Basic Operation Guide 2014/02

The new mode (auto-10) on port A5 is now saved in the startup-config file, and the startup-config
and running-config files are identical. If you subsequently reboot the switch, the auto-10 mode
configuration on port A5 will remain because it is included in the startup-config file.
NOTE: Beginning with K.15.01.0031, configuration changes to ports may require up to 10
seconds to take effect, especially on switches with high CPU utilization. After a configuration
command, perform an appropriate show or show runningconfig command to confirm the
configuration change. If configuration scripts are used, the script should be modified either to check
for successful completion of the previous command before executing the next command, or to sleep
for 10 seconds after the configuration command is executed.
How to cancel changes you have made to the running-config file. If you use the CLI to change
parameter settings in the running-config file, and then decide that you don’t want those changes
to remain, you can use either of the following methods to remove them:
• Manually enter the earlier values you had for the changed settings. (This is recommended if
you want to restore a small number of parameter settings to their previous boot-up values.)
• Update the running-config file to match the startup-config file by rebooting the switch. (This is
recommended if you want to restore a larger number of parameter settings to their previous
boot-up values.)
If you use the CLI to change a parameter setting, and then execute the boot command without first
executing the write memory command to save the change, the switch prompts you to specify
whether to save the changes in the current running-config file. For example:
Figure 13 Boot prompt for an unsaved configuration
The above prompt means that one or more parameter settings in the runningconfig file differ from
their counterparts in the startup-config file and you need to choose which config file to retain and
which to discard.
• If you want to update the startup-config file to match the running-config file, press [Y] for “yes”.
(This means that the changes you entered in the running-config file will be saved in the
startup-config file.)
• If you want to discard the changes you made to the running-config file so that it will match
the startup-config file, then select [N] for “no”. (This means that the switch will discard the
changes you entered in the running-config file and will update the running-config file to match
the startup-config file.)
