What mode do you enter to issue configuration commands on a Cisco switch?

To configure a Cisco switch, the correct mode to enter is Global Configuration mode. This mode allows you to issue configuration commands that affect the switch's operation and settings. Once you are in Privileged EXEC mode, which gives you access to advanced commands, you can enter Global Configuration mode by typing the "configure terminal" command.

In Global Configuration mode, you can make changes to the switch’s configuration, such as setting hostnames, configuring interfaces, enabling routing protocols, and applying access control lists, among other tasks. This mode is essential for building and modifying the overall behavior of the device.

In contrast, User EXEC mode is primarily used for basic monitoring and does not allow for configuration changes. Privileged EXEC mode does enable some configuration commands, but it is limited to entering Global Configuration mode before actual modifications can be made. Interface Configuration mode is a sub-mode within Global Configuration mode that is specific to configuring settings for individual interfaces; it does not provide a complete set of configuration commands applicable to the entire switch.
