Configuring Error Packets Diffusion Restraint; Displaying And Maintaining Ce1 Interfaces - HP HSR6800 Configuration Manual

Step
18. Enter the view of the
synchronous serial interface
created on the CE1 interface.
19. Set the CRC mode.

Configuring error packets diffusion restraint

Error packets diffusion occurs when the error packet received on one timeslot spreads to other timeslots.
You can suppress error packet diffusion by configuring three parameters: detection period (detect-timer),
renew-timer (renew-timer), and PER threshold (threshold).
If the packet error rate for the detection period exceeds the PER threshold, the interface automatically
shuts down to avoid the risk of error packets diffusion. At the same time, the renew timer starts. When the
timer expires, the interface automatically comes up.
To configure error packets diffusion restraint:
Step
1. Enter system view.
2. Enable error packets diffusion
restraint.
3. Configure error packets
diffusion restraint parameters.
