Usage Scenario
A Smart Link group takes effect and blocks the slave interface only after it is enabled. After the Smart Link group is disabled, the slave interface is unblocked.
After creating a Smart Link group and adding interfaces to the group, you must enable the Smart Link group to make it effective.
Precautions
After a Smart Link group is enabled, the slave interface is blocked only if the master and slave interfaces are both in Up state.
