Chapter 3 Starting and Configuring the Router
Configuring Synchronous Serial Interfaces
Synchronous serial interfaces are configured to allow connection to WANs through a CSU/DSU. In the
following example, a synchronous serial interface in slot 1 is configured for a WAN connection using IP.
Follow these steps to configure synchronous serial interfaces:
Step 1 Using your own addresses and mask at the setup prompts, respond to the prompts as follows:
Configuring interface parameters:
Configuring interface serial 1/0:
Is this interface in use? [yes]:
Configure IP on this interface? [yes]:
IP address for this interface: 1.1.1.30
Number of bits in subnet field [0]:
Class A network is 1.1.1.0, 0 subnet bits; mask is /24
Determine if you are going to enable IPX on this interface; if you are, enter the unique IPX network
Step 2
number:
Configure IPX on this interface? [no]: yes
IPX network number [2]:
Step 3 If you are using AppleTalk on the interface, enter yes. Enter yes to configure for extended AppleTalk
networks, and then enter the cable range number. Enter the zone name and any other additional zones
that are associated with your local zone:
Configure AppleTalk on this interface? [no]: yes
Extended AppleTalk network? [no]: yes
AppleTalk starting cable range [0]:
Step 4 Save your settings to NVRAM. (See the
page
do not save the configuration settings that you created in the router using configuration mode and the
setup facility, your configuration will be lost the next time you reload the router.
Note If additional synchronous serial interfaces are available in your system, you are prompted for their
configurations as well.
The following example display lists the ATM configuration parameters:
Configuring interface ATM1/0:
Is this interface in use? [yes]:
Configure IP on this interface? [yes]:
Configure IPX on this interface? [yes]:
Configure AppleTalk on this interface? [no]: yes
The following configuration command script was created:
hostname Router
OL-11364-04

IP address for this interface: 1.1.1.10
Number of bits in subnet field [0]: 0
Class C network is 1.1.1.0, 0 subnet bits; mask is /24
IPX network number [2]:
Extended AppleTalk network? [no]: yes
AppleTalk starting cable range [0]:
