TSW202 Maintenance

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

Summary

This page is an overview of the Maintenance section of TSW202 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 TSW202 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| Port; 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| Restart port; 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.
Ping by	Port | IP; default: 8.8.8.8	Ping IP's by Port or by IP.
Port to ping	port number and number of devices (unsigned integer); default: Port1:1	Port number and number of devices addresses to be pinged. (Number of devices connected must be less or equal to the actual number of connected devices to the port).

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 TSW202 devices.

Create default configuration

---

The Create default configuration section is used to create or delete a file which stores current device configuration. The default configuration can later be loaded in Backup page or via reset button.

Click the 'Create' button to generate default configuration file from your current device configuration.

Backup configuration

---

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, 'Download' button to generate and download the device configuration backup file.

Restore configuration

---

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

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:

• 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 Backup configuration section to verify backup's integrity.

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

Restore default settings

---

The Restore default settings section is used for restoring device's configuration.

Field	Value	Description
Restore to factory defaults	-(interactive button)	Restores device to manufacturer's default settings.
Restore to user's defaults*	-(interactive button)	Restores device to custom configuration set by the user.

* You will not see this button until you have created a User's default configuration.
