Configuring a Signal Sending Delay on an Interface

When an interface on the ME60 is dual-homed to non-Huawei devices, configure a signal sending delay on the interface to avoid data loss due to asynchronous link switchover or incomplete configuration restoration.

When the ME60 configured with VRRP or E-APS services is dual-homed to non-Huawei devices, the ME60 cannot control traffic switchover between interfaces on the non-Huawei devices. In this case, link switchover on the ME60 is probably asynchronous with that on the non-Huawei devices. If the interface on the ME60 sends a signal immediately after being initialized, certain data is probably lost.

If an interface on the ME60 is directly connected to a non-Huawei device, when the ME60 is restarted, the interface sends a signal to the peer immediately after being initialized, which probably causes data loss before configurations of the ME60 are restored.

To prevent the problem, configure a signal sending delay on the ME60.
