DLDP Configuration
1-7
z To ensure unidirectional links can be detected, you must make sure that DLDP is
enabled on both sides, and that the interval between sending advertisement
packets, authentication mode, and password are consistent on both sides.
z You can adjust the interval between sending advertisement packets in different
network circumstances so that DLDP can respond rapidly to a link failure. The
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.
z DLDP does not process any LACP event, and treats each link in the aggregation
group as independent.
z When connecting two DLDP-enabled devices, make sure the software running on
them is of the same version. Otherwise, DLDP may operate improperly.
