TAP200 Auto Reboot

The information in this page is updated in accordance with firmware version TAP200_R_00.07.10.2.

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 TAP200 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. The maximum limit of instances is 30. 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.
Packet size	integer [0..1000]; default: 56	ICMP packet size in bytes.
IP type	IPv4 | IPv6; default: IPv4	IP address version of the host to ping.
Action condition	When all requests fail | When any request fails; default: When all requests fail	Select when the action will be executed.
Host to ping	host | ip; default: 8.8.8.8	Hostname or IP address to which the Ping/Wget requests will be sent.
URL	url address; default: none	URL to which the wget requests will be sent (e.g., http://www.host.com).

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. The maximum limit of instances is 30. If you wish to customize a rule, click the button that looks like a pencil next to it.
