If your console session times out or you log out of the Management Web Interface before saving your configuration, any unsaved configuration changes will be lost. You must then log back into the system, and repeat the configuration procedure from the beginning. For that reason, it is strongly recommended that you set the console session Timeout interval to a high value when creating or modifying a configuration package, or performing other complex tasks. The default is 60 minutes; the maximum is 9999 minutes. For security reasons, you should then reset it to a lower threshold after completing those tasks.
To reset the console session Timeout interval, do the following:
Select the Configuration tab, and then select the Appliance Settings branch in the navigation tree.
This displays the Appliance Settings page, with the User Accounts tab preselected by default.
2. Select the Miscellaneous tab (far right corner).
This displays the Miscellaneous tab page.
3. Enter the console Timeout value.
In the Timeout field of the Change Web Console Timeout section, enter a higher value (in minutes) up to the maximum value of 9999. The default is 60, which is usually much too brief for an initial configuration session.
4. Click Change Timeout.
This resets the session Timeout interval, and displays a success message when the operation completes.
After a brief interval (a few seconds), the session is terminated and you are automatically logged out of the Management Web Interface. The Login page page appears.
5. Enter the Administrator user name (admin) and password (password), and click Login.
The next step is to upload and install the SD-WAN software license file on the appliance.
