Usage guidelines
Before you can use this command on an interface, you must specify at least one backup interface for the
interface.
This command takes effect when the primary and backup interfaces operate in load sharing mode.
Interface backup compares the amount of traffic with the thresholds at this interval to determine whether
to activate or deactivate a backup interface.
Examples
# Set the traffic polling interval to 60 seconds on Serial 2/1/0.
<Sysname> system-view
[Sysname] interface serial 2/1/0
[Sysname-Serial2/1/0] backup timer flow-check 60

Usage guidelines
To change the state of a backup interface response to the link state of the primary interface, use this
command. For the setting to work, you must configure the track entry to monitor the state of the primary
link. For more information about configuring a track entry, see High Availability Configuration Guide.
You can associate an interface with only one track entry.
You can create the associated track entry before or after the association. The association takes effect after
the track entry is created.
To maintain performance, limit the number of associations to 64.
This command and the backup interface command are mutually exclusive.
• If you have configured the backup interface command on the primary interface, you cannot
configure the backup track command on the primary or backup interface.
