Cisco routers and Cisco switches have many similarities. They support a similar modal operating system, similar command structures, and many of the same commands. In addition, both devices have similar initial configuration steps.
When configuring a Cisco switch or router, the following basic tasks should be performed first:
- Name the device - Distinguishes it from other routers.
- Secure management access - Secures privileged EXEC, user EXEC, and Telnet access, and encrypts passwords to their highest level.
- Configure a banner - Provides legal notification of unauthorized access.
Note: Always save the changes on a router and verify the basic configuration and router operations.
Figures 1 through 4 provide examples of configuring basic settings on router R1:
- In Figure 1, the device is named.
- In Figure 2, management access is secured.
- In Figure 3, a banner is configured.
- In Figure 4, the configuration is saved.
