recovery track

Use recovery track to associate a cellular interface with a track entry and configure auto-recovery
parameters of the 3G modem.
Use undo recovery track to remove the association.
Syntax
recovery track track-entry-number delay delay-time consecutive times
undo recovery track
Default
A cellular interface is not associated with a track entry.
Views
Cellular interface view, cellular Ethernet interface view
Default command level
2: System level
Parameters
track-entry-number: Specifies a track entry ID in the range of 1 to 1024.
delay delay-time: Specifies the delay time a 3G/4G modem waits for a positive event from the track
module. The delay timer starts when the 3G/4G modem starts auto-recovery. The value range is 1 to
1440 minutes. If the interface does not receive a positive event before the timer expires, the 3G/4G
modem attempts to recover repeatedly until the interface receives a positive event or the maximum
number of auto-recovery attempts is reached. The delay timer must be longer than the maximum amount
of time required for an auto-recovery plus the maximum amount of time for the detection module to detect
a link recovery event and report the positive event.
consecutive times: Specifies the maximum number of auto-recovery attempts for the 3G/4G modem. The
value range is 0 to 10. A value of 0 places no limit on auto-recovery attempts. When the interface
receives a positive event, the system clears this counter.
Usage guidelines
With this function, the system determines whether a cellular interface has received a positive event after
the interface receives a negative event.
• If yes, the 3G/4G modem automatically recovers. If the interface receives no positive event within
the specified delay time, the 3G/4G modem recovers repeatedly.
If not, the 3G/4G modem fails possibly because of configuration errors. In this case, the system
•
performs no action.
