Configuring Interface Parameters
Asynchronous/Synchronous Serial Interface Configuration
This section contains sample configurations for an asynchronous/synchronous serial interface. Enter the
values appropriate for your router and network. The messages you see may vary.
Do you want to configure Serial1/0 interface? [yes]:
Enter mode (async/sync) [sync]:
Synchronous Configuration
If you select synchronous, you see screen displays similar to the following:
Do you want to configure Serial1/0 interface? [yes]:
Enter mode (async/sync) [sync]:
Some supported encapsulations are
ppp/hdlc/frame-relay/lapb/x25/atm-dxi/smds
Choose encapsulation type [hdlc]:
Note
The following sections describe the prompts for each encapsulation type. For PPP and HDLC
encapsulation, no further configuration is needed.
No serial cable seen.
Choose mode from (dce/dte) [dte]:
Note
If no cable is plugged in to your router, you need to indicate whether the interface is to be used as
DTE or DCE. If a cable is present, the setup command facility determines the DTE/DCE status. If
the serial cable is DCE, you see the following prompt:
Configure IP on this interface? [no]: yes
Configure IP unnumbered on this interface? [no]:
IP address for this interface: 2.0.0.0
Subnet mask for this interface [255.0.0.0]:
Class A network is 2.0.0.0, 0 subnet bits; mask is /8
Configure LAT on this interface? [no]:
Frame Relay Encapsulation
The following lmi-types are available to be set,
when connected to a frame relay switch
[0] none
[1] ansi
[2] cisco
[3] q933a
Enter lmi-type [2]:
Note
The setup command facility only prompts for the data-link connection identifier (DLCI) number if
you specify none for the Local Management Interface (LMI) type. If you accept the default or specify
another LMI type, the DLCI number is provided by the specified protocol.
Enter the DLCI number for this interface [16]:
Do you want to map a remote machine’s IP address to dlci? [yes]:
IP address for the remote interface: 2.0.0.2
Do you want to map a remote machine’s IPX address to dlci? [yes]:
IPX address for the remote interface: 40.1234.5678
