Configuring Asynchronous/Synchronous Serial Network Modules or WAN Interface Cards
memory (NVRAM) (for instance, when you add a new interface). It can take several minutes for the
router to determine that AutoInstall is not connected to a remote Transmission Control Protocol/Internet
Protocol (TCP/IP) host.
Before you begin configuring the asynchronous/synchronous serial interface, make sure you:
•
Connect a console to the router.
•
Power on the router.

Configuring with the Command-Line Interface
Purpose
Enter enable mode. Enter the password.
You have entered enable mode when the prompt
changes to
.
Router#
Enter global configuration mode. You have
entered global configuration mode when the
prompt changes to
Router(config)#.
Enable routing protocols as required for your
global configuration. This example uses IP
routing, AppleTalk routing, and Internetwork
Packet Exchange (IPX) routing.
Enter the interface configuration mode. You have
entered interface configuration mode when the
prompt changes to
Router(config-if)#.
Assign the IP address and subnet mask to the
interface.
Configure routing protocols on the interface. You
must have previously enabled these protocols as
part of global configuration. In this example,
AppleTalk and IPX are being configured on the
interface.
All serial ports are initially configured as
synchronous. Enter this command if you want to
configure the port as asynchronous.
Configure asynchronous parameters according to
your needs.
Configure the asynchronous line setting.
Specify the time that the interface waits in
controlled carrier mode. See
half-duplex timer commands.
To use a port in DCE mode, connect a DCE cable
and set the internal transmit clock signal (TXC)
speed in bits per second. See
Table 3-5
for a list of clock rate settings for your
specific interface. (For ports used in DTE mode,
the router automatically uses the external timing
signal.)
