Figure 14 Smart Monitor

By enabling Smart Monitor (known as Link Integrity in the CLI) and setting a target IP address, the AP will periodically (set by the ping interval) check to see if the target address responds to pings. If it fails to respond to a ping after the configured number of retries, it will disable both radios so that no clients can connect to the AP.

This is used to disable the AP when it cannot not reach a critical network element such as the RADIUS server, VPN Terminator, Mail Server etc.

„Disable / Enable: Disables or enables a link check to a host device on the wired network.

„Target IP address: Specifies the IP address of a host device in the wired network.

„Enable: Enables traffic between the host’s IP address and the AP.

„Ping Interval: Specifies the time between each Ping sent to the link host.

(Range:300~30000 milliseconds; Default: 30 milliseconds)

„Number of Retries allowed: Specifies the number of consecutive failed Ping counts before the link is determined as lost. (Range:1~30; Default:6)
