2.3 Configuring a Flow Control Policy in a Smart Link
Group
This section describes how to configure the advanced functions of the Smart Link group, such
as lock of data flows and manual switchover between links.
2.3.1 Establishing the Configuration Task
Applicable Environment
As shown in Figure 2-2, the basic functions and revertive switching of the Smart Link group
are enabled on Switch D. During maintenance, the active link in the Smart Link group needs to
be inspected. To prevent the inspection from affecting normal services, you need to configure
a flow control policy for the Smart Link group. Through the configuration, you can forcibly lock
the data flows to the standby link and switch them back to the active link after the inspection is
complete.
