(Optional) Setting the Interval for Sending LDT Packets

(Optional) Setting the Interval for Sending LDT Packets


An LDT-enabled interface sends LDT packets at intervals. A shorter interval indicates that the system sends more LDT packets in a given period and detects loops more accurately. However, more system resources are consumed and system performance is affected. You can adjust the interval for sending LDT packets according to actual networking to balance system performance and LDT accuracy.


  1. Run system-view

    The system view is displayed.

  2. Run loop-detection interval-time interval-time

    The interval for sending LDT packets is set.

    By default, the interval for sending LDT packets is 5s.
