EXEC Commands in Configuration Mode

Last Updated: December 3, 2010

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 configure terminal EXEC command because issuing the configure terminal command changes the mode to configuration mode.

Configuration Examples for EXEC Commands in Configuration Mode

•Example: do show interface Command

•Example: do clear vpdn tunnel Command

Example: do show interface Command

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

 Example: do clear vpdn tunnel Command 
 
    
   
 The following example shows how to execute the EXEC-level clear vpdn tunnel command from within VPDN configuration mode: 
 
    
   
 
    
Router(config-vpdn)# do clear vpdn tunnel
