3 C H A P T E R Configuring with the Command-Line Interface This chapter describes how to use the Cisco IOS software command-line interface (CLI) to configure basic Cisco voice gateway (VG) functionality. This chapter presents the following major topics: • Configuring the Hostname and Password, page 3-1 • Configuring Fast Ethernet Interfaces, page 3-3 • Saving Configuration Changes, page 3-5 Follow the procedures in this chapter to configure the Cisco VG manually or, if you wish, to change the configuration after you have run the setup command facility (see the "Using the setup Command Facility" section on page 2-1). This chapter does not describe every configuration possible-only a small portion of the most commonly used configuration procedures. For advanced configuration topics, see the Cisco IOS configuration guide and command reference publications. See the "Obtaining Documentation and Submitting a Service Request" section on page -vi. Note If you skipped Chapter 2, "Using the setup Command Facility," and you have never configured a Cisco VG, return to Chapter 2, "Using the setup Command Facility" and read it now. The chapter contains important information that you need for configuring your Cisco VG. Note Cisco VG202 and Cisco VG204 voice gateways are fixed voice gateways and do not support interface cards. Configuring the Hostname and Password One of the first configuration tasks is to configure the hostname and set an encrypted password. Configuring a hostname allows you to distinguish multiple Cisco VGs and routers from each other. Setting an encrypted password allows you to prevent unauthorized configuration changes. Note A hostname can be specified only when the VG has a DNS server available for hostname resolution. Perform the following steps to configure the hostname and password.
