What is Ping Watchdog?

Power over Ethernet (PoE) continues to become more common throughout networking and security solutions. Due to the long periods of operation in these fields devices can often encounter problems where devices such as IP Cameras become stuck and unresponsive and require a reboot to get them back online. Gaining access to the correct physical connection to disconnect and reconnect can not only be time consuming but sometimes isn't possible for various reasons. This is where the Ping Watchdog feature comes in.

Ping Watchdog enables switches/APs to intelligently detect unresponsive devices by intermittently communicating with them, if this connection becomes unresponsive they will reboot the relevant PoE port without any intervention from the user.

With Wi-Tek's managed PoE switches you can enable a schedule for each port alongside individual port mode configurations (more on this below). On their unmanaged PoE switches the Watchdog function is Plug and Play with no configuration steps.

Configuring Watchdog on Wi-Tek Managed PoE switch

Step 1: Connect your Wi-Tek PoE Switch to your PC/Laptop via Ethernet.

Step 2: Ensure your computer is in the same IP range.

  1. Open 'Network & Internet Settings'
  2. Click 'Change adapter options'
  3. Right click on your Ethernet adapter and select 'Properties'
  4. Set the following parameters and click 'OK'Select 'Internet Protocol Version 4' and click 'Properties'

IPv4 Configuration
Step 3: Open your internet browser (Google Chrome, Internet Explorer, Firefox etc.). Type in to access the Wi-Tek management page. The default username / password is admin / admin.

Step 4: Click PoE Power Control on the left hand side. Then click PoE Query Configuration.

Step 5: Configure the devices you need to monitor.

Wi-Tek PoE PD Query Configuration

  • PoE Port – Select the port the device is connected to. If the PoE powered device is stuck and stops working the PoE switch will reboot it automatically.
  • PD IP Address – Enter the IP address of the connected device.
  • PD Query Interval – The time between each query sent from the switch to the device.
  • PD Timeout Number – The switch will send packets to the connected device. If the switch doesn't receive a response after the set number, the related port will be restarted.
  • PD Boot Time – The required boot time of the connected device. Setting this incorrectly will mean the port will reboot again before the device is back online.

Once you've filled in the desired parameters, click 'Apply' and your good to go!

Wi-Tek AP Watchdog

Wi-Tek's Access Points (APs) also offer watchdog functionality, great for ensuring the AP stays online by periodically pinging an IP / domain, if unreachable the AP can be set to reboot automatically to regain network connectivity.

How to setup:

After logging into the Wi-Tek AP (default IP: / password: admin), from the left hand side navigation, go to Advanced and then PING-WatchDog.

From here we can setup the address (IP or Domain) to ping, how frequent those ping tests should be, how many failures and the number of timeouts before the set action is performed.

Wi-Tek AP Options

  • Address: Either an IP or a Domain (i.e - Note: If using an IP, it can be set to either an internal or external IP.
  • Checking Interval: How often (in seconds) you want to check the Address.
  • Number of Failure: How many failures allowed before performing the Action.
  • Ping Timeout: How many timeouts allowed before performing the Action
  • Action:
    • Reboot: Restarts the Access Point
    • Close Wireless: Turns off the Access Point's WiFi
    • Restart Network: Restarts the Network
    • Enable Rescue SSID: Enables a new WiFi to enable engineer login

Additional PoE Switch Configuration Settings

Scheduled PoE Restarts

By going into 'PoE Policy Configuration' you can configure each port to reboot on a weekly scheduled time(s) & day(s). Remember to change the policy status to 'Enable' before clicking 'Apply'.

Individual PoE Port Configuration

By going into 'PoE Port Configuration' you can configure each ports PoE mode, Active & Passive PSE type. Useful if the connected device only supports certain modes and the automatic configuration hasn't worked.

Wi-Tek PoE Port Configuration

Select the port(s) by clicking the respective check boxes, change the parameters as required and click 'Apply'. Incorrectly setting manual parameters could damage the connected device.

  • PoE Mode: Automatic / 24V / 48V
  • Active PSE Type: AT / AF
  • Passive PSE Type: AT / AF
