Configuring The Physical Interface For The Dialer Interface; Configuring Interface As The Backup Dialer Interface - Enterasys Security Router X-PeditionTM User Manual

Configuring the Physical Interface for the Dialer Interface

Perform the following steps to set up the physical port for the dialer interface:
1. Enter interface serial card / port to specify the interface.
2. Enter encapsulation ppp to set PPP encapsulation.
3. Enter dialer pool-member pool-number priority priority to assign the interface as a member of
the pool that the dialer interface will use.
Priority is an optional value you can configure to prioritize this pool-member within the pool.

Configuring Interface as the Backup Dialer Interface

Perform the following steps to configure the port for the dialer backup 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 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
be enabled and disabled.
The CLI commands shown below are those used to configure the example shown in
on page 10-14.
Create interface dialer 1 to use dialer pool 6:
XSR(config)#interface dialer1
XSR(config-if<D1>)#encapsulation ppp
XSR(config-if<D1>)#dialer pool 6
XSR(config-if<D1>)#no shutdown
Configure backup serial port for dialing purposes:
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
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
range
