Configuring a Dialed Backup Line

Configuring the Interface as the Backup Dialer Interface

1. Enter interface serial card/port to specify the interface to back up.
2. Enter ip address ip-address mask to specify the IP address and subnet mask of the interface.
3. Enter backup interface dialer number as the backup interface.
4. Enter backup delay enable-delay disable-delay to set the interval between the physical interface
going down and the backup being enabled, and between the physical interface coming back
up and the backup being disabled.
5. Enter backup time-range start-time end-time to set the time of day the backup interface should

The CLI commands shown below configure the example shown in
Configure interface dialer 0 to use dial pool 5:
XSR(config)#interface dialer 0
XSR(config-if<D1>)#encapsulation ppp
XSR(config-if<D1>)#dialer pool 5
XSR(config-if<D1>)#no shutdown
Configure interface dialer 1 to use dial pool 5:
XSR(config)#interface dialer 1
XSR(config-if<D1>)#encapsulation ppp
XSR(config-if<D1>)#ppp authentication chap pap
XSR(config-if<D1>)#dialer pool 5
XSR(config-if<D1>)#no shutdown
Configure serial port(s) for dial purposes and assign to dial pool 5:
XSR(config)#interface serial 1/2
XSR(config-if<S1/2>)#encapsulation ppp
XSR(config-if<S1/2>)#media-type v35
XSR(config-if<S1/2>)#dialer pool-member 5
XSR(config-if<S1/2>)#no shutdown
Configure the primary serial port 1/0 to use dialer 1 as its backup interface:
XSR(config)#interface serial 1/0
XSR(config-if<S1/0>)#ip address 100.100.10.1 255.255.255.0
XSR(config-if<S1/0>)#encapsulation ppp
XSR(config-if<S1/0>)#backup interface dialer0
XSR(config-if<S1/0>)#no shutdown
Configure the primary serial port 1/1 to use dialer 2 as its backup interface:
XSR(config)#interface serial 1/1
XSR(config-if<S1/1>)#backup interface dialer 1
XSR(config-if<S1/1>)#encapsulation ppp
XSR(config-if<S1/1>)#no shutdown
