SonicOS 7.1 SD-WAN
About SLA Probes
Network path performance metrics are determined using SD-WAN SLA probes, which are similar to Network Monitor Probes. SonicOS supports ICMP and TCP probe types. An SD-WAN SLA probe can be used by multiple Path Selection Profiles, for further information, see About Path Selection Profiles.
The Network| SD-WAN > SLA Probes page shows the dynamic performance data (latency/jitter/packet loss) and probe status for each path (interface) in the SD-WAN group, in both tabular and graphic displays. The display can show data for the last minute (default), last day, last week, or last month.
| # | Number of the probe. The Collapse/Expand icon toggles the display of the graphs. |
| NAME | Name of the SD-WAN SLA probe. |
| SD-WAN GROUP | Name of the SD-WAN group associated with the SD-WAN SLA probe. |
| PROBE TARGET NAME |
Target address object of the SD-WAN SLA probe. This field is empty for VPN based interfaces. |
| PROBE TYPE |
Type of SLA probe:
When "TCP-Explicit Route" is selected, both Port field and "RST Response Counts As Miss" become available. |
| PORT |
Port for the SD-WAN SLA probe. The minimum/maximum values are 1 to 65535. Ports are displayed only for TCP - Explicit Route probe types. A hyphen (–) displays for Ping - Explicit Route probe types. |
| INTERVAL (S) | Time between SD-WAN SLA probes, in seconds. |
| LATENCY (MS) | Round trip delay for the probes sent through a particular path/interface to reach the probe target and acknowledge back, in milliseconds. This is also displayed as a graph below the probe’s entry in the SLA Probe table. |
| JITTER (MS) | Variation in the latency measurements for the probes through a particular path/interface, in milliseconds. This is also displayed as a graph below the probe’s entry in the SLA Probe table. |
| PACKET LOSS (%) | Percentage of probes that are missed of the probes sent through a particular path/interface. This is also displayed as a graph below the probe’s entry in the SLA Probe table. |
| ADDITIONAL INFO | When you hover over the icon, you can view the data for the following: Response timeout, Success Threshold, Failure Threshold, & RST in Failure. |
| COMMENTS |
Displays the comment entered when the SLA probe was configured. |
