Chapter 3 Installing the Router

Configuring the Router

 

 

 

 

 

 

The setup command facility prompts you for basic information about your router and network, and it

 

 

 

 

 

 

creates an initial configuration file.The prompts vary, depending on your router model, the installed

 

 

 

 

 

 

interface modules, and the software image. The following example and the user entries (in bold) are

 

 

 

 

 

 

shown as examples only.

 

 

 

 

 

 

For a description of the interface numbering, see the “Interface Numbering” section on page 1-5.

 

 

 

 

 

 

 

 

 

 

Note

If you make a mistake while using the setup command facility, you can exit and run the setup command

 

 

 

 

 

 

facility again. Press Ctrl-C, and enter setup at the privileged EXEC mode prompt (Router#).

 

 

 

 

 

 

 

 

 

 

 

 

 

Step 1

To proceed using the setup command facility, enter yes when the power-up messages have ended.

 

 

 

 

 

 

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

 

 

 

Step 2

When the following messages appear, press Return to enter basic management setup:

 

 

 

 

 

 

At any point you may enter a question mark '?' for help.

 

 

 

 

 

 

Use ctrl-c to abort configuration dialog at any prompt.

 

 

 

 

 

 

Default settings are in square brackets '[]'.

 

 

 

 

 

 

Basic management setup configures only enough connectivity

 

 

 

 

 

 

for management of the system, extended setup will ask you

 

 

 

 

 

 

to configure each interface on the system

 

 

 

 

 

 

Would you like to enter basic management setup? [yes/no]: yes

 

 

 

Step 3

Enter a host name for the router (this example uses 3700):

 

 

 

 

 

 

Configuring global parameters:

 

 

 

 

 

 

Enter host name [Router]: 3700

 

 

 

Step 4

Enter an enable secret password. This password is encrypted (more secure) and cannot be seen when you

 

 

 

 

 

 

view the configuration:

 

 

 

 

 

 

The enable secret is a password used to protect access to

 

 

 

 

 

 

privileged EXEC and configuration modes. This password, after

 

 

 

 

 

 

entered, becomes encrypted in the configuration.

 

 

 

 

 

 

Enter enable secret: xxxxxx

 

 

 

Step 5

Enter an enable password that is different from the enable secret password. This password is not

 

 

 

 

 

 

encrypted (less secure) and can be seen when you view the configuration:

 

 

 

 

 

 

The enable password is used when you do not specify an

 

 

 

 

 

 

enable secret password, with some older software versions, and

 

 

 

 

 

 

some boot images.

 

 

 

 

 

 

Enter enable password: xxxxxx

 

 

 

Step 6

Enter the virtual terminal password, which prevents unauthenticated access to the router through ports

 

 

 

 

 

 

other than the console port:

 

 

 

 

 

 

The virtual terminal password is used to protect

 

 

 

 

 

 

access to the router over a network interface.

 

 

 

 

 

 

Enter virtual terminal password: xxxxxx

 

 

 

Step 7

Respond to the following prompts as appropriate for your network:

 

 

 

 

 

 

Configure SNMP Network Management? [yes]:

 

 

 

 

 

 

Community string [public]:

 

 

 

Step 8

A summary of the available interfaces is displayed.

3700 Series specifications

Cisco Systems 3700 Series routers are a pivotal part of Cisco's portfolio, designed for medium to large enterprises aiming to deliver secure and efficient networking capabilities. Introduced as a versatile solution, these routers provide a comprehensive blend of performance, scalability, and investment protection.

One of the standout features of the Cisco 3700 Series is its modular architecture, allowing organizations to customize their router according to specific needs. This modularity supports various modules for different functions, including voice, data, and video, making the 3700 Series an ideal choice for converged networking environments. Administrators can enhance functionality through an array of WAN and voice interface cards that adapt as the organization's needs evolve.

The 3700 Series is built on Cisco's IOS (Internetwork Operating System), ensuring robust and high-quality performance. It supports advanced routing protocols including EIGRP, OSPF, and BGP, facilitating efficient data transmission across diverse environments. This versatility helps organizations implement sophisticated multi-site connectivity and enables reliable performance in complex network scenarios.

Security is a paramount concern in modern networking, and the Cisco 3700 Series delivers with features such as integrated firewall services, VPN support, and intrusion detection capabilities. These security measures protect sensitive data and ensure secure communication between remote sites—critical in today’s cyber landscape.

Another key characteristic of the 3700 Series is its support for Quality of Service (QoS), which prioritizes time-sensitive traffic such as voice and video. By ensuring that critical applications receive the bandwidth they require, organizations can maintain the quality of service that their users expect.

Moreover, the Cisco 3700 Series is designed with redundancy in mind. Features like dual power supplies and hot-swappable fan trays enhance reliability and uptime, which are crucial for mission-critical applications.
