Lists the columns updated in the VPNs table after running simulation analysis and provides options for VPN failure testing.
When running the Simulation analysis tool, you can record worst-case utilization and latency for VPNs. Then, you can select a VPN to fail to its worst-case utilization or worst-case latency using the 
> Fail to WC or Fail to WC latency options, respectively.
All calculations are based on traffic carried by all interfaces used by the VPN for the service class defined for that VPN.
Columns updated in the VPNs table after simulation analysis
These columns are updated in the VPNs table after completion of Simulation analysis.
| Column |
Description |
|---|---|
| WC util |
Worst-case VPN utilization over all failure scenarios. |
| WC failures |
Failures causing the worst-case utilization of the VPN. |
| WC traffic level |
Traffic level causing the utilization of the interface identified in the WC util column. |
| WC QoS violation |
Highest worst-case QoS violation for all interfaces used by this VPN. A QoS violation is equal to the worst-case traffic minus the worst-case capacity permitted (worst-case QoS bound). |
| WC QoS violation (%) |
Highest worst-case QoS violation for all interfaces in this VPN expressed as a percentage of total capacity. |
| WC latency |
Maximum VPN latency over failure scenarios considered. |
| WC latency failures |
Failures causing the worst-case VPN latency. |
