no
In the enable and configuration mode contexts, typing the word no before a
command negates that command. For example, if you want to stop event
notices from displaying to the CLI screen, enter no events.
do
If you need to execute an enable mode command from a configuration mode
context, type do before you enter the command. The do command allows you
to stay in your current mode context while executing other mode context
commands. For example, to display the status of a physical interface while
configuring its logical interface, enter:
Syntax: do show interfaces <interface type> <slot>/<port>
ProCurve(config-ppp 1)# do show interface e1 1/1
exit
To leave a specific interface or configuration mode, type exit. The exit
command moves you back one mode level. For example, if you were in the
ATM interface configuration mode context and entered exit, you would return
to the global configuration mode context.
When you enter the exit command in the global configuration mode context,
you return to the enable mode context and the CLI displays this message:
Appropriate commands must be issued to preserve configuration.
This message is a reminder to save the configuration you have completed. All
configuration changes are initially saved in the router's running-configuration
file. If the router were powered down, the running config, and any changes
that you have not saved, would be lost.
Save your current configuration by entering either write memory or copy
run startup from the enable mode context.
Bootstrap Mode Context
The bootstrap mode context allows you access your router when a problem
with the software, or a forgotten password, prevents you from accessing it
through a console session. Bootstrap mode is a temporary measure to allow
you enough access to the router to restore it to proper operation.
