Configuring error packets diffusion restraint
Error packets diffusion refers to the situation when one timeslot receives a certain error packet, all the
other timeslots are affected and also receive error packets.
You can restrain error packet diffusion by configuring three parameters: detect-timer, renew-timer, and
threshold, which function in the following way:
If, during the time specified by detect-timer, the ratio of error packets on an interface is greater than that
specified by threshold, the interface is regarded as faulty and is shut down. After waiting for some time
specified by renew-timer, the interface is brought up again.
To configure error packets diffusion restraint:

Optional.
By default, the values are 30
seconds for detect-timer, 600
seconds for renew-timer and 20%
for the threshold.
4. Restart the channel that is shut
down for the sake of error
