Configuring WAN interfaces
2. Use the interface dialer command, followed by the identifier, to create the Dialer
interface.
G350-001(super)# interface dialer 1
G350-001(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.
G350-001(if:dialer 1)# dialer string 1 5555555
Done!
G350-001(if:dialer 1)# dialer string 2 1234567
Done!
On activation, 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 using the ip address command.
There are three options:
Manually set the ip address and subnet mask, as shown in the following example. Use
●
this option when you know what server the dialed string is going to connect to.
Use the command ip address negotiated. This command means that the IP
●
address will be provided by the peer (as in case when dailing to an ISP) once the dialup
connection succeeds.
Use the command ip unnumbered <interface>, where <interface> is the name
●
of another interface in the media gateway (for example, the WAN interface) from which
an IP address for the dialer interface is borrowed. Use this command when you don't
know who will eventually be your peer and you want to run dynamic routing protocols (for
example, OSPF or RIP) over the dialup link.
G350-001(if:dialer 1)# ip address 4.5.6.7 255.255.255.0
Done!
5. Use the dialer persistent initial delay command, with the value 30 seconds, to
prevent dialup after boot, before the WAN link is fully functional.
G350-001(if:dialer 1)# dialer persistant initial delay 30
Done!
