EXEC Commands in Configuration Mode

Beginning in Cisco IOS Release 12.1(11b)E, EXEC-level Cisco IOS commands (such as show , clear , and debug commands) can be entered within any configuration mode (such as global configuration mode) by issuing the do command followed by the desired EXEC command. This feature provides the convenience of entering EXEC-level commands without needing to exit the current configuration mode.

Prerequisites for EXEC Commands in Configuration Mode

You must have your network up and running with Cisco IOS Release 12.1(11b)E or a later release installed.

Restrictions for EXEC Commands in Configuration Mode

You cannot use the do command to execute the configureterminal EXEC command because issuing the configureterminal command changes the mode to configuration mode.
