Usage Guidelines

Usage Scenario

Cascading of Smart Link and Monitor Link improves link backup reliability. When the uplink interface is a Smart Link group, the uplink interface is considered faulty and the Monitor Link group forcibly disables the downlink interfaces only if both the master and slave interfaces of the Smart Link group are in Inactive or Down state.

Prerequisites

A Smart Link group has been created using the smart-link group command.

Precautions

A Smart Link group can be added to only one Monitor Link group.

A Smart Link can function only as the uplink interface in a Monitor Link group.

When the uplink interface fails, all the downlink interfaces in the Monitor Link group are shut down.

Before adding a Smart Link group to a Monitor Link group, delete the previous uplink interface from the Monitor Link group.

Example

# Add Smart Link group 1 to Monitor Link group 2 as the uplink interface.

<HUAWEI> system-view
[HUAWEI] monitor-link group 2
[HUAWEI-mtlk-group2] smart-link group 1 uplink
