Before the MDS NX-OS Release 4.1(1a), you can execute an EXEC mode command from a
configuration mode or submode prompt. You can issue this command from any submode within the
configuration mode. When in configuration mode (or in any submode), enter the do command along with
the required EXEC mode command. The entered command is executed at the EXEC level and the prompt
resumes its current mode level.
switch(config)# do terminal session-timeout 0
switch(config)#
In this example, terminal session-timeout is an EXEC mode command—you are issuing an EXEC
mode command using the configuration mode do command.
The do command applies to all EXEC mode commands other than the end and exit commands. You can
also use the help (?) and command completion (Tab) features for EXEC commands when issuing a do
command along with the EXEC command.

Displaying the Present Working Context
Some features have configuration submode hierarchy nested more than one level deep. In these cases,
you can display the commands you used to reach your present working context (PWC). To display the
command used to reach the current PWC, issue the pwc command at any command mode prompt.
switch(config-if)# pwc
