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 docommand followed by the desired EXEC command. This feature provides the convenience of entering EXEC-level commands without needing to exit the current configuration mode.

Finding Feature Information

Your software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the feature information table at the end of this module.

Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to www.cisco.com/​go/​cfn. An account on Cisco.com is not required.

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.

      Example do show interface Command

      The following example shows how to execute the EXEC-level showinterface command from within global configuration mode:

      Router(config)# do show interfaces serial 3/0
Serial3/0 is up, line protocol is up
  Hardware is M8T-RS232
  MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec, rely 255/255, load 1/255
  Encapsulation HDLC, loopback not set, keepalive set (10 sec)
  Last input never, output 1d17h, output hang never
  Last clearing of "show interface" counters never
.
.

      Example do clear vpdn tunnel Command

      The following example shows how to execute the EXEC-level clearvpdntunnel command from within VPDN configuration mode:

      Restrictions for EXEC Commands in Configuration Mode

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