1.7 Precautions for DDR Configuration
1.7.1 Configuring Dialer-group
Dialer-group must be configured at the logic dial interface or at the physical interface
that directly enables DDR, and dialer-group must correspond to dialer-list configured in
global configuration status, as shown in the following bold-typed parts.
Quidway(config)# dialer-list 1
protocol ip permit
Quidway(config)# dialer-list 1 protocol ipx permit
Quidway(config)# interface dialer 0
Quidway(config-if-Dialer0)# dialer in-band
Quidway(config-if-Dialer0)# dialer-group 1
1.7.2 Configuring Synchronous/Asynchronous Serial Port Using DDR
To make synchronous/asynchronous serial port visible and perform DDR configuration
on it, it is necessary to execute two configuration commands, physical-layer async and
modem, and enable DDR command, as shown in the following bold-typed parts.
