lower threshold for the active interface traffic. If this threshold is configured, load balancing mode is
adopted. Otherwise, active/standby mode is adopted.
• If a dialer interface acts as the active interface, the load balancing mode does not take effect.

Configuring interface backup
You can configure interface backup through active/standby mode or association between an interface
and a track entry, but you cannot configure them at the same time.
185BConfiguring active/standby mode
You can configure multiple standby interfaces for one active interface. The standby interfaces are
activated depending on their priority, with the highest priority being activated first.
To prevent frequent interface switchover as a result of interface instability, you can configure a switchover
delay. A standby interface then takes over only if the active interface remains down upon expiration of
the delay.
Follow these guidelines when you configure active/standby mode:
• To configure multiple standby interfaces for an active interface, execute the standby interface
command multiple times.
• You can use the ip route-static command in system view to configure the routes for reaching a
destination network through the active interface and its standby interfaces. For more information
about the command, see Network Management Command Reference.
• If multiple standby interfaces have the same priority, when the active interface is down, the standby
interface configured first is selected.
