1.5 Monitoring and Maintenance of DDR

In any configuration mode, the following command can be used to display dial interface information, thus monitoring and maintaining DDR.

Operation	Command
Display dial interface information	show dialer [interface interface-type interface-number]

For example:

Quidway# show dialer interface serial 1

The system displays:

Serial1 - dialer type = Serial		Successes	Failures Max_call
NextHop_address	Dialer_Strings
Last_call

100.1.1.18888

Idle	timer (120 secs),	Fast Idle timer (20 secs)
Wait	for carrier (60 secs),	Re_enable (20 secs)

The above includes dialer map table at the interface and such information as the configuration of DDR features. Specific items are explained in the following table.
