Enabling LLDP on the System

You can configure LLDP to exchange system information with other hosts or peers on the network.

The SMF property auto-enable-agents controls the way in which you can enable LLDP agents on the system. With this property, you can choose to enable LLDP globally across all the physical links or only one physical link at a time.

    The SMF property auto-enable-agents can have one of the following three possible values:

  • yes enables LLDP on all ports in the transmit and receive (both) mode provided that no previous LLDP configuration exists on a port. If a configuration exists on a port, then that port's configuration is retained. For example, if a port has been previously configured with LLDP in the rxonly mode, then the LLDP service will not switch the agent to run in the transmit and receive (both) mode. LLDP on that port continues to be in the rxonly mode. This is the default value of the SMF property auto-enable-agents.

  • force enables LLDP in the transmit and receive (both) mode on all ports and overrides any existing LLDP configurations on any port. For example, if a previous LLDP configuration on a port runs in the rxonly mode, the LLDP agent is switched to run in the transmit and receive (both) mode, which is the default LLDP mode.

  • no disables automatic enabling of LLDP on all ports except those with existing LLDP configurations. On these ports, the existing LLDP configuration is retained.

Note -  Every time you customize the auto-enable-agents property, you must restart the LLDP service for the new value to become effective.
