Enabling monitoring on a link

Enabling monitoring on a link

You can enable monitoring on a link. All links built within the SD-WAN network are displayed in the overall table of links in the Tunnels section, as well as in the graphic topology in the Topology section. A table of links built using a particular CPE device is also displayed in the configuration of that CPE device, on the Tunnels tab.

To enable monitoring on a link, use the following instructions:

Enabling monitoring on a link using the overall table.
To enable monitoring on a link using the overall table:
1. In the menu, go to the Infrastructure section.
  The SD-WAN infrastructure management page is displayed. By default, the Network resources tab is selected, which displays the table of SD-WAN Controllers.
2. Click Management next to the SD-WAN Controller and in the drop-down list, select Configuration menu.
  This opens the SD-WAN Controller configuration menu. By default, you are taken to the Controller nodes section, which displays a table of Controller nodes.
3. Go to the Tunnels section.
  A table of links is displayed.
4. Click Management next to the link and in the drop-down list, select Set thresholds.
5. This opens a window, in that window, select the Enable tunnel thresholds monitoring check box.
6. To use the default monitoring thresholds, click Set to default.
7. If you want to mark the link as charged and prohibit using it for routing or make it the last priority link, regardless of the connection quality, select the Unsolicited check box. This check box is cleared by default.
8. In the Interval for processing errors and utilization rate (sec.) field, enter the time interval in seconds for measuring the number of errors on the link and its level of utilization. Range of values: 1 to 300. The default setting is 60.
9. Select the Enable error monitoring check box to specify the threshold number of errors on the link, and in the Critical error level (errors/sec.) field, enter the value that you want to configure. Range of values: 1 to 1,000,000. By default, the check box is cleared and the field is set to 1,000.
10. Select the Enable utilization monitoring check box to specify the link utilization threshold as a percentage of the configured speed of the service interface and in the Critical utilization level (%) field, enter the value that you want to configure. By default, the check box is cleared and the field is set to 95.
11. In the Interval for processing latency, jitter, and packet loss (sec.) field, enter the time interval, in seconds, for measuring latency, jitter, and packet loss on the link. Range of values: 1 to 600. The default setting is 15.
12. Select the Enable latency monitoring check box to specify the maximum latency in milliseconds for packet transmission through the link, and in the Critical latency level (ms.) field, enter the value that you want to configure. Range of values: 5 to 1,000. By default, the check box is cleared and the field is set to 100.
13. Select the Critical jitter level (ms.) check box to specify the maximum jitter time in milliseconds for packet transmission through the link, and in the Enable jitter monitoring field, enter the value that you want to configure. Range of values: 5 to 1,000. By default, the check box is cleared and the field is set to 100.
14. Select the Enable packet loss monitoring check box to specify the maximum packet loss percentage on the link and in the Critical packet loss level (%) field, enter the value that you want to configure. Range of values: 1 to 100. By default, the check box is cleared and the field is set to 2.
15. Save the settings:
  - Click Save to save the monitoring settings on the link.
  - Click Save for both tunnels to save the specified monitoring settings on the link, as well as on the corresponding link in the opposite direction.
