2. Enter interface dialer, followed by the identifier, to create the Dialer
interface.
For example:
Gxxx-001(super)# interface dialer 1
Gxxx-001(if:dialer 1)#
The Dialer interface is created and can now be defined as a backup interface for
an existing WAN interface.
3. Enter up to five dialer strings, using the dialer string command.
For example:
Gxxx-001(if:dialer 1)# dialer string 1 5555555
Done!
Gxxx-001(if:dialer 1)# dialer string 2 1234567
Done!
When the Dialer interface is activated, the Dialer first attempts to dial the number
associated with dialer string 1. If that attempt fails, the Dialer attempts to connect
to the number associated with the next dialer string, and so on.
4. Set the IP address of the Dialer interface with the ip address command.
There are three options:
• Manually set the IP address and subnet mask. Use this option when you know
to which server the dialed string is going to connect. For example:
Gxxx-001(if:dialer 1)# ip address 4.5.6.7 255.255.255.0
Done!
• Enter ip address negotiated.
• Enter ip unnumbered interface, where interface is the name of
another interface in the gateway (for example, the WAN interface) from which
an IP address for the Dialer interface is borrowed. Use this command when
you do not know who will eventually be your peer and you want to run dynamic
routing protocols (for example, OSPF or RIP) over the dialup link.
5. Enter dialer persistent initial delay, with the value 30 seconds, to
prevent dialup after boot, before the WAN link is fully functional.
For example:
Gxxx-001(if:dialer 1)# dialer persistant initial delay 30
Done!
6. If needed, set any of the following parameters:
• Use the dialer persistent max-attempts command to set the
maximum number of dial attempts. For example:
Gxxx-001(if:dialer 1)# dialer persistent max-attempts 10
Done!
The Dialer interface dials each number associated with a dialer string, in order,
until either a connection is made, or the number configured in the dialer
persistent max-attempts command is reached.
