Chapter 3 Configuring the Cisco 1604 Router

Step 2—Configuring Local AAA Security

interface Serial0 no ip address shutdown

interface BRI0 no ip address shutdown

Step 2 Log in with your new enable password.

Step 3 Exit out of enable mode by using the disable command.

The prompt changes from robo-austin#to robo-austin>.

Step 4 Enter the enable command followed by your password.

Step 5 Enter the show privilege command to show the current security privilege level, which is level 15:

robo-austin# disable robo-austin> enable Password:

robo-austin#show privilege

Current privilege level is 15 robo-austin#

Tips

If you have trouble:

•Make sure the Caps Lock key is off.

•Make sure you entered the correct password. Passwords are case sensitive.

Step 2—Configuring Local AAA Security

The Cisco IOS security model to use on all Cisco devices is authentication, authorization, and accounting (AAA). AAA provides the primary framework through which you set up access control on the access server.

•Authentication—Who are you?

•Authorization—What can you do?

•Accounting—What did you do?

In this case study, the same authentication method is used on all interfaces. AAA is set up to use the local database configured on the Cisco 1604 router. This local database is created with the username configuration commands.

Note Setting up your AAA security at this point in the configuration process is a matter of “best practices”; it ensures that the configuration is managed for most effectiveness.

1604 specifications

Cisco Systems 1604 is a multifaceted router that exemplifies the evolution of networking technology. Introduced in the 1990s, it was designed primarily for interconnecting local area networks (LANs) and wide area networks (WANs). As one of the early routers in the Cisco family, the 1604 laid the groundwork for numerous advancements in the networking space.

One of the standout features of the Cisco 1604 is its modular design. This architecture allows users to customize the router according to their specific needs by adding various modules and interface cards. This adaptability made it popular among organizations that required flexible networking solutions. The router supports multiple types of interfaces including Ethernet, Token Ring, and serial connections, accommodating a variety of networking environments.

In terms of performance, the Cisco 1604 offers impressive capabilities for its time. It supports both routing and bridging functions, enabling it to seamlessly integrate different types of networks. The router can handle up to 4Mbps of bandwidth, sufficient for small to medium-sized network environments. Its built-in memory capacity allows for efficient processing, providing a reliable platform for data communications.

The Cisco 1604 is built on Cisco's proprietary IOS (Internetwork Operating System), which is a critical component of its operation. IOS provides a robust command-line interface for configuration and management, facilitating advanced networking tasks such as routing protocols, security features, and network diagnostics. The support for multiple routing protocols, including RIP, OSPF, and EIGRP, enhances its functionality and compatibility with diverse network architectures.

Security features in the Cisco 1604 are notable, providing essential tools to safeguard data transmitted across networks. It supports various access control lists (ACLs) that enable administrators to regulate network traffic and restrict unauthorized access.

Moreover, the Cisco 1604 was designed with reliability in mind. It includes features like automatic keep-alives for connection monitoring and error-correction protocols to ensure consistent performance.

In conclusion, the Cisco Systems 1604 router represents a significant milestone in networking technology. Its modular design, high performance, advanced IOS capabilities, and robust security measures make it a noteworthy solution for businesses looking to build effective networking infrastructures. While newer models have surpassed its capabilities, the legacy of the Cisco 1604 continues to influence modern networking practices and designs.
