Chapter 3 Configuring with the Command-Line Interface
Configuring a WIC-1DSU-T1/E1 Serial WAN Interface Card
DETAILED STEPS
Command or Action
Purpose
Step 1
enable
Example:
Router# enable
Enters privileged EXEC mode.
Step 2
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3
ip routing
Example:
Router(config)# ip routing
Enables routing protocols as required for your global
configuration. This example uses IP routing.
Step 4
interface
type number
Example:
Router(config-controller)#
interface serial 0/0
Enters interface configuration mode. You have entered
interface configuration mode when the prompt changes
to
Router(config-if)#.
Step 5
ip address
ip address subnet mask
Example:
Router(config-if)# ip address 172.16.74.1
255.255.255.0
Assigns an IP address and subnet mask to the interface.
Step 6
half-duplex timer dcd-drop-delay
value
Example:
Router(config-if)# half-duplex timer
dcd-drop-delay 100
Specifies the time that the interface waits in controlled
carrier mode. See
Table 3-1
for a list of half-duplex timer
commands.
Step 7
clockrate
value
Example:
Router(config-if)# clockrate 7200
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 3-2
,
Table 3-3
, and
Table 3-4
for lists
of clock rate settings for specific interfaces. (For ports
used in DTE mode, the Cisco IAD automatically uses the
external timing signal.)
Step 8
dce-terminal-timing-enable
Example:
Router(config-if)# dce-terminal-timing-enable
When a port is operating in DCE mode, the default
operation is for the DCE to send serial clock transmit
(SCT) and serial clock receive (SCR) clock signals to the
DTE, and for the DTE to return a serial clock transmit
external (SCTE) signal to the DCE.
If the DTE does not return SCTE, enter this command to
configure the DCE port to use its own clock signal.
