4.3.1.3 Link Fault Passthrough
Link Fault Pass-through
Link Fault Pass-through is a networking feature. It facilitates the detection and propagation of link faults or errors from one
network device to another. It helps maintain network reliability and minimizes downtime by allowing devices to dynamically
respond to link faults. Link Fault Pass-through improves fault detection and enables faster troubleshooting and resolution
processes.
How it works:
When a link fault occurs, the device experiencing the fault generates a notification.
This notification is then forwarded to other connected devices using Link Fault Pass-through.
Upon receiving the link fault information, the connected devices become aware of the fault.
This awareness enables them to take appropriate actions, such as rerouting traffic or disabling the affected port.
The LFP group can be made up of Copper-to-Fiber or Fiber-to-Fiber connections. These two types of groupings are shown in
Figure 4-3-7
and
4-3-8
respectively.
