2.7
Disable link flapping protection
The Huawei CE6850 switch has an inbuilt link flap protection, which by default turns off an interface if five link
flapping events occur within an interval of ten seconds. The default values might cause interfaces on certain
edge-devices to be turned off. To avoid this, change the settings for link flapping protection or disable it
completely. Refer
support.huawei.com
for further information.
To disable link flapping protection, set the threshold value to
0
.
