Therefore, before enablingDLDP, make sure that optical fibers or copper twisted pairs are connected.z To ensure unidirectional links can be detected, make sure DLDP is enabled on both sides; and theinterval for sending advertisement packets, authentication mode, and password are the same onboth sides.z The interval for sending advertisement packets ranges from 1 to 100 seconds and defaults to 5seconds. You can adjust this setting as needed to enable DLDP to respond in time to link failures.If the interval is too long, STP loops may occur before unidirectional links are terminated; if theinterval is too short, network traffic may increase in vain and available bandwidth decreases.Normally, the interval is shorter than one-third of the STP convergence time, which is generally 30seconds.z DLDP does not process any link aggregation control protocol (LACP) event, and treats each link inthe aggregation group as independent.
