![]() ![]() ROM monitor (ROMMON) mode canĪlso be accessed by interrupting the boot sequence during startup. If your system (router, switch, or access server) does notįind a valid system image to load when it is booting, the system will enter ROM monitor mode. ROM monitor mode is a separate mode used when the router cannot boot properly. As an example, this chapter describes the subinterface configuration mode, a submode of the interface configuration mode. Configuration submodes are used for the configuration of specificįeatures within the scope of a given configuration mode. This chapter describes interface configuration mode, a commonly used configuration mode.įrom configuration modes, you can enter configuration submodes. Hierarchy requires that you enter these specific configuration modes only through global configuration mode. If you later save the configuration, these commands are stored across router reboots.įrom global configuration mode you can enter a variety of protocol-specific or feature-specific configuration modes. Configuration modes, including global configuration mode, allow you to make changes Mode to enter specific configuration modes. In this mode, you can enter commands that configure general system characteristics. EXEC mode commands are not saved across reboots of the router.įrom privileged EXEC mode, you can enter global configuration mode. Most EXEC mode commands are one-time commands, such as show or more commands, which show the current configuration status, and clear commands, which clear counters or interfaces. In privileged EXEC mode, you can enter any EXEC command, because privileged EXEC mode is a superset of the user EXEC mode Normally, you must enter a password to enter privileged EXEC mode. In order to have access to all commands, you must enter privileged EXEC mode, which is the second level of access for the EXEC mode. This level of access is reserved for tasks that do not change the configuration of the router, such as For security purposes, only a limited subset of EXEC commands are available When you start a session on a router, you generally begin in user EXEC mode, which is one of two access levels of the EXEC mode. The standard order that a user wouldĪccess the modes is as follows: user EXEC mode privileged EXEC mode global configuration mode specific configuration modes Ĭonfiguration submodes and configuration subsubmodes. The use of specific commands allows you to navigate from one command mode to another. Entering a question mark ( ?) at the system prompt (router prompt) allows you to obtain a list of commands available for each command mode. The commands available to you at any given time depend on the mode you are in. To aid in the configuration of Cisco devices, the Cisco IOS XE command-line interface is divided into different command modes.Įach command mode has its own set of commands available for the configuration, maintenance, and monitoring of router and network Cisco IOS XE CLI Command Modes Overview.To locate documentation of other commands that appear in this chapter, use theĬisco IOS Master Command List, All Releases.
