View EVPN Passive Assurance Monitoring Results

After provisioning an EVPN service instance in the network, Paragon Automation automatically monitors the health of the service and its related parameters. You can view the health check results and the alerts generated to indicate if any user action is required. The monitoring data is categorized into accordions and each accordion displays related information and alerts generated.

You can view the following accordions for EVPN service instances:

Physical Interfaces—View health check results for physical interfaces of PE devices through which the VPN service spans. Health check results include parameters such as:
- Link flaps
- Link state
- Input and output bandwidth utilization
- Input and output error counts
- Interface speed
See Physical Interfaces Health Check Results.
Logical Interfaces—View health check results for operation status of the logical interfaces on the PE devices through which the VPN service spans. See Logical Interfaces Health Check Results.
L2VPN—View health check results for L2VPN services. See View L2VPN Health Check Results.
OAM— View health check results for the OAM accordion. See View OAM Health Check Results.
LLDP—View health check results for the LLDP accordion. See View LLDP Health Check Results.

Note:

KPI-related data may not be displayed in the accordion tables and on the graphs when:

There are device errors
The data displayed is derived from or is dependent on another KPI which is not being streamed by the devices
