Configuring a Dialed Backup Line Chapter 8
Configuring Dialer Services
XSR(config)#interface serial 1/0
XSR(config-if<S1/0)#dialer pool-member 6
XSR(config-if<S1/0)#no shutdown
Configure primary serial port to have interface dialer1 as its backup interface:
XSR(config)#interface serial 1/1
XSR(config-if<S1/1)#backup interface dialer1
XSR(config-if<S1/1)#backup delay 5 10
XSR(config-if<S1/1)#backup time-range 10:00 22:55
XSR(config-if<S1/1)#no shutdown
The backup time-range command specifies the time the backup dial line
should be up. In the above example the parameters are 10:00 and 22:55,
meaning that at 10:00 the backup line should be activated and at 22:55 the
backup line should be deactivated. Enabling and disabling the backup
interface takes place regardless of the traffic on the link when using the
backup time-range command.
Sample Configuration
Figure 25 shows an example of two dialer interfaces used to back up two
separate serial lines using only one dial out line (serial interface 1).
