AMF Introduction and Configuration
New and Enhanced Features in AlliedWare Plus 5.4.4 Major and Minor Versions 145
Automatic node recovery is not intended to recover multiple nodes simultaneously. If
multiple nodes have failed, recover them one at a time.
Figure 17: Example log output showing automatic node recovery
Recovery progress indication
This is a visual feature that displays the recovery status during automatic recovery. This
feature uses two distinct flash patterns to indicate the following states:
When using this feature during a recovery failure, you can turn off the failure-alert
indication and return the port LEDs to their normal running state. To do this, use the
command “atmf recover led-off” on page 205.
You can repeat this process until the recovery failure has been fixed.
Note that the Find me and ecofriendly LED features cannot be used while AMF recovery
progress indication is active.
Restoring a Node to a “Clean” State
When replacing a failed device, your replacement device should be one of the following
types, in order for AMF automatic node recovery to work:
■ A factory-new device
■ A used device that has been returned to a “clean” state
Caution
Do not make any changes to the device's configuration while a node
recovery is underway. A log message will appear on the console or other
VTY session indicating when recovery has finished (whether successfully or
with errors). This message can also be found by viewing the log with the
show log command.
