Scenario

Description

Task

Configure basic functions of Smart Link

Basic functions of Smart Link can be configured to implement active/standby link redundancy and switching, improving network reliability.

Configuring Basic Functions of Smart Link

Configure load balancing in a Smart Link group

Load balancing improves link efficiency.

Configure Smart Link to notify the VPLS/VLL module of link switching events

When Smart Link is used in VPLS or VLL networking, the link switching notification function enables the VPLS/VLL module to quickly detect link switching events, which minimizes data loss.

Configure Monitor Link

Monitor Link monitors an uplink interface on a device and triggers Up/Down state transitions on downlink interfaces in accordance with state changes on the uplink interface. State transitions on the downlink interfaces then trigger link switching of the topology protocol on the downstream device.
