Chapter 3 Configuring with the Command-Line Interface
Purpose
Enable routing protocols as required for your
global configuration. This example uses IP
routing, AppleTalk routing, and Internetwork
Packet Exchange (IPX) routing.
Enter interface configuration mode. You have
entered interface configuration mode when the
prompt changes to
Router(config-if)#.
Enter the transmit clock mode for the selected
ATM interface. The choices are internal, line, or
loop. The default is line.
For T1 interfaces only, specify the cable length
(short or long) followed by the length in feet. You
can view the acceptable cable lengths by including
the ? option after the long or short commands.
Specify the loopback type for this ATM interface
by entering the loopback command followed by
one of the following: line, local, payload, remote.
You can view command descriptions by including
the ? option after the loopback command
For E1 interfaces only, specify the impedance
value for this ATM interface by entering the
impedance command followed by one of the
following: 120-ohm, 75-ohm. You can view
command descriptions by including the ? option
after the impedance command.
Note Your response must match the physical
cable connected to the ATM port:
Enter 75 ohm for coaxial unbalanced
cable, or 120 ohm for twisted-pair
balanced cable.
A response of no impedance selects the
default of 120 ohm.
Enable the ATM interface by canceling the
shutdown state.
When you finish configuring interfaces, return to
enable mode.
