Table 17 Description on DLDP neighbor states DLDP neighbor state Description Unknown A neighbor is in this state when it is just detected and is being probed. A neighbor is in this state only when it is being probed. It transits to Two way state or Unidirectional state after the probe operation finishes. Two way A neighbor is in this state after it receives response from its peer. This state indicates the link is a two-way link. Unidirectional A neighbor is in this state when the link connecting it is detected to be a unidirectional link. After a device transits to this state, the corresponding neighbor entries maintained on other devices are removed. DLDP configuration task list For DLDP to work properly, enable DLDP on both sides and make sure these settings are consistent: the interval to send Advertisement packets, DLDP authentication mode, and password. DLDP does not process any link aggregation control protocol (LACP) events. The links in an aggregation are treated as individual links in DLDP. Make sure the DLDP version running on devices on the two ends are the same. Complete the following tasks to configure DLDP: Task Configuring the duplex mode and speed of an Ethernet interface Enabling DLDP Setting DLDP mode Setting the interval to send advertisement packets Setting the delaydown timer Setting the port shutdown mode Configuring DLDP authentication Resetting DLDP state Remarks Required Required Optional Optional Optional Optional Optional Optional Configuring the duplex mode and speed of an Ethernet interface To make sure that DLDP works properly on a link, you must configure the full duplex mode for the ports at two ends of the link, and configure a speed for the two ports, rather than letting them negotiate a speed. For more information about the duplex and speed commands, see Layer 2-LAN Switching Command Reference. 35
