Chapter 3 Configuring with the Command-Line Interface
Configuring Analog Modem Interfaces
Checking the Modem Configuration
After configuring the new modem interface, you can perform the following tests to verify that the new
interface is operating correctly:
• To verify your group interface configuration, enter the show interface async command.
• To display a summary for all modem lines, enter the show line command.
• To display a summary for a single modem line, enter the show line number command.
If an interface is down and you configured it as up, or if the displays indicate that the hardware is not
functioning properly, make sure that the new interface is properly connected and configured. To check
other parts of the configuration, refer to “Saving Configuration Changes, page 3-65.”
Step 12
Router(config-if)# exit
Exit back to global configuration mode.
Return to Step 4 if your router has more than one
interface that you need to configure.
Step 13
Router(config)# modem country microcom_hdms
country-name
Set modem parameters (including encoding) to the
correct country. Table 3-8 shows country codes.
The default is usa.
Step 14
Router(config-if)# line 1 16
Enter the modem line or range of modem lines to
configure.
Step 15
Router(config-line)# transport input all
Allow all protocols to be used when connecting to
the line.
Step 16
Router(config-line)# autoselect ppp
Enable remote IP users running a PPP application
to dial in, bypass the EXEC facility, and connect
directly to the network.
Step 17
Router(config-line)# modem inout
Enable incoming and outgoing calls.
Step 18
Router(config-if)# Ctrl-z
When you finish configuring interfaces, return to
enable mode.
