Feature Overview

You can now issue EXEC-level Cisco IOS commands (such as show, clear, and debug commands) from within any configuration mode (such as global configuration mode) by issuing the do command followed by the desired EXEC command.

Benefits

This feature provides the convenience of entering EXEC-level commands without needing to exit the current configuration mode.

Restrictions

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

Determining Platform Support Through Cisco Feature Navigator

Cisco IOS software is packaged in feature sets that support specific platforms. To get updated information regarding platform support for this feature, access Cisco Feature Navigator. Cisco Feature Navigator dynamically updates the list of supported platforms as new platform support is added for the feature.

Cisco Feature Navigator is a web-based tool that enables you to quickly determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or release. Under the release section, you can compare releases side by side to display both the features unique to each software release and the features in common.

To access Cisco Feature Navigator, you must have an account on Cisco.com. If you have forgotten or lost your account information, send a blank e-mail to cco-locksmith@cisco.com. An automatic check will verify that your e-mail address is registered with Cisco.com. If the check is successful, account details with a new random password will be e-mailed to you. Qualified users can establish an account on Cisco.com by following the directions at http://www.cisco.com/register.

Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL:

Executing an EXEC Command in Configuration Mode Examples

The following example shows how to execute the EXEC-level show interface 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

.
