Chapter 4 Configuring the Data Interfaces
Configuring Asynchronous/Synchronous Serial Interfaces
To configure the Fast Ethernet interface, perform these steps:
Configuring Asynchronous/Synchronous Serial Interfaces
This section describes how to configure the serial interfaces on your asynchronous/synchronous serial
WIC.
Note The asynchronous/synchronous serial WIC supports synchronous mode only.
Timesaver Before you begin, disconnect all WAN cables from the AGM to keep it from trying to run the
AutoInstall process. The AGM tries to run AutoInstall whenever you bring the module online if there
is a WAN connection on both ends and the AGM does not have a valid configuration file stored in
NVRAM (for instance, when you add a new interface). The AGM can take several minutes to
determine that AutoInstall is not connected to a remote TCP/IP host.
Command Purpose
Step 1
gateway> enable
Password: <password>
gateway#
Enter enable mode.
Enter the password.
You know you have entered enable mode when the prompt
changes to
gateway#.
Step 2
gateway# configure terminal
Enter configuration commands, one per
line. End with Ctrl-Z.
gateway(config)#
Enter global configuration mode.
You know you have entered global configuration mode
when the prompt changes to
gateway(config)#.
Step 3
gateway(config)# ip routing
Enable routing protocols as required for your global
configuration.
Step 4
gateway(config)# interface
fastethernet 0/0
gateway(config-if)#
Enter interface configuration mode.
You know you have entered interface configuration mode
when the prompt changes to
gateway(config-if)#.
Step 5
gateway(config-if)# ip address
172.16.74.3 255.255.255.0
Assign an IP address and subnet mask to the interface.
Step 6
gateway(config-if)# exit
Exit back to global configuration mode.
If your AGM has more than one Fast Ethernet interface
that you need to configure, repeat Steps 4 through 6.
Step 7
gateway(config)# Ctrl-Z
gateway#
When you finish configuring interfaces, return to enable
mode.
You know you have entered enable mode when the prompt
changes to
gateway#.
