**Table 1** Configuration objects of LLDP
Object	Description	Value	Remarks
/huawei-lldp:lldp/enabled	Indicates whether the global LLDP function is enabled on the switch.	The value is of the Boolean type: true: This function is enabled. false: The function is disabled. By default, the global LLDP function is enabled on the switch.	Operations can be performed on other objects only when the global LLDP function is enabled on the switch.
/huawei-lldp:lldp/sensor-ap-vlanid	Configures the switch to identify Huawei Fit APs using LLDP and adds the interfaces receiving LLDP packets from the APs to the specified VLAN in untagged mode.	The value is an integer ranging from 1 to 4094. By default, this function is disabled.	The VLAN specified in the object can be an existing VLAN or created after this object is executed, but cannot be the control VLAN of ring protocols such as SEP, RRPP, and ERPS.
/huawei-lldp:lldp/sensor-ap-trunk-vlanid	Configures a switch to automatically identify Huawei Fit APs through the LLDPDUs sent from the Fit APs and add the receiving interfaces to the specified VLAN in tagged mode.	The value of this object can be either of the following: An integer in the range from 1 to 4094. A string of characters in the format of x..y, which represents VLAN x to VLAN y. The value of x and y is an integer in the range from 1 to 4094, and the value of y must be greater than or equal to that of x.	Multiple VLAN configurations are supported. The value of this object cannot contain the VLAN IDs configured by /huawei-lldp:lldp/sensor-ap-vlanid object.
/huawei-lldp:lldp/management-address	Configures the LLDP management IP address.	The value is in dotted decimal notation.	N/A
/ietf-interfaces:interfaces/interface/huawei-lldp:lldp/admin-status	Indicates whether the LLDP function is enabled on the interface.	The value is of the enumerated type: tx-rx: The LLDP function is enabled on the interface. disabled: The LLDP function is disabled on the interface. By default, the LLDP function status on an interface is the same as the global LLDP function status.	N/A
/ietf-interfaces:interfaces/interface/huawei-lldp:lldp/compliance-cdp-status	Refer to the value.	The value is of the enumerated type: rx-only: CDP-compatible LLDP is enabled on the interface. tx-rx: The interface is enabled to exchange information with CDP-capable voice devices. disabled: The above functions are disabled. By default, the two functions are disabled.	N/A
/ietf-interfaces:interfaces/interface/huawei-lldp:lldp/tlv/med/tlvs/type	Specifies the MED TLVs advertised on the interface.	The value is tlv-med-network-policy, indicating that the Network Policy TLV is advertised on the interface. Network Policy TLV is used to exchange VLAN configurations between network devices and terminal devices. A switch uses this TLV to advertise Voice VLAN ID and voice stream priority to an IP phone. Then the IP phone forwards packets according to the received Voice VLAN ID and priority, ensuring the voice quality.	This object and /ietf-interfaces:interfaces/interface/huawei-lldp:lldp/tlv/med/tlvs/enable must be configured simultaneously.
/ietf-interfaces:interfaces/interface/huawei-lldp:lldp/tlv/med/tlvs/enable	Indicates whether the MED TLV is advertised on the interface.	The value is of the Boolean type: true: The MED TLV is advertised. false: The MED TLV is not advertised. By default, the MED TLV is not advertised on the interface.	This object and /ietf-interfaces:interfaces/interface/huawei-lldp:lldp/tlv/med/tlvs/type must be configured simultaneously.
/ietf-interfaces:interfaces/interface/huawei-lldp:lldp/tlv/med/tlvs/parameters/network-policy/vlan-type	Specifies the VLAN type in the Network Policy TLV advertised on the interface.	The value is of the enumerated type: network-policy-vlan-vlanid: The Voice VLAN ID is encapsulated when Network Policy TLV is advertised. network-policy-vlan-8021: The VLAN ID of the Voice VLAN is set to 0. network-policy-vlan-untagged: Terminals are configured to send untagged voice packets.	If this object is configured as network-policy-vlan-vlanid, you must configure the /ietf-interfaces:interfaces/interface/huawei-lldp:lldp/tlv/med/tlvs/parameters/network-policy/parameters/vlanid object simultaneously.
/ietf-interfaces:interfaces/interface/huawei-lldp:lldp/tlv/med/tlvs/parameters/network-policy/parameters/vlanid	Specifies the Voice VLAN ID.	The value is an integer ranging from 1 to 4094.	This object can be and must be configured only when the value of /ietf-interfaces:interfaces/interface/huawei-lldp:lldp/tlv/med/tlvs/parameters/network-policy/vlan-type is network-policy-vlan-vlanid.
/ietf-interfaces:interfaces/interface/huawei-lldp:lldp/tlv/med/tlvs/parameters/network-policy/parameters/cos	Specifies the 802.1p priority of the voice packets.	The value is an integer ranging from 0 to 7, and the default value is 5. A larger value indicates a higher priority.	This object can be configured only when the value of /ietf-interfaces:interfaces/interface/huawei-lldp:lldp/tlv/med/tlvs/parameters/network-policy/vlan-type is network-policy-vlan-vlanid or network-policy-vlan-8021.
/ietf-interfaces:interfaces/interface/huawei-lldp:lldp/tlv/med/tlvs/parameters/network-policy/parameters/dscp	Specifies the DSCP priority of the voice packets.	The value is an integer ranging from 0 to 63, and the default value is 46. A larger value indicates a higher priority.	This object can be configured only when the value of /ietf-interfaces:interfaces/interface/huawei-lldp:lldp/tlv/med/tlvs/parameters/network-policy/vlan-type is network-policy-vlan-vlanid or network-policy-vlan-8021.
/huawei-device:device/domain-name	Adds a suffix to a device name.	The value is a string of 1 to 255 characters without spaces. Letters, digits, hyphen (-), underscores (_), and dots (.) are allowed.	Only the S2720-EI, S5720-LI, S5735-L, S5735S-L, S5735S-L-M, S5720S-LI, S5720-SI, S5735-S, S5735S-S, S5735-S-I, S5720S-SI, S5720I-SI, S5730-SI, S5730S-EI, S6720-LI, S6720S-LI, S6720-SI, and S6720S-SI support this object.
/huawei-device:device-state/domain-name	Queries the suffix of a device name.	The value is a character string.	This object only supports the get operation.
