Monitor Link Configuration Example

Network requirements
As shown in Figure
Device C is dually uplinked to Device A through a smart link group.
It is required that when GigabitEthernet 2/0/1 or GigabitEthernet 2/0/2 of Device A fails, Device C
can sense the link failure and perform link switchover in the smart link group.
For detailed information about smart link, refer to Smart Link Configuration in the High Availability
Volume.
