Traffic Health Thresholds
Using Traffic Health Thresholds, you can configure the packet error and packet drop threshold percentage values for computing the health status of port types such as hybrid, network, stack, tool, inline tool, and inline network ports. You can also configure the threshold values for GigaSMART engine port packet correlation, packet drops, and packet errors for computing the health status of GigaSMART engine port.
GigaVUE-FM checks the health status of the ports every 5 min. If the port packet correlation, errors, or drops increment every 5 min and exceeds the configured threshold for a specified time interval, then the port becomes unhealthy. When the port becomes unhealthy, the related maps also become unhealthy.
Note: When a new node or a cluster is added, GigaVUE-FM does not compute the traffic health immediately after the first configuration synchronizing cycle is completed. It takes the next synchronizing cycle to compute the traffic health based on the traffic health thresholds described in this section. While the traffic health is still being computed, the health status of a map is shown as gray (unknown state) in the Physical Dashboards > Unhealthy Maps widgets.

For more information about port health status, refer to the Port Health Status section in the GigaVUE-FM User’s Guide.
You must have fm_super_admin role to configure the traffic health threshold.
To set the traffic health threshold:

|
In the Traffic Health Thresholds page, select any of the following check boxes: |
|
•
|
GigaSMART engine port packet errors: The percentage of packet errors coming into the GigaSMART engine port. |
|
•
|
GigaSMART engine port packet drops: The percentage of packets dropped due to over subscription of a GigaSMART engine port. |
|
•
|
GigaSMART engine port packet correlation: The percentage (%) of packet correlation seen in a GigaSMART engine port. The GigaSMART engine port packet correlation is calculated based on the following factors: |
|
•
|
the cumulative number of packets coming into a GigaSMART group |
|
•
|
the cumulative number of packets going out of a GigaSMART interface |
|
•
|
the cumulative number of packets dropped at a GigaSMART operation for a map |
|
•
|
Port Packet Drops: The percentage (%) of packets dropped due to over subscription of the port. |
|
•
|
Port Packet Errors: The percentage (%) of packet errors coming into the port. |
|
•
|
Port Utilization: The threshold for port utilization. You can configure both the upper and lower threshold limits based on which an alarm is triggered. |

|
Select the required threshold type and click Edit. |
To disable the thresholds, clear the Enabled check box.
|
5.
|
In the Threshold Value box, enter the percentage threshold value. |
|
6.
|
In the Interval box, specify the time interval that the threshold value must exceed for the port to be considered unhealthy. By default, the time interval is set to 15 min. |
