Each TLV unit has properties that you can further configure with specific values. If the TLV unit is enabled as an LLDP agent's property, then that TLV unit is advertised in the network only with the specified values. For example, consider the TLV unit syscapab, which advertises a system's capabilities. These capabilities can potentially include support for routers, bridges, repeaters, telephones, and other devices. However, you can set syscapab so that only those capabilities that are actually supported on your specific system, such as routers and bridges, are advertised.
The procedure for configuring TLV units depends on whether you are configuring global TLV units or per-agent TLV units. For information about how to configure TLV units, see Specifying TLV Units and Values for the LLDP Packet of an Agent.
Global TLV units apply to all LLDP agents on the system. The following table lists the global TLV units and their corresponding possible configurations.
TLV units that are specific to LLDP agent are managed on a per-agent basis. With per-agent TLV units, the values that you provide are used when the TLV unit is enabled for transmission by a specific LLDP agent.
The following table lists the TLV values and their corresponding possible configurations for an LLDP agent.
