What task does the command "Router(config-line)#" typically allow you to perform?

The command prompt "Router(config-line)#" indicates that the router is currently in line configuration mode. This mode specifically allows you to configure settings related to the terminal lines on the device, such as virtual terminal (vty) lines used for remote access.

When in line configuration mode, one of the primary tasks that can be performed is setting passwords for the vty lines, which control access for remote users connecting to the router through protocols like Telnet or SSH. Configuring these passwords is vital for securing access to the router, ensuring that unauthorized users cannot gain entry.

In contrast, configuring interface settings occurs in a different configuration mode (interface configuration mode), entering privileged EXEC mode is done from user EXEC mode, and setting a banner message is performed at the global configuration level, not specifically under line configuration mode. Thus, recognizing the context of the command prompt is essential in understanding the associated tasks.
