6.3 Configuring Link State
Tracking
With Link State Tracking, when upstream links have failed, the downstream devices
can be advertised to switch over the link. By configuring upstream ports and
downstream ports of link state tracking group, Link State Tracking binds the link state
of multiple downstream ports to multiple upstream ports. When all upstream links in the
tracking group have failed, the downstream ports will be shut down, so that the packet
transmission over upstream link can be switched from primary link to the backup link.
