Boolean type: true: The Option82 function is enabled on the DHCP relay agent. false: The Option82 function is disabled on the DHCP relay agent. The default value is false.	N/A
/huawei-dhcp:dhcp-config/dhcpv4-config/dhcp-relay-configuration/dhcp-relays/dhcp-relay/anycast-gw-reroute-enable	Indicates whether the re-routing function for the DHCP relay agent on a distributed gateway is enabled.	The value is of the Boolean type: true: The re-routing function for the DHCP relay agent on a distributed gateway is enabled. false: The re-routing function for the DHCP relay agent on a distributed gateway is disabled. The default value is false.	N/A
/huawei-dhcp:dhcp-config/dhcpv4-config/dhcp-option82-configuration/option82-enable	Indicates whether the function of adding the Option82 field to DHCP messages is enabled. The option insertion mode on an interface or an interface in a VLAN and in a VLAN or a BD can be set to the Insert mode (insert-enable) or Rebuild mode (rebuild-enable).	The value is of the Boolean type: true: The function of adding the Option82 field to DHCP messages is enabled. false: The function of adding the Option82 field to DHCP messages is disabled. The default value is false.	N/A
/huawei-dhcp:dhcp-config/dhcpv4-config/dhcp-option82-configuration/sub-option-enable	Indicates whether the function of adding a sub-option to the Option82 field is enabled. Sub-option 1 (circuit-id-enable), sub-option 2 (remote-id-enable), suboption 6 (subscriber-id-enable), and suboption 9 (vendor-specific-enable) can be added to the Option82 field globally, on an interface, or in a VLAN or BD. NOTE: The four suboptions cannot be inserted simultaneously.	The value is of the Boolean type: true: The function of adding a suboption to the Option82 field is enabled. false: The function of adding a suboption to the Option82 field is disabled. The default value is false.	N/A
/huawei-dhcp:dhcp-config/dhcpv4-config/dhcp-option82-configuration/option82-format/vendor-specific-format/global/vendor-sub-option/option-format	Indicates the format of suboption 9 in the Option82 field. The value can be: ip-address: IP address format ascii-string: ASCII character string sysname: device name hex-string: hexadecimal character string	ip-address: The value is in dotted decimal notation. ascii-string: The value is an ASCII character string and must be smaller than 129 characters. sysname: – hex-string: The value is a hexadecimal character string. The value can contain only digits 0 to 9, uppercase letters A to F, and lowercase letters a to f. Excluding the space, the value length must be an even number smaller than 257.	N/A
