Dell EMC recommended switch configuration
9 Huawei CloudEngine 6850 Switch Configuration Guide for Dell EMC SC Series SANs | SCG3464
2.11 Calibrate link flapping protection setting (optional)
Huawei CE 6850 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.
Section 2.7 shows the commands to disable link flapping protection, or if choosing to keep the link flapping
protection turned on, use the following steps to calibrate the link flapping protection setting. Refer to
support.huawei.com for further information.
<HUAWEI> system-view
Enter system view, return user view with return command.

[*HUAWEI-port-group] port link-flap threshold <5 to 10>
[*HUAWEI-port-group] quit
With port link flapping protection enabled, use the following command for auto recovery of an interface which
was brought down due to link flap.
