WAN Link Health Detection
It shows WAN link health detection results regarding the reliability of a specific WAN connection. The data are derived based on ping results from destination IP list configurations in System > WAN Link Health Detection (See “WAN Link Health Detection”). It enables to observe the number of sent requests, number of received responses, and the success ratio for a given destination. These statistics assist administrators in further analyzing network status and user behavior.
|WAN Link||:||The WAN link to be monitored.|
|Automatic Refresh||:||Time interval for refreshing tables.|
|Destination IP||:||The destination IP address to which ping requests will be sent.|
|Number of Requests||:||The number of requests sent to the Destination IP so far. A request indicates a ping packet if Detection Protocol is ICMP, or a TCP connection request if Detection Protocol is TCP.|
|Number of Replies||:||The number of responses received so far from the Destination IP. A reply indicates a ICMP echo reply or a time_exceed if Detection Protocol is ICMP, or a system acknowledge indicating TCP connection is established if Detection Protocol is TCP.
Both indicate the success of a single WAN link detection.
|Success Ratio (%)||:||The percentage of responses divided by requests. The higher the percentage, the greater the reliability.|
