Monitor Link overview

Monitor Link is a port collaboration function. Monitor Link usually works together with Layer 2
topology protocols. The idea is to monitor the states of uplink ports and adapt the up/down state of
downlink ports to the up/down state of uplink ports, triggering link switchover on the downstream
device in time, as shown in
Figure 25 Monitor Link application scenario

Terminology

Monitor link group
A monitor link group is a set of uplink and downlink ports. A port can belong to only one monitor link
group. As shown in
monitor link group. Port1 on both devices are uplink ports, and Port2 on both devices are downlink
ports.
Uplink/Downlink ports
Uplink port and downlink port are two port roles in monitor link groups:
•
Uplink ports are the monitored ports. The state of a monitor link group adapts to that of its
member uplink ports. When a monitor link group contains no uplink port or when all the uplink
ports are down, the monitor link group becomes down. As long as one member uplink port is up,
the monitor link group stays up.
