The lldpadm command is used to enable or disable a Link Layer Discovery Protocol (LLDP) agent on a physical datalink. lldpadm is also used to configure the behavior of an LLDP agent. The LLDP agent implements the LLDP protocol for a given physical datalink. LLDP is a one-way link layer protocol that allows an IEEE 802 LAN station to advertise the capabilities and current status of the system to other stations attached to the same LAN. The LLDP agent can also receive information about the capabilities and current status of the system associated with a remote station. LLDP agent can either be enabled for transmission only, for reception only, or for both.
Information to be exchanged is packed as a sequence of type, length, and value (TLVs), wherein the type field identifies the type of information, the length field indicates the length of the information field in octets, and the value field contains the information itself.
Each lldpadm subcommand operates on one of the following objects:
An LLDP agent implements the LLDP protocol for a given physical datalink that is connected to IEEE 802 LAN. The only supported physical links are the ones of media type Ethernet. Thus, LLDP can be enabled on all the links displayed in dladm show-phys output that are of media type Ethernet. The name of the lldp_agent is the name of the datalink itself.
Name of the TLV whose value can be modified. The supported modifiable TLVs are:
syscapab and mgmtaddr. These form Global TLVs that are common to all the LLDP agents on the system.
pfc, ets, and appln. Per-LLDP agent TLVs.
lldpadm supports the following subcommands.
Sets the value of one or more LLDP agent properties to the value specified. If the property takes multiple values then the value should be specified with a comma as the delimiter. The value is always made persistent and thus will be reapplied on system reboot or lldpd(1M) daemon restart. The list of properties supported and each property's possible values can be retrieved using show-agentprop subcommand.
A comma-separated list of properties to be set to the specified values. It also provides the following qualifiers to perform add and delete operations in addition to assignment.
Adds the given value to the current list of value(s).
Removes the given value from the current list of value(s).
Makes a new assignment and removes all the current value(s).
See EXAMPLES for more information on how to use the qualifiers.
Resets one or more properties to their default values. The default values for properties can be retrieved using show-agentprop subcommand.
A comma-separated list of properties to reset.
Show the current value of one or more properties, either for all of the LLDP agents or for the specified LLDP agent. Several properties of interest can be retrieved at a time by providing comma-separated property names to -p option. If the -p option is not specified, all available properties are displayed.
A case-insensitive, comma-separated list of output fields to display. The field name must be one of the fields listed below, or the special value all to display all fields. For each LLDP agent, the following fields can be displayed:
The name of the LLDP agent.
The name of the property.
The read/write permissions of the property. The value shown will be r (read only), w (write only) or rw (read/write).
The current value of the property. If the value is not set, it is shown as --. If it is unknown, the value is shown as ?.
The default value of the property. If the property has no default value, -- is shown.
A comma-separated list of the values the property can have. If the values span a numeric range, min - max might be shown as shorthand. If the possible values are unknown or unbounded, -- is shown.
Display using a stable machine-parsable format. The -o option is required with this option. See “Parsable Output Format”, below.
A comma-separated list of properties to display.
For the supported list of agent properties, see “Agent Properties” section below.
Sets the value of one or more TLV properties to the value specified. If the property takes multiple values, the value should be specified with a comma as the delimiter. The value is always persisted and will be reapplied on system reboot or lldpd(1M) daemon restart. The list of properties supported and each property's possible values can be retrieved using show-tlvprop subcommand.
注 - The TLVs modified using this subcommand apply to all the LLDP agents running on the system.
See the description of this option under the set-agentprop subcommand, above.
Resets one or more properties to their default values. The default values for properties can be retrieved using show-tlvprop subcommand.
A comma-separated list of properties to reset.
Show the current value of one or more properties, either for all the TLVs or for a specified TLV. Several properties of interest can be retrieved at a time by providing comma-separated property names to -p option. If the -p option is not specified, all available properties are displayed.

A comma-separated list of properties to display.
Sets the value of one or more TLV properties to the value specified. The -a option is mandatory and identifies the name of the agent for which the TLV property needs to be set. In this way, the TLV property modification is reflected only on the specified agent. If the property takes multiple values then the value should be specified with a comma as the delimiter. The value is always made persistent and will be reapplied on system reboot or lldpd(1M) daemon restart. The list of properties supported and each property's possible values can be retrieved using show-agenttlvprop subcommand.
See the description of this option under the set-agentprop subcommand, above.

Show the statistics for the specified LLDP agents or for all the LLDP agents on the system. Every LLDP agent maintains statistical counters that are used to count significant events in the transmit and receive state machines. These counters are defined to be 32-bit unsigned integers.
A case-insensitive, comma-separated list of output fields to display. The field name must be one of the fields listed below, or the special value all to display all fields. For each TLV, the following fields can be displayed:
The name of the LLDP agent.
Count of all LLDP frames received by AGENT.
Count of all LLDPDUs received with one or more detectable errors.
Count of all LLDPDUs received and then discarded for any of the following reasons:

insufficient space to store the incoming LLDPDU
Count of all LLDP frames transmitted by AGENT.
Count of times the outgoing LLDPDU exceeded the length restrictions of 1500 bytes.
Count of all TLVs received and then discarded because the TLVs did not adhere to the TLV usage rules as specified by the standard.
Count of all TLVs received that are not recognized by the LLDP agent.
Count of the times that a neighbor's information has been deleted because of aging.
Displays detailed information.
The lldpadm show subcommands have a -c option that displays output in a machine-parsable format. The output format is one or more lines of colon (:)-delimited fields. The fields displayed are specific to the subcommand used and are listed under the entry for the -o option for a given subcommand. Output includes only those fields requested by means of the --o option, in the order requested. Note that the -o all option, which displays all the fields for a given subcommand, cannot be used with the parsable output option.
When you request multiple fields, any literal colon characters are escaped by a backslash (\) before being output. Similarly, literal backslash characters are also escaped with a backslash. This escape format is parsable by using shell read(1) functions with the environment variable set as IFS=: Note that escaping is not done when you request only a single field.
The following LLDP agent properties are supported:
Configures the operation mode of the LLDP agent. Possible values are:
Enables LLDP for transmission only.
Enables LLDP for receiving only.
Enables LLDP for both transmission and receiving.
Disables LLDP on the LLDP agent.
Every LLDP packet (LLDPDU) transmitted by an LLDP agent contains multiple TLVs. The following four TLVs are mandatory and therefore included in all the LLDPDUs transmitted by an agent configured in the txonly or both mode:
The value transmitted in the Chassis ID TLV is:
subtype = 7 (locally assigned)
Chassis ID = hostid(1)
The value transmitted in the Port ID TLV is:
subtype = 3 (MAC address)
Port ID = primary MAC address of the agent
The duration for which this packet is valid. The default value is 30 seconds.
End of PDU indicator.
Optional TLVs that can be advertised are configured using the following properties:

Configures the Application Priority Table for an Application TLV. One can add or remove entries from this table using the + and - qualifiers. Each entry in the table indicates the application and the priority that will be used for that application. Its value is of the form:
id/selector/priority
The meaning of the id is determined by the selector field. The selector field can be any one of the following:
1 — id indicates an Ethertype (an L2 protocol), therefore id's value should be greater than 1536
2 — id indicates a port number over TCP or SCTP
3 — id indicates a port number over UDP or DCCP
4 — id indicates a port number over TCP, SCTP, UDP, or DCCP
The priority indicates the priority value (0-7) that will be used for given application.
This property can have the following value:
Indicates whether the host is willing to accept the peer's ETS recommendation. This property is likely to change in the future.
