To configure DDR, you must complete these tasks:

1. Define what constitutes interesting traffic by using the dialer-list command.

2. Assign this interesting traffic definition to an interface using the dialer-group command.

3. Define the destination IP address, host name, telephone number to dial, and optional call parameters using the dialer map command.

4. Define call parameters using the following commands:

— dialer idle-timeout seconds: Specifies the time that the line can remain idle without receiving interesting traffic before it is disconnected. Default time is 120 seconds.

— dialer fast-idle seconds: Specifies the time that a line for which there is contention (another call is waiting to use line) can remain idle before the current call is disconnected, to allow the competing call to be placed. Default time is 20 seconds.

— dialer load-threshold load [outbound | inbound | either]: Specifies the interface load at which time the dialer initiates another call to the destination. This command is used with Bandwidth on Demand (BoD) or Multilink PPP (MLP).

Definitions of the arguments and options for the dialer load-threshold load [outbound | inbound | either command are displayed in the table.

dialer load-threshold Command




A number from 1 to 255, with 255 equal to 100 percent load and 128 equal to 50 percent load


Calculates the load on outbound data only (the default)


Calculates the load on inbound data only


Calculates the load on the maximum of the outbound or inbound data
