EXEC Commands in Configuration Mode

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.

How to Enter EXEC Commands in Configuration Mode

Using the do Command in Configuration Mode

To execute an EXEC-level command in any configuration mode (including configuration submodes), complete the tasks in this section:

    2.    configure terminal

    3.    do command


DETAILED STEPS
     Command or ActionPurpose

    Router(config)# configuration command
     

    Allows you to execute any EXEC mode command from within any configuration mode.

    command --The EXEC command to be executed.

     

    Using the do Command in Interface Configuration Mode

    To execute an EXEC-level command for a specific interface on a router, complete the task in this section:

    SUMMARY STEPS

      1.    enable

      2.    configure terminal

      3.    interface type slot /port

      4.    do command


    DETAILED STEPS
       Command or ActionPurpose
      Step 1 enable

      The syntax for this command varies according to your platform and Cisco IOS release. For complete information, refer to the “Additional References” section.

      • The slot/port argument identifies the slot and port on the router where you are entering do commands.
       
      Step 4 do command


      Example:

      Configuration Examples for EXEC Commands in Configuration Mode

      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.
