The web-based interface, on the other hand, provides a more user-friendly experience, especially for those new to networking. However, some advanced configurations may only be possible via the CLI. To configure the router via the CLI, you'll need to use the terminal emulator program you used during the initial setup. Log in to the router using your username and password. After logging in, you'll be in the user EXEC mode. To access the privileged EXEC mode, where you can make configuration changes, type enable and enter your enable password when prompted. You can then enter global configuration mode by typing configure terminal. From here, you can start configuring the router's various settings. Some of the key configuration tasks include setting up IP addresses for the router's interfaces, configuring routing protocols like RIP or OSPF, and setting up security features like firewalls and VPNs. To configure an IP address on an interface, go into interface configuration mode by typing interface GigabitEthernet0/0 (or the appropriate interface name) and then use the command ip address [IP address] [subnet mask]. Don't forget to enable the interface with the no shutdown command. Routing protocols are essential for enabling communication between different networks. You'll need to configure the routing protocol of your choice and define the networks it should learn about. Security is critical, so be sure to set up a firewall and, if needed, a VPN. To configure a basic firewall, you'll need to define access control lists (ACLs) to control network traffic. Once you've made all your configuration changes, be sure to save them using the write memory or copy running-config startup-config command. This ensures that your configurations are saved and will be loaded when the router restarts. The web-based interface, if enabled, can be accessed by entering the router's IP address in your web browser. This interface provides a graphical representation of the router's settings, making configuration more intuitive. However, the CLI offers much more flexibility and control. The ISR 1100x offers a wealth of features that you can configure to customize your network. Don't be afraid to experiment and test different settings to see what works best for your needs.
