Tip The most common reason for clock slip problems is that the dial-tdm-clock priority parameter is set improperly. Change the default setting for dial-tdm-clock priority from free-running clock to a setting that matches your system requirements.

Saving Configuration Changes

To prevent the loss of the gateway configuration, save it to NVRAM, by following these steps:

Step 1 Enter the enable command and password to go to privileged EXEC mode. You are in privileged EXEC mode when the prompt changes to Gateway#.

Gateway> enable

Password: password

Gateway#

Step 2 Save the configuration changes to NVRAM so that they are not lost during resets, power cycles, or power outages:

Gateway# copy running-config startup-config

Step 3 Return to privileged EXEC mode:

Gateway(config-if)# Ctrl-Z

Gateway#
