Configure 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:
Using your own addresses and mask at the setup prompts, respond to the prompts as follows:
Step 1
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 number:
Step 2
Configure IPX on this interface? [no]: yes
IPX network number [2]:
If you are using AppleTalk on the interface, enter yes. Enter yes to configure for extended AppleTalk networks, and
Step 3
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 "Save the Running Configuration to NVRAM" section on page 28. If you 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.
If additional synchronous serial interfaces are available in your system, you are prompted for their
Note
configurations as well.
The following sample display lists the ATM configuration parameters:
Configuring interface ATM1/0:
Is this interface in use? [yes]:
Configure IP on this interface? [yes]:
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
Configure IPX on this interface? [yes]:
IPX network number [2]:
Configure AppleTalk on this interface? [no]: yes
Extended AppleTalk network? [no]: yes
AppleTalk starting cable range [0]:
