Example
Run the display smart-link group { all | group-id } command. If lock is displayed, it indicates
that data flows are locked on the master interface. If force is displayed, it means that data flows
are locked on the slave interface.

2.4 Configuring a Monitor Link Group

This section describes how to create a Monitor Link group, configure the uplink and downlink
interfaces, and enable the revertive switching.

2.4.1 Establishing the Configuration Task

Applicable Environment
As shown in
Switch C, link switching is not performed because the active link is not faulty. In this case,
services are interrupted. To enable the Smart Link group to respond more quickly to the faults
of the uplink, you need to configure the Monitor Link function on the device connected to the
active link to monitor the status of the uplink. When a fault occurs on an uplink, the active link
of the Smart Link group is rapidly blocked. In this way, the Smart Link group can detect the
fault and switch the traffic to the standby link to reduce the service interruption duration.
When the uplink interface belongs to a Smart Link group, the uplink interface is considered as
faulty only if the maser and slave interfaces of the Smart Link group are in standby state
(including the Down state).
