TSW212 Maintenance

The information in this page is updated in accordance with firmware version TSW2_R_00.01.03.1.

Summary

This page is an overview of the Maintenance section of TSW212 devices.

Auto Reboot

Summary

---

Various automatic device reboot scenarios can be configured in the Auto Reboot section. Automatic reboots can be used as a prophylactic or precautionary measure that ensures the device will self-correct some unexpected issues, especially related to connection downtime.

This chapter is an overview of the Auto Reboot section of TSW212 devices.

Ping/Wget Reboot

---

The Ping/Wget Reboot functions periodically send ICMP or Wget requests to a specified IP address or host and waits for a response. If no response is received, the device will attempt the same action a defined number of times at a defined frequency. If there is still no response, the device will execute the specified action (reboot, by default).

The Ping/Wget Reboot section contains one pre-configured rule by default:

To enable the default rule, use the off/on slider next to it. You can add more rules with the 'Add' button or delete them using the 'Delete' button. If you wish to customize a rule, click the button that looks like a pencil next to it.

Field	Value	Description
Enable	off | on; default: off	Turns the rule on or off.
Type	Ping | Wget; default: Ping	Method used for health checking. Ping - sends ICMP requests to the specified host. Wget - retrieves the contents of the specified web server.
Action if no echo is received	Device reboot | None; default: Device reboot	Action that will be executed if there is no response after the specified amount of retries. If None is selected, only a message to syslog will be logged.
Interval	5 mins | 15 mins | 30 mins | 1 hour | 2 hours; default: 5 mins	The frequency at which ping/Wget requests are sent to the specified host.
Interval count	integer [1..9999]; default: 2	Indicates how many additional times the device will try sending requests if the initial one fails.
Timeout (sec)	integer [1..9999]; default: 5	Maximum response time. If no echo is received after the amount of time specified in this field has passed, the ping/wget request is considered to have failed.
URL	url; default: none	URL to which the wget requests will be sent. E.g. http://www.host.com
Packet size	integer [0..1000]; default: 56	ICMP packet size in bytes.
Interface	Automatically selected; default: Automatically selected	Specifies through which interface the pings will be sent. If Automatically selected is set, the pings will go through the main WAN interface.
IP type	IPv4 | IPv6; default: IPv4	IP address version of the host to ping.
Host to ping	host | ip; default: 8.8.8.8	Hostname or IP address to which the Ping/Wget requests will be sent.

Reboot Scheduler

---

The Reboot Scheduler is a function that reboots the device at a specified time interval regardless of other circumstances. It can be used as a prophylactic measure, for example, to reboot the device once at the end of every day.

You can add more rules with the 'Add' button or delete them using the 'Delete' button. If you wish to customize a rule, click the button that looks like a pencil next to it.

The figure below is an example of the Periodic Reboot configuration page and the table below provides information on the fields contained in that page:

Field	Value	Description
Enable	off | on; default: off	Turns the rule on or off.
Interval type	Week days | Month days; default: Week days	Scheduler instance interval type.
Week days	Monday | Tuesday | Wednesday | Thursday | Friday | Saturday | Sunday; default: Monday	Week day(s) when actions will be executed. This field becomes visible when Interval type is set to Week days.
Month day	integer [1..31]; default: 1	Day of the month on which the reboot will occur. This field becomes visible when Interval type is set to Month days.
Month	month(s) [january..december]; default: none	The month(s) on which the reboot will occur. Leave empty to apply to all months. This field becomes visible when Interval type is set to Month days.
Day time	time [00:00..23:59]; default: none	Exact time of day the reboot will take place
Force last day	off | on; default: off	Forces intervals to accept last day of month as a valid option if selected day doesn't exist in the ongoing month. This field becomes visible when Interval type is set to Month days.

Backup

Summary

The Backup page is used to generate configuration backup files or upload existing ones to the device. This chapter is an overview of the Backup page in TSW212 devices.

Create backup

The Backup configuration section is used to generate and download a file which stores the current device configuration. The backup file can later be uploaded to the same device or another device of the same type (product codes must match).

This section contains MD5, SHA256 checksum fields generated from latest downloaded backup file, 'Encrypt' option and the 'Download' button to generate and download the device configuration backup file.

Important notes:

1. Password field is required if Encrypt is turned on and that's when the field appears. Password that will be used to encrypt Backup file. It will have to be provided when extracting formatted zip archive to gain access to a tar file.

2. If the device does not have an Internet connection when a Backup file is being loaded, it will not reinstall software packages installed from Services → Package Manager. You can add the package installation files to the Backup file manually, a TSW212 device will automatically install them when you load the Backup file even without a data connection.

To embed a Backup file with package installation files, follow these steps:

• Download the necessary software package installation files from here
• Download a Backup file.
• Open the Backup file and create a new folder called backup_packages in the /etc directory.
• Add the necessary package files to /etc/backup_packages
• Make sure files in /etc/backup_packages are fully extracted with the *.ipk extensions

Upload backup

The Restore configuration section is used to upload a configuration file that was taken from this device or another device of the same type.

Turn on 'Encrypted' if backup file was previously encrypted and click the 'Browse' button to select a backup file from your computer and click the 'Upload archive' button to apply the selected configuration on to this device.

Important notes:

• Password will be used when extracting formatted 7z or zip archive to gain access to a tar file.
• Backup files can be uploaded only if they are taken from an identical device (identical Product code (can be checked in the Status → System page)) with identical or older firmware.
• It is important to remember that the backup file not only changes the device configuration, but also the password. If you are unsure of the backup file's password, you may want to reconsider uploading it because you may lose access to device.

Backup Security Check

---

After uploading a backup file your device will calculate checksums for uploaded file and display them. If this backup file was the latest downloaded in your device then you can compare these checksums with the ones in your Create backup section to verify backup's integrity.

If everything is in order click Proceed to restore configuration to backup.

Troubleshoot

Logging Settings

---

The Logging Settings section is used to configure how and where the device stores system log data. The system log is a file that contains information on various system related events and is useful to engineers for troubleshooting the device.

Compress	off | on; default: off	Compress old rotated logs using GZ format.
Delete	- (interactive button)	Deletes log file from router.
Show hostname	off | on; default: off	Show hostname instead of IP address in syslog.
