Chapter 2 Configuring the Cable Modem Termination System for the First Time

Configuring Synchronous Serial Interfaces

The synchronous serial interfaces are configured to allow connection to WANs through a CSU/DSU.
Complete the following steps to configure the serial ports:
To configure serial port 0 enter yes:
Step 1
Configuring interface Serial0/0:
Is this interface in use? [no]: yes
Determine which protocols you want on the synchronous serial interface and enter the appropriate
Step 2
responses:
Configure IP unnumbered on this interface? [no]:
Number of bits in subnet field [0]:
If additional synchronous serial interfaces are available in your system, enter their configurations when
Step 3
you are prompted.
Save the configuration to NVRAM:
Step 4
Router# copy running-config startup-config
You must always manually save the configuration settings to NVRAM whenever they are modified.
Note
The following sample display includes a continuous listing of all interface configuration parameters
selected for Ethernet and synchronous serial interfaces. These parameters are shown in the order in
which they appear on your console terminal.
Only one Ethernet and one synchronous serial interface are configured for this example.
Tip
