DLDP Configuration Commands
1-5
Parameters
Integer: Interval of sending DLDP packets, in the range of 1 seconds to 100 seconds. It
is 5 seconds by default.
Description
Use the dldp interval command to set the interval of sending advertisement packets
when all the DLDP-enabled ports are in the Advertisement status.
Use the undo dldp interval command to restore the interval to the default value 5
seconds.
By default, the interval of sending advertisement packets is 5 seconds.
Note that:
z The interval you define is applicable to all DLDP-enabled ports.
z The interval must be shorter than one-third of the STP convergence time. 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. Generally, the STP convergence time is
30 seconds.
z For the dldp interval integer command, make sure that the same interval for
transmitting advertisement packets is set on the ports used to connected both
devices; otherwise DLDP will not operate properly.
Examples
# Set the interval of sending advertisement packets to 20 seconds for all the
DLDP-enabled ports.
