interval must be shorter than one-third of the STP convergence time, which is
generally 30 seconds. If too long an interval is set, an STP loop may occur before
DLDP shuts down unidirectional links. On the contrary, if too short an interval is set,
network traffic increases, and port bandwidth is reduced.

DLDP does not process any LACP event, and treats each link in the aggregation
group as independent.
