Command Description
do
The
do
command provides a way to execute commands in
other command sets without taking the time to exit the
current command set and enter the desired one. The
following example shows the
do
command used to view the
frame relay interface configuration while currently in the T1
interface command set:
For example:
(config)#
interface t1 1/1
(config-t1 1/1)#
do show interfaces fr 7
no
To undo an issued command or to disable a feature, enter
no
before the command.
For example:
no shutdown t1 1/1
copy running-config startup-config
When you are ready to save the changes made to the
configuration, enter this command. This copies your
changes to the unit’s nonvolatile random access memory
(NVRAM). Once the save is complete, the changes are
retained even if the unit is shut down or suffers a power
outage.
show running config
Displays the current configuration.
debug
Use the
debug
command to troubleshoot problems you
may be experiencing on your network. These commands
provide additional information to help you better interpret
possible problems. For information on specific debug
commands, refer to the section
Enable Mode Command
Set
on page 24.
undebug all
To turn off any active debug commands, enter this
command.
The overhead associated with the debug command takes up a large portion of your router’s
resources and at times can halt other router processes. It is best to only use the debug
command during times when the network resources are in low demand (non-peak hours,
weekends, etc.).
