Configuring an Associated Device
The active and standby links in a smart link group may traverse multiple devices between the Smart
Link device and the destination device. For Smart Link to work, you need to enable all the ports on the
way to the destination to process the flush messages sent from the smart link device.
For example, as all the numbered ports on Device A, B, and D in
Figure 1-1 are on the way of the active
and standby links from Device C and E to Device A, you need to enable the ports to process flush
messages received from the control VLAN configured on Device C and E.
