Link reliability can be implemented between master and backup links only after intermediate devices are enabled to receive SmartLink Flush packets so that they can transparently transmit the SmartLink Flush packets.
The system view is displayed.
A control VLAN is created and its view is displayed.
The control VLAN is used to send SmartLink Flush packets between Eth-Trunk interfaces in manual 1:1 master/backup mode. The control VLAN ID must be the same as the VLAN ID of sent SmartLink Flush packets.
Return to the system view.
The interface view is displayed. The intermediate devices' interfaces that connect to the Eth-Trunk interfaces at both ends of the Eth-Trunk link as well as the intermediate devices' interfaces that connect to each other must all be specified.
The interface is switched to Layer 2 mode.
The interface is enabled to allow packets from the control VLAN to pass through.
The VLAN ID of received and sent SmartLink Flush packets must be the same.
The interface is enabled to receive SmartLink Flush packets.
The configuration is committed.
