Maintenance

Overview

When the Zyxel Device is set to work in cloud mode, the Maintenance screens let you mange shell script files on the Zyxel Device, generate a diagnostic file, or view log messages.

Shell Script

Use shell script files to have the Zyxel Device use commands that you specify. Use a text editor to create the shell script files. They must use a “.zysh” filename extension.

Use the Shell Script screen to store, name, download, and upload shell script files. You can store multiple shell script files on the Zyxel Device at the same time.

Each field is described in the following table.

Maintenance > Shell Script
Label	Description
Rename	Use this button to change the label of a shell script file on the Zyxel Device. You cannot rename a shell script to the name of another shell script in the Zyxel Device. Click a shell script’s row to select it and click Rename to open the Rename File screen. Specify the new name for the shell script file. Use up to 25 characters (including a-zA-Z0-9;‘~!@#$%^&()_+[]{}’,.=-). Click OK to save the duplicate or click Cancel to close the screen without saving a duplicate of the configuration file.
Remove	Click a shell script file’s row to select it and click Delete to delete the shell script file from the Zyxel Device. A pop-up window asks you to confirm that you want to delete the shell script file. Click OK to delete the shell script file or click Cancel to close the screen without deleting the shell script file.
Download	Click a shell script file’s row to select it and click Download to save the configuration to your computer.
Copy	Use this button to save a duplicate of a shell script file on the Zyxel Device. Click a shell script file’s row to select it and click Copy to open the Copy File screen. Specify a name for the duplicate file. Use up to 25 characters (including a-zA-Z0-9;‘~!@#$%^&()_+[]{}’,.=-). Click OK to save the duplicate or click Cancel to close the screen without saving a duplicate of the configuration file.
#	This column displays the number for each shell script file entry.
File Name	This column displays the label that identifies a shell script file.
Size	This column displays the size (in KB) of a shell script file.
Last Modified	This column displays the date and time that the individual shell script files were last changed or saved.
Upload Shell Script	The bottom part of the screen allows you to upload a new or previously saved shell script file from your computer to your Zyxel Device.
File	Type in the location of the file you want to upload in this field or click Browse... to find it.
Browse...	Click Browse... to find the .zysh file you want to upload.
Upload	Click Upload to begin the upload process. This process may take up to several minutes.

Diagnostics

This screen provides an easy way for you to generate a file containing the Zyxel Device’s configuration and diagnostic information. You may need to generate this file and send it to customer support during troubleshooting. All categories of settings and shell script files stored on the Zyxel Device will be included in the diagnostic file.

The Debug Information Center screen then displays showing whether the collection is in progress, was successful, or has failed. When the data collection is done, click Download to save the most recent diagnostic file to a computer.

View Log

The NCC periodically gathers log files from the devices being managed by it. Before the NCC pulls logs from the Zyxel Device or when the Zyxel Device is disconnected from the NCC, you can use this screen to view its current log messages.

Note: When a log reaches the maximum number of log messages, new log messages automatically overwrite existing log messages, starting with the oldest existing log message first.

Events that generate an alert (as well as a log message) display in red. Regular logs display in black. Click a column’s heading cell to sort the table entries by that column’s criteria. Click the heading cell again to reverse the sort order.

The following table describes the labels in this screen.
