How to Configure the Uplink and Downlink Interfaces in a Monitor Link Group on Huawei S5700?

Questions:

How to configure OPFA the Uplink and Downlink Interfaces in a Monitor Link Group on Huawei Quidway S5700?

Answer:

Run:system-view,The system view is displayed.
Run:monitor-link group group-id,The Monitor Link group view is displayed. The S5700 supports a maximum of 16 Monitor Link groups.
Run:port interface-type interface-number { downlink [ downlink-id ] | uplink },An interface is configured as the uplink interface or downlink interface of the Monitor Link group.
run:smart-link group group-id uplink,An interface cannot be added to a Monitor Link group in the following situations:
The interface is added to an Eth-Trunk.
The interface is added to a Smart Link group.
The interface is added to another Monitor Link group.
A Smart Link group is configured as the uplink interface of the Monitor Link group.

NOTE:
The status of the uplink interface determines the status of the Monitor Link group. Therefore, after the downlink interface is added to the Monitor Link group, the result of the shutdown or undo shutdown command can be retained before the status of the uplink interface changes. When the status of the uplink interface changes, the status of the downlink interfaces changes as follows:
When an uplink interface in Up state is added to the Monitor Link group or when an uplink interface in Down state becomes Up, all the downlink interfaces in the Monitor Link group become Up.
When an uplink interface is deleted from the Monitor Link group or when an uplink interface in Up state becomes Down, all the downlink interfaces in the Monitor Link group become Down.
To add a Smart Link group to a Monitor Link group, you need to delete the existing uplink interface of the Monitor Link group. The Smart Link group and common interfaces are incompatible when serving as the uplink interface for a Monitor Link group.
