Configuring modem dial backup

1. From the main context, use the show interfaces Console or show interfaces
usb-modem command to verify that the modem is connected. You may be required to
enable the modem.
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. Use this option when you know what
●
server the dialed string is going to connect to.
Use the command ip address negotiated.
