Verifying the Initial Configuration

If these messages do not appear, SDM and a default configuration file were installed on the router at the factory. To use SDM to configure the router, see the “Initial Configuration Using Cisco Router and Security Device Manager” section on page 12.

Note Be sure to save your configuration changes occasionally so that they are not lost during resets, power cycles, or power outages. Use the copy running-configstartup-configcommand at the privileged EXEC mode prompt (Router#) to save the configuration to NVRAM.

Step 1 To proceed with manual configuration using the CLI, enter no when the power-up messages end.

Would you like to enter the initial configuration dialog? [yes/no]: no

Step 2 Press Return to terminate autoinstall and continue with manual configuration.

Would you like to terminate autoinstall? [yes] Return

Several messages appear, ending with a line similar to the following:

Compiled <date> <time> by <person>

Step 3 Press Return to display the Router> prompt.

...

flashfs[4]: Initialization complete. Router>

Step 4 Enter privileged EXEC mode.

Router> enable

Router#

Step 5 For configuration using the CLI, refer to the applicable configuration procedures in the Cisco 1700 Router Software Configuration Guide documentation at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/access/acs_mod/1800/sw/index.htm

Step 6 Verify the initial configuration. See the “Verifying the Initial Configuration” section on page 13 for verification procedures.

To verify that the new interfaces are operating correctly, perform the following tests:

•To verify that the interfaces are operating correctly and that the interfaces and line protocol are in the correct state—up or down—enter the show interfaces command.

•To display a summary status of the interfaces configured for IP, enter the show ip interface brief command.

•To verify that you configured the correct host name and password, enter the show configuration command.

•To identify the port numbers of voice interfaces installed in your router enter the show voice port command:

Router# show voice port slot-number/port-number

As an example of voice port numbering, if you installed VICs in both slot 1 and slot 2 of the router, the ports in each of these slots would be numbered as follows:

Slot 1—1/0 and 1/1

Slot 2—2/0 and 2/1

When you have completed and verified the initial configuration, your Cisco router is ready to configure for specific functions. Configuring the Router Using the Cisco IOS CLI

1760 specifications

The Cisco Systems 1760 series routers are part of Cisco’s popular line of integrated services routers, designed primarily for small to medium-sized businesses and branch offices. The 1760 series was introduced to provide robust connectivity and routing solutions that facilitate secure and reliable networking. Aimed at offering flexibility, these routers integrate multiple functionalities to enhance operational performance.

One of the main features of the Cisco 1760 router is its modularity. It supports various interface and service modules that allow for customization based on specific networking needs. This modular design enables businesses to expand their networking capabilities over time without necessitating a complete hardware overhaul. The router typically comes equipped with two WAN slots and numerous interface options, including Fast Ethernet and serial interfaces.

The 1760 series routers also support advanced security features, providing businesses with a secure environment for their data transmissions. Built-in firewall capabilities, along with support for Virtual Private Network (VPN) protocols, ensure that sensitive information remains protected. Furthermore, the integration of IPsec and MPLS security features assists organizations in maintaining secure and scalable connections across diverse networks.

Another characteristic of the Cisco 1760 is its support for various technologies, including Quality of Service (QoS). QoS functionality allows network administrators to prioritize traffic, ensuring that critical applications receive the bandwidth they require while minimizing latency. This ability is particularly valuable in environments where voice, video, and essential data applications compete for resources.

The router’s ease of management is also noteworthy. With Cisco’s IOS (Internetwork Operating System), the 1760 provides a user-friendly interface allowing for straightforward configuration and monitoring. The simplicity in managing the network devices helps reduce the burden on IT personnel and enhances overall operational efficiency.

Further enhancing the router’s capabilities is its support for voice over IP (VoIP) applications, making it an ideal choice for organizations looking to implement modern telephony solutions. The ability to support multiple voice channels while maintaining adequate data throughput positions the 1760 as an attractive option for businesses transitioning to unified communications.

In summary, the Cisco Systems 1760 series routers exhibit a harmonious blend of modularity, robust security, traffic management, and VoIP support. They effectively meet the demands of modern networking environments, making them a reliable choice for organizations aiming to streamline operations while ensuring secure connectivity. With their adaptable design, these routers can serve as a powerful backbone for enterprise networking needs.
