The time of backup interface activation and deactivation is both 5 seconds. Flux equalization setting is when
true flux of primary interface pass 60% of band width , activate backup interface, while flux through both
interfaces is less than 30% of band width of primary interface, activate backup interface.

backup interface int s1/1
backup delay 5 5
backup load 70 30
It is enabled when the primary interface is “down”, while the dialing backup interface is always connected.
If the backup interface is a normal dialing interface, when the primary interface is down and the backup
interface does not need to send data, the backup interface will not dial initiative, only dial when sending
data .After enabled this ,regardless of transporting data, when primary interface is “down”, backup interface
will dial at once to connect.(if you take slow dial interface as backup interface ,it is fit).
Enabled flux equlization backup, you must execute tasks as follows:
 Choose backup interface
 enabled backup interface dial at once when primary interface is “down”.
1. Choose backup interface. You can use instructions as follows in interface configuration mode.
Command Purpose
backup interface slot/port Choose backup interface of this
interface .
2. Enabled backup interface dial at once when primary interface is “down”.
You can use instructions as follows in interface configuration mode.
Command Purpose
backup always When primary interface is down, backup
Interface is always connected.
For an example(a0/0 as a dial interface)
configure router
interface s1/0
backup interface a0/0
backup always
