Smart Link Device Configuration Example
Network requirements
z
Create smart link group 1.
z
The protected VLANs of smart link group 1 are mapped to MSTI 0 through 8.
z
Configure GigabitEthernet 2/0/1 as the master port of the smart link group, and GigabitEthernet
2/0/2 as the slave port.
z
Configure VLAN 20 for flush update.
z
Configure the collaboration between Smart Link and the CC function of CFD on GigabitEthernet
2/0/1 and GIgabitEthernet 2/0/2.

Configuring an Associated Device
Enabling the Receiving of Flush Messages
You do not need to enable all ports on the associated devices to receive flush messages sent from the
transmit control VLAN, only those on the master and slave links between the smart link device and the
destination device.
Follow these steps to enable the receiving of flush messages:
