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. |
