DDR Configuration
1-11
In a Dialer Rotary Group, when the traffic bandwidth of a physical interface exceeds the
preset threshold, DDR will start another physical interface and transfer data to the
same destination.
Perform the following task in the dialer interface configuration mode.
Table DC-1-19 Set load threshold
Operation Command
Set load threshold dialer load-threshold load [ either | inbound | outbound ]
Configure the interface encapsulated with PPP to
operate in MP mode
ppp multilink
9) Set autodial interval
The following command, used in combination with the key word autodial in dialer map
command, is used to set the interval for DDR to make autodial attempts.
Please use the following command in the configuration mode of the dial interface.
Table DC-1-20 Set autodial interval
Operation Command
Set autodial interval dialer autodial-interval seconds
The default interval is 300 seconds.
1.4.2 Configuring Dialer Profile
I. Introduction to Dialer Profile
Dialer Profile allows the configuration of a physical interface and the logic configuration
of a call to be made separately, and then dynamically bind the two to place a call.
Dialer Profile uses Dialer Profiles to describe its dial attributes. All calls to the same
destination network use the same Dialer Profiles. A Dialer Profiles include the following
elements:
z
A logic dial interface, corresponding to a dial string, used to reach a destination
network.
z
Features of the dial interface, such as idle-timeout.
z A Dialer Pool, the set of bound physical interfaces with priorities, used for dial.
In a Dialer Profiles, the relation between dial interfaces, Dialer Pool and physical
interfaces is:
z
One dial interface can use only one Dialer Pool.
z One Dialer Pool may contain several physical interfaces with different priorities,
and a physical interface may belong to several different Dialer Pool.
Therefore, in configuring DDR with Dialer Profile, the configuration tasks for a physical
interface include: select encapsulation, configure Dialer Pool to which the interface
belongs, and set dial authentication mode.
The relation between dial interfaces, Dialer Pool and physical interfaces is shown in the
following diagram.
