unidirection detect information:

bidirection detect information :
action : warnning
state : normal
loop detect information :
action : block
state : normal
Several precautions in configuring port detection:
z The routing interface does not support the shutdown-svi error handling
method, so this method is not executed in case of the occurring of
detection error.
z In configuring loop detection, the neighbor devices downward connected
with the port cannot enable the RLDP detection; otherwise, the port cannot
have correct detection.
z If the block method is configured on the aggregated port and the link
detection error happens, do not change the member port relations of the
aggregate port before the port reset detection; otherwise, the forwarding
status of the member interface may have unexpected effects of forwarding
status.
z If the RLDP detects link error, alarm information will be given. The user can
send the alarm information to the log server by configuring the log function.
At least 3 levels of log shall be ensured.
z You are recommended to specify the diagnosis type of the loop detection to
shutdown-port for the reason that for some devices, even if the device
detects the loop and specifies the block port, a large amount of packets will
be sent to the CPU for the hardware chip limitation.
7.2.4 Configuring RLDP Detection
Interval
The port with the RLDP function enabled will send the RLDP Probe messages
on a regular basis.
In the global configuration mode, follow these steps to configure the RERP
detection interval:
