Each of these submodes places you deeper in the prompt hierarchy. When you type exit, the switch backs out one level and returns you to the previous level. When you type end, the switch backs out to the user EXEC level. You can also type Ctrl-Z in configuration mode as an alternative to typing end. Note When in configuration mode, you can alternatively enter: • Ctrl-Z instead of the end command • Ctrl-G instead of the exit command You can execute an EXEC mode command from a configuration mode or submode prompt. You can issue this command from any submode within the configuration mode. When in configuration mode (or in any submode), enter the do command along with the required EXEC mode command. The entered command is executed at the EXEC level and the prompt resumes its current mode level. switch(config)# do terminal session-timeout 0 switch(config)# In this example, terminal session-timeout is an EXEC mode command-you are issuing an EXEC mode command using the configuration mode do command. The do command applies to all EXEC mode commands other than the end and exit commands. You can also use the help (?) and command completion (tab) features for EXEC commands when issuing a do command along with the EXEC command. Table 1-2 lists some useful command keys that can be used in both EXEC and configuration modes: Table 1-2 Useful Command Key Description Command Ctrl-P Ctrl-N Ctrl-X-H Description Up history Down history List history 1-10 Cisco MDS 9000 Family Command Reference OL-16217-01, Cisco MDS SAN-OS Release 3.x
